All samples were fixed in the field he laboratory, bottom samples were washed through d all organisms picked and sorted to the the aid of magnification. Specimens were alcohol solutions and saved for further , Oliqocheata and Diptera were identified Montana, while all other organisms were Roth of Hillsboro, Oregon. 'I Several sampling techniques were used to collect and sample fish populations. Electrofishing qear using a mobile positive from the bank or a stationary boom positive on a small fiberglass boat was used during early sampling periods. Seining was conducted with a 25-foot, 1/4 inch mesh bag seine and a 10', 1/4 inch mesh seine. A fine mesh dip net was utilized when sample site consisted of a small trickle of water. Gill nets (125' experimental and 100', 2-inch bar mesh gill nets) were either drifted through deep holes or dead-set. Traps made of reinforcing bar and covered with chicken wire were baited and fished for channel catfish. Setlines were fished overnight during early spring of 1978, however, they were unsuccessful in capturing any game fish. All game fish were weighed, measured, fin clipped (walleye and sauger) and marked with numbered Floy tags. Scale samples were taken beneath the pectoral fin from the left side. The number of fish of each species was recorded for most samples but when this was not done, relative abundance of each species was recorded. Lengths and weights were not measured on all fish since many of them, particularly cyprinids, are small. Length frequency analyses were completed for those species where such data was taken. Species diversity indicies were calculated for each season according to Newell (1977). RESULTS Physical and Chemical Parameters The runoff pattern of Beaver Creek is typical of a prairie stream, with a bi-modal discharge (Figure 5). Peak runoff occurs in March , followed by a smaller peak in June. Flows then taper off to minimal for the remainder of the year. Maximum discharge for the thirty-year (1938- 1968) period of record at Wibaux was 107 m^/sec (3780 cfs). Historic records indicated flood stages in 1929 and 1872 reaching about 850 m3/sec (30,000 cfs) . Periods of no flow occur regularly. Mean flow at Wibaux (1938-1968) was 0.63 m3/sec (22.3 cfs). General chemical features of the Beaver Creek drainage are shown in Table 1, which summarizes measurements taken during the field study. Alkalinity was high in comparison to other streams, averaging 240 mg/1 at the three stations, reflecting the chemical nature of the drainage. Specific conductance increased with progression downstream, from an -8- Fiqure ^.. [loan riontlilw flows for Heaver Creek near '/ibaux, for period of record ( 1 031-1 9G3). -q. averaqe of 1288 umhos/cm at Station 84, to an average of 1922 umhos/cm at Station 1. Turbidities were generally low for a prairie stream reflecting local runoff as a result of storms. The pH ranged from 6.9 to 8.5 while dissolved oxygen levels were considered good. Chemical features of the tributaries were similar to those of the main stem. The Yellowstone tributaries showed similar water chemistries except alkal initios which were considerably higher. Five day average maximum and minimum water temperatures for April - September, 1977 and 1978 are summarized in Figures 6, 7, 8, and 9. Temperatures exhibited the same general trends with peaks in May and August. The August peak being the yearly maximum. Temperatures declined steadily through late August and September, Maximum temperatures recorded in 1978 were: Section 1 (mouth) 24.3°C; Section 54, 25.0°C; and Section 84, 26. 2^0. Stream Habitat Analysis Stream habitat conditions were measured at 5 Beaver Creek stations, 2 stations on Little Beaver Creek and 7 lower Yellowstone tributary stations. On Beaver Creek, riffles averaged 10.3 cm in depth as compared to 57.4 cm for pools (Table 2). Widths averaged 3.0 m for riffles and 9.3 m for pools. Habitat conditions were analyzed in terms of optimum conditions for pool frequency, pool quality, substrate materials, bank cover and bank stability as outlined in BLM manual 6671 (Duff and Cooper 1976). These parameters are considered "priority A limiting factors." Pool riffle ratios of 50:50 is considered ideal or optimum. Each pool is rated in terms of width, depth and fish shelter and class 1 , 2 or 3 pools are considered good quality pools. Substrate materials are important in terms of fish spawning and aquatic invertebrate production. The amount of each type of substrate material is determined and a ratio of suitable:unsuitable is calculated. Judgements are made concerning bank cover and bank stability. Points are given on each transect, totaled and divided by the total possible to determine the class for the stream reach. Points are totaled, divided by total possible and the percent of optimum obtained. Optimum is considered ideal habitat or 100 percent All sections measured on ranging between 60 and 85 perc was Beaver 59 with a value of bank stability was considered damage. This reach of stream The results of the Beaver Cree conditions on the stream are a Beaver Creek had significantly Beaver Creek showed habitat conditions ent of optimum. The best habitat rating 34.7 percent of optimum. Bank cover and excellent and showed very little ungulate appeared to be \/ery stable and in good shape, k habitat analysis suggests that physical bove average (50% of optimum). Little lower habitat conditions than Beaver Creek. Tributary stream results are shown in Table 3. The best habitat conditions were found on Glendive Creek at Station 14 at 93.7 percent of -10- Table 1 General chemical parameters measured at three sections on Beaver Creek 1977 and 1978.

The upper reaches of Glendive Creek show qood bank cover, stability and very little ungulate use resulting in a high rating. However, the lower reaches of the creek have been altered and the habitat condition rating of 27.7 percent of optimum reflects the stream stability. Box Elder Creek rated good as did Krug Creek, while Cotton Creek and a tributary to Griffith Creek rated fair. Hydrophytes Aquatic plants are an important source of food for waterfowl, muskrats and herbivorous fish and insects, forming the food chain base for game fish and water birds. Cover for fish and aquatic invertebrates is also provided by hydrophytes. A list of hydrophytes found in the Beaver Creek and Yellowstone tributary streams is presented in Table hydrophytes in the study area tend to be widespread This is indicative of a wide ecological tolerance, other four geographical affinities for the United States constitute approximately 15 percent of this list. Most of the species have in common a tolerance of fluctuating water levels, more specifically, a tolerance to low water. As the margins of the creeks gradually recede, the emergent zone has produced a luxuriant growth of grasses, sedges and rushes, literally, a sedge meadow or fen. Representatives of both lotic and lentic waters were identified in compliance with the diversity of the creek habitats. In lieu of the limited soil types in the study drainages, the overall plant community is surprisingly diverse. 4. The species of in geographic affinities.

The substrate and flow patterns of these creeks are not conducive to stonefly development. Intermittence of the creek coupled with sluggish current, shifting and mucky substrates are limiting this group. Stoneflies are most successful in cobble and gravel substrates of permanent streams (Hynes 1976). CaznU, sp and Catiibaetli sp are the two most widely distributed mayflies in Beaver Creek. These two genera are tolerant of a wide variety of environmental conditions but seem to prefer productive, slow moving waters. Cazrvii sp. and CcdllbaeJM) sp. are the dominant mayflies in Sarpy Creek which is similar to Beaver Creek in many respects (Clancey 1977). -17- Yellowstone Beaver Creek C C F F C C C C F F NF R UC UC Table 4.

This group is generally associated with sluggish waters in which they cling and climb among the plant forms. TihnuAa sp. and EnaZlagma sp. appear to be distributed throughout the creek. C/ictmia^op4 t/c/ie sp. is the most common caddisfly in the creek. This genus seems to be tolerant of severe environmental conditions such as warm temperatures, intennittence, low dissolved oxygen levels and shifting substrates which limit other caddisflies. Hifci^ella azteca is found predominately in the upper reaches of the stream. This amphipod is closely tied to sluggish water and a high density of plant materials (Egqleton 1952). The downstream portions of the creek are more lotic and contain fewer aquatic macrophytes which are preferred by HijatzU.a. aztzca. Diptera is the most conmon group of invertebrates in Beaver Creek (Figure 11). Their numbers increase steadily from the mouth up to a point near Section 84 and then decrease. This may be due to intermittence in the upper most sections which eliminates some forms. The chironomid fauna is typical of a warm, slow moving stream. The subfamilies Tanypodinae and Chironominae are widely distributed while the Orthocladiinae are rare. In South Dakota streams Hudson (1971) found Tanypodinae and Chironominae most commonly in slow waters of warm climates. These two groups are tolerant of low oxygen stress (Oliver 1971). The Orthocladiinae are common under a wide range of conditions but in general prefer cooler waters (Hudson 1971). They generally decrease in numbers as water temperatures increase (Oliver 1971). -19- Table 5. Relative abundance of organisms found in each drainage.

All three prefer slow to standing water, low to medium oxyqen concentrations, and eutrophic waters (Beck 1977). i-unnudfviZuA udckemianuA is a common oliqochaete throughout the system. Hiltenun (1970) and Brinkhurst (1974) both state that this species is found under a very wide variety of conditions from extremely productive to oliqotrophic. Hilsenoff (1977) has used invertebrates to evaluate the water quality of Wisconsin streams. Each species was assigned a biotic index value on the basis of the quality of streams from which they were collected. 0 values were assiqned to species collected only in unaltered streams of very hiqh water quality and values of 5 assiqned to snecies known to occur in severely polluted or disturbed streams. Intermediate values were assiqned to species known to occur in streams with various deqrees of disturbance or pollution. Hilsenoff s values were applied to the most dominant groups {Chtumatopiijch ChinonomM sp., Hualcl^a (it^omacu^attit,) and white sucker {Cato.stcmnA cormeAioni] are widely distributed throughout the Beaver Creek system. Fathead minnows and white suckers are cormionly distributed in other small eastern Montana streams. Elser and Schrieber (1978) found white suckers throughout Rosebud Creek and Clancey (1977) found white suckers and fathead minnows to be the two dominant species in Sarpy Creek. The creek chub, while native to Montana, maintains a limited distribution; being restricted to the Yellowstone and Little Missouri River systems in the extreme east-central portion of the state. It is considered quite rare in Montana (Brown 1971). In Wyoming, the creek chub is common throughout many drainages, inhabiting small streams (Baxter and Simon 1970). The creek chub is also comrtion in Missouri, preferring small streams which cease to flow in dry weather (Pflieger 1975). Beaver Creek appears to meet habitat requirements for the creek chub, which do not thrive in streams that maintain strong flows. A length frequency distribution of 390 creek chubs collected from Beaver Creek in 1978 is shown in Figure 16. Fish ranged in length from 30 to 218 mm . Prior to this study, the largest specimen reported in Montana was 147 mm (Brown 1971). The dominant size group was from 41 to 70 mm, making up 43.6 percent of the sample (170 of 390). Several other species found in Beaver Creek also have limited distributions in Montana. The sand shiner [Motfiopli itiaminuiA) is described as a hardy species (Scott and Crossman 1973) which is able to withstand highly variable flows (Summerfelt and Minckley 1969). Erratic flows are comon in Beaver Creek and the sand shinner is common throughout the drainage. The brook stickleback {Cuiaca incomtam) is native to Montana, but is limited to the eastern part of the state, found primarily in tributaries of the Missouri River. While the stickleback is considered tolerant of high salinities comon in intermittent streams (Nelson 1968), its preferred habitat is small, clear streams rich in aquatic vegetation. Distribution of stickleback in Beaver Creek was limited to the upper reaches (above station 74) which meets its habitat requirements. -47- CT) 0) c TO S- o i. o > a; c O OJ c c :3 S- -/n- i I d)0 I I m . .0 D H n OQ C-.

Lenntli-frcfiienc" rlistriliution of creek chubs taken in Beaver Creek, l"/".. -51- Yellow bullheads {Tcta^nAM natal. a>) were collected sporadically in w Beaver Creek. This species is not native to Montana and previously was reported only from reservoirs (Brown 1971). When found in streams, it is generally associated with gravel substrates and aquatic vegetation. The Iowa darter {Etheo.itoma ex.i?e.) is native to Montana in the lower Missouri River and Little Missouri River drainages. Habitat preferences of the Iowa darter is generally slow-moving clear water streams with abundant rooted vegetation (Scott and Grossman, 1973). In Beaver Creek, this species was collected mostly in the upstream sections (primarily above section 68). Habitat conditions in these reaches meet the Iowa darters requirements. Distribution of the river carpsucker {CaA}M.odu caiplo) and the 1 smallnouth buffalo {JctiobiiA bubalM) was restricted to the lower reaches of the stream. Both species prefer pools or quiet backwaters, suggesting that their occurrence in Beaver Creek was the result of movements out of the Little Missouri River. Four species of game fish inhabit Beaver Creek. Walleye [Stizo6tzctLon vitAtim) , sauger (Stizojfe.ciion canademe] , channel catfish [JctaluAuA punctatiLA) and northern pike {E6ox tacliiA) were collected during 1977 and 1978. Walleye - Walleye is the most popular sportfish in the creek. They were collected as far upstream as section 84. This section seems to be a W transition zone on the creek. Upstream of section 84 appears to be too harsh for walleye and also supports low numbers of invertebrates (Figure 10). Walleye may have been introduced into Beaver Creek when they were stocked into Lame Steer Reservoir which drains into Beaver Creek on sampling section 82. The walleye is generally distributed downstream from this site. Walleye are rare in the Little Missouri River (Durre 1977) and are probably rare in lower Beaver also. During the spring of 1978, 13 ripe male walleye were collected in Beaver Creek. No ripe females were collected. These fish ranged between 3 and 6 years old and were captured between April 18 and May 16 when water temperatures varied from B-U^C (41-620F) (Figure 7). This corresponds to the temperatures at which ripe male walleye were collected in Lake Winnebago (Priegel 1970). Other studies have shown that female walleye are present only during the actual spawning period which often occurs during one night (Ellis and Giles, 1965). This probably explains the absence of ripe females in our sampling on Beaver Creek. Length-frequency distribution for walleye collected in 1978 is shown in Figure 17. Walleyes ranged in length from 93 to 672 mm with the size class of 441 to 470 mm making up 12.9 percent. The average length and weight for walleye was 417 mm and 563 grans, respectively, the largest walleye collected weighed 2500 grams. -52- 12- lO- •- Z 4- \ S*ua«r IX] Wdlay* a no S S 260 Langth Imml Finure 17.

This creek would probably only support a put and take fishery due to limited spawninq substrate. Gravel -rubble substrate seems to be preferred by walleye (Johnson 1961). Gradually warminf] water temperatures during spring also appear to be important to strong years classes of walleye (Busch et al. 1975). Rapid fluctuations in water temperatures and flows were common in Beaver Creek as a result of spring time storms and would probably severely reduce reproductive potential of the creek. In Escanaba Lake, Wisconsin, stocked walleye fingerlings added little to the angler harvest in following years (Kempinger and Churchill, 1972), however, in a small lake in Iowa, stocked walleye added significantly to the year class strength (Carlander et al. 1960) in subsequent years. Fishing pressure at the present time would have to be considered light in Beaver Creek. Few fishermen were seen, and of 43 walleye that were tagged in 1978 no fisherman tag returns were reported. Stocking of catchable size fish would increase public interest, possibly to the point that the fishing harvest would be adequate for future stocking. Sauger. Sauger do not maintain a continuous distribution throughout Beaver Creek. This species was collected only as far upstream as section 21 (Figure 13). Most of the larger sauger were collected in spawning condition between April 21 - May 24. Ripe female sauger were collected between April 28 - May 3, corresponding to the period when the highest concentration of sauger was encountered (Figure 14). Water temperatures during this period ranged between 11-12°C (52-540F). In Lake Winnebago, Priegel (1969) found sauger spawning activity to occur between April 24 and May 9 while water temperatures ranged between 43-520F. He concluded that spawning was essentially complete in less than two weeks. Eschmeyer and Smith (1943) reported that sauger below Norris Dam, Tennessee did not spawn when water temperatures were below 50"F. Spawning may have been initiated earlier in Beaver Creek than April 28 but high spring runoff precluded any sampling before this date. After May 4, sauger numbers dropped off drastically (Figure 18). Although sampling efforts remained essentially constant, subsequent catches were low. This probably indicates that the spawning sauger returned to the Little Missouri River. Durre (1977) indicates that the Little Missouri River is important to the sauger populations of Lake Sakakawea. The spawning migration into Beaver Creek probably contributes to this population. Sauger ranged in length from 233 to 561 mm, with 22.0 percent of the sample falling into size class from 411 to 440 mm (Figure 17). The average length was 421 nm and the average wieght was 614 g. The largest sauger collected weighed 1290 g. A total of 41 sauger were tagged and released in Beaver Creek during the spring of 1973. No tags were returned by fishermen indicating that the sauger harvest is light. -54- a: QJ 10 O) CO c o o O) c. to i- r. u a' TO -C? |t|6nD> j«qujn|^ w Lower Beaver Creek is distant from any population center and access is extremely poor in wet weather, explaininq the low level of exploitation. Age and Growth . The lenqth-weiqht relationship of fish can be represented by the formula: w = al° (log w = loq a + b (log 1)). where w = weight, 1 = length, b = regression coefficient and log a = y intercept. The functional regression value b = 3 describes isometric growth, such as would characterize a fish having an unchanging body form and unchanging specific gravity, b values greater or less than 3 characterize allometric growth: if b= 3, the fish becomes "heavier for its length" as it grows larger. There are sometimes marked differences between different populations of the same species or between the same population in different years presumably associated with their nutritional condition. A total of 68 walleye were captured during 1978 in Beaver Creek and figure 19 illustrates the length-weight relationship of these fish. The growth rate of walleye in Beaver Creek is generally slower than walleye in the Tongue River Reservoir (Riggs 1978), however, Beaver Creek walleye have a faster growth rate than walleye in the Yellowstone River and Columbia River drainage in Montana (Peters 1964). The length-weight relationship (Figure 20) was derived from the measurement of 48 sauger captured during 1978. The growth rate of sauger in Beaver Creek is similar to sauger in the Tongue River Reservoir (Riggs 1978) and generally higher than sauger in the Yellowstone River, Fort Peck Reservoir, Milk River, Missouri River (Peters 1964) and Lake Winnebago (Priegel 1969). Channel catfish. Channel catfish are also present in the lower reaches of Beaver Creek near its confluence with the Little Missouri River. A total of 14 individuals were captured in section 1 during May of 1978 when water temperatures ranged from 12-20OC (54-680F). This species was observed as far upstream as section 25 and fishermen reported an occasional catfish caught at Wibaux. Spawning of channel catfish generally occurs at temperatures between 70 and 850F (21-290c) (Clemens and Snead 1957). Those temperatures were common during late June in 1978, however, runoff from rainstorms precluded any sampling during this period (Figure 21). Young of the year channel catfish were collected in section 1 during August and September and section 25 in September indicating that channel catfish utilize lower Beaver Creek for spawning and rearing. Channel catfish probably move up Beaver Creek from the Little Missouri River. After the spawning season is over and the water levels in Beaver Creek reach summer lows, they probably return to the Little Missouri River. McCammon (1956) found downstream movement of catfish in the lower Colorado River in the fall. Other studies have concluded that channel catfish move long distances upstream and downstream from the point of capture (Harrison 1953, Hubley 1963, Muncy 1958 and Messman 1973). Van Eeckhout (1974) found that flows delineate when and how much catfish move ■56- f^ 3500 3000- W = r = .000004785 L .967 3.077 -T- 300 200 300 400 500 TOTAL LENGTH (MM) 600 700 Figure 19.

He also indicates that constant stream discharqe from mid-June to July will generally result in successful reproduction. Droughts and flash floods will result in poor reproduction, poor survival of young and brood stock reductions. While rapid fluctuations in discharge were common in Beaver Creek during this period (Figure 21), successful reproduction did occur. However, reproduction nay have been reduced through environmental fluctuations. Northern pike. Only four northern pike were collected in Beaver Creek, one at section 1 and the other three taken in the middle reaches of the stream. There were at least two age-classes represented in the sample. The northerns ranged in length from 427 to 693 mm and in weight from 500 to 2268 g. Since "jery few northerns were taken in Beaver Creek, it is possible that they are in the creek as the result of stocking a stock- water reservoir. Northerns do not contribute to the recreational fishery of the stream. Species Diversity. Measures of species diversity are another tool for the quantitative and qualitative description of fishery. Investigations of longitudinal zonation in stream fishes reveal that, in relatively unpolluted systems, diversity increases downstream (Sheldon 1968), meaning the number of species increases with proximity to the river's mouth. a f^ Factors v/hich determine the upstream limits of particular species also apparently contribute to the regulation of species diversity. A study by Tramer and Rogers (1973) found that variations in water quality upset the normal pattern of longitudinal zonation of fishes. Where streams are undergoing stress fron pollution, species diversity may remain at levels similar to those in the headwaters throughout the entire system. The disappearance of some of the headwaters species is balanced by the appearance of others, and gains in the abundance of one species are canceled out by losses in another. Therefore, from baseline data, a change in water quality can be reflected by a chanqe in species diversity. It is a generally accepted concept that a large-scale environmental stress exerted upon a diverse biological comunity results in a reduction in species diversity (Cairns 1969). While species-diversity indices have been used extensively with benthic macroinvertebrates to evaluate degradational environmental conditions, they have only recently been applied to fish populations (Sheldon 1968, Jackson and Harp 1973, and Harima and Mundy 1974). Shannon-Weaver diversity indices were calculated for the 1977 and 1978 samples (Table 7). In 1977, d ranged from 1.519 to 2.70 as compared to 0.996 to 3.022 in 1978. No trend in d from source to mouth was noted in Beaver Creek similar in magnitude to those calculated on other Montana prairie streams. ". gfiacifxA) , silver minnow {Hijbognathti6 ahgijhxtif,) and the plains minnow (//. placld^A] . The percent composition of these two complexes in Beaver Creek for 1977 and 1978 is shown in figures 22 and 23, respectively. Although the percentages of each complex vary somewhat between years, the association between the two is similar. The flathead chub complex dominates the lower portions of the creek while the creek chub complex is dominant in the upper reaches. Section 24 appears to be the transition zone for the complexes with the creek chub complex showing dominance upstream from this section. Together, the complexes generally dominate the fish numbers throughout the creek. In areas not dominated by the complexes, goldeye tend to be abundant in the lower reaches, replaced by white suckers upstream. The flathead chub complex prefers turbid waters which flow over silty, pebbly substrates and the creek chub complex chooses clearer water and can withstand mucky habitats with extensive rooted vegetation (Brov/n 1971 and Baxter and Simon 1970). Sauger show close association with the flathead chub complex but walleye are associated with both complexes. Sauger are found as far upstream as section 21, which is about where the flathead chub complex begins to lose dominance. Considering the piscivorous nature of sauger and walleye, these complexes probably represent important forage bases. Goldeye {Hiodon alofiOldeA] are abundant in Beaver Creek. Although little information is available concerning competition of goldeye, walleye and sauger for food, space, shelter, and spawning sites, the possibility may exist and may limit walleye and sauger numbers. Spawning for goldeye occurs at temperatures between 10-12. 80C (59-550F), corresponding to the spawning period of sauger and walleye. Although goldeye generally spawn in pools and backwaters, competition for space is likely to occur. Goldeye feed extensively on the water surface for insects so competition for food is unlikely. Large numbers of goldeye could prey heavily on walleye fry. Creek chubs are the only other piscivore present in large numbers in Beaver Creek. The goldeye and flathead chub complex are predominantly downstream. In contrast, the creek chub and fathead minnow are generally most corrmon in the upstream sections. The white sucker is cormion throughout the drainane. Game fish compose a small percent of fish species present.

Figure 10 shows the aquatic invertebrates collected in Beaver Creek tributaries and their distribution. Little Beaver Creek. A total of 20 species of fish were collected in Little Beaver Creek (Table 9). Distribution and relative abundance of the major species is shown in Figure 24. Only the brook stickleback was distributed throughout the stream, representing the only species found in the headwaters. Walleye, northern pike, yellow bullhead, goldeye, yellow perch and shorthead redhorse were found only in the middle reach. The creek chub dominated the lower section. Hay Creek. Seven species of fish were taken in Hav Creek, with fathead minnows being the dominant species, found in both sample sites (Table 9). Other species found were similar to species found in Beaver Creek. Lame Steer Creek. Table 9 shows the fish distribution of Lame Steer Creek. Two species, fathead minnows and carp ranged throughout the stream. The remaining five species were found near the mouth and approximate the fish populations of Beaver Creek. Lame Steer Lake as a probable so Reservoir was bu waterfowl . A f 1 1953. In 1954, nets fished in 1 bullhead, and 1 crappies (Alvord of the fish popu The fish populations of Lame Steer Lake were sampled urce of the walleye found in Beaver Creek.

Two gill 956 took 253 crappie, 90 suckers, 1 carp, 2 walleye, 1 bluegill. In 1957, a gill net tool 46 suckers and 23 1959). Recommendations in 1959 were against rehabilitation lation until fishing pressure warranted such action. Gill nets were again fished in 1977 to check on the walleyes. A total of 12 walleyes were taken, ranginq in lenqth from 185 to 505 mm. The inclusion of several size classes indicates that walleyes are reproducing in the lake. Other fish taken were 187 carp, 28 white suckers, 4 carp and 4 black bullheads. Since walleyes have maintained themselves in Lame Steer Reservoir naturally since 1954, it is probable that this is the source of walleye in Beaver Creek. Early correspondence about Lamesteer Reservoir suggested that fish had easy access to the reservoir via the spillway during spring runoff. It is also possible then that fish spill out into the stream via the spillway. -65- 1 Table 8. General water chemistry parameters measured on Beaver Creek tributaries, 1977 and 1978.

Chemical parameters for each stream are shown in Table 10. The invertebrate fauna of these tributaries is similar to that of Beaver Creek. Hmfcfln azteca, CkiwnomuA, EndochiAonomui , and Vapknia are very common throughout the lower Yellowstone basin. A list of the aquatic invertebrates collected in each tributary is presented in Fiqure 10. Smith Creek. (Table 11), A total of 21 species of fish were collected in Smith Creek The downstream sections near the mouth of the creek are dominated by creek chubs, brassy minnows {HubagnathM hantzlmoni] , white suckers and brook sticklebacks. Younq-of-the-year northern pike and channel catfish were collected durinq the fall of 1978, suqqestinq that adults of these species migrated into Smith Creek from the Yellowstone River in the spring and summer of 1978 to spawn. While adults were not taken, the presence of young-of-the- year fish indicate the importance of this tributary. Box Elder Creek. A kite diaqram of the fish distributions and relative abundance of fish in Box Elder Creek is presented in Fiqure 26. A total of 19 species were found in the stream (Table 11). The flathead chub, silvery minnow and river carpsucker dominate the lower sections of the creek. These species are common near the mouth of creeks which run into the Yellowstone River. The lake chub {CoveAliiA plumbeiiA] and plains killifish become abundant about midway in the creek. The creek chub is by far the dominant species throuqhout most of the creek. The white sucker is common except for the headwaters. Lake chubs, fathead minnows, emerald shiner (Wotic'pc6 atke^nyinoideA) and sand shiner appear to be headwater soecies. These four species dominate the upper portions of the creek because of their tolerances to extreme habitat fluctuations. The sturgeon chub [HijboiMli, gttida) was collected durinq 1977. This species is rare in Montana and has only been collected in the lower Yellowstone and it's tributaries. Habitat preference of the sturgeon chub is turbid water over qravel substrate with moderate to stronq current, restricted the species to the turbid prairie streams. The presence of the northern redbelly dace {PhoxinuA e.06] in Box Elder Creek is the first occurrence of this species outside of the Missouri River drainaqe. They were probably introduced into the drainaqe as a bait fish by anqlers. Cotton Creek. Five species of fish were collected in Cotton Creek (Table 11). The plains killifish {fundtLtiLS kamaa) is abundant in this stream. Prior to 1971, knov/n distribution of this species in Montana was limited to the Biq Horn River drainaqe (Brown 1971). It has now been collected down- stream in the Yellowstone River where it has established itself in small feeder streams. Killifish seem to prefer shallow sandy bottomed streams which vary qreatly in their thermal and chemical features (Minckley and Klaassen 1969).

The importance of the aquatic resources in relation to surface coal mininq is therefore recoqnized. A ratinq procedure developed by Holton and McFarland (1978) was utilized to assiqn each stream a species and habitat value and a sport fishery potential value. The fish resource value was then assiqned. The value assiqned for species and habitat was determined by a point system in which most points were awarded for important habitats of fish species of special concern. Native species found in limited numbers and/or limited waters were considered of special concern. Fewer points were awarded to less important habitats of species of special concern and for widespread species occurrinq in larqe numbers. Least points were awarded for non-indiqeneous species considered of minimal value. Points were also qiven for esthetics and for importance to local connunity for scientific study, nature study and/or recreation. The procedure for the ratinq system is included in Appendix III. Sport fishery potential was based on a point system in which points were awarded for (1) productivity as indicated by biomass or numbers and sizes of qame or sport fish, (2) leqal riqhts of the public to fish or will inqness of a landowner to permit fishinq, (3) esthetics and, (4) use by fishermen (fishinq pressure). Six value classes were established and a stream was rated accordinq to its score as follows: Value Class Class Identification 1 2 3 4 5 6 Hiqhest valued fishery resource Hiqh priority fishery resource Substantial fishery resource Limited fishery resource Low value fishery resources Neqliqible fishery resource or not classified The value and subsequent ratinq for each stream covered by this study is summarized in Table 12. Computer printouts for each stream reach are in Appendix III. Beaver Creek received the hiqhest ratinq of the streams under consideration, with a value class of 2. Habitat for the creek chub, a class C species of special concern was considered to be substantial in Beaver Creek. Since Beaver Creek is the only perennially flowinq stream in the area, it was qiven special consideration as beinq important to the cormunity. Points accumulated from the remaininq species brouqht the total to 10.9. A class 2 stream is considered to have a hiqh priority fishery resource and should be protected. Activities planned for the Beaver Creek drainaqe ■73- should be carefully reviewed to insure that this unique aquatic resource is protected. The water storage project planned for Beaver Creek will undoubtedly affect this resource. Instream flows necessary to maintain the integrity of Beaver Creek must be identified and maintained. Box Elder Creek also received a high rating with a value class of 2. The creek was considered to have high priority habitat for the creek chub and kill- ifish, both class C species of special concern. Limited habitat for the sturgeon chub, a class B species of special concern also increased the rating. The points accumulated from the remaining 16 species placed the value rating at 10.0. Sport fishery value was only 5, receiving a class 4 rating, which is not surprising considering the scarcity of game and sport fish. Since this class is considered to have a high priority fishery resource, activities which may affect the aquatic resources should be discouraged. Coal lease applications for Box Elder Creek drainage should not be considered until further research has shown that the quality and richness of this resource is not jeopardized. Water resource development projects being considered for this drainage should be reviewed very carefully to insure that the integrity of the system is maintained. Table 12.

Smith Creek, Little Beaver Creek and Krug Creek, were rated as class 3 streams on the basis of species and habitat values. Habitat values for the creek chub and plains killifish accounted for the classification. Class 3 streams have a substantial fishery resource. Resource development activities in these drainages should be reviewed to protect the aquatic resources. Guidelines should be established and followed, however, to prevent substantial riparian damage. -74- DISCUSSION Flow reqime, physical characterist stream norpholoqy of Beaver Creek, it's tributaries to the lower Yellowstone Ri to other southeastern Montana prairie s is usually characterized by two hiqh-wa larqest, occurs durinq late winter or ea snowmelt runoff, while the second occur with the sprinq rains. Flows for the s represent an extremely low flow, while averaqe. ics, chemical parameters and tributaries and the small ver were found to be similar treams. Runoff in Beaver Creek ter periods. The first, and rly sprinq and represents lowland s in later sprinq and coincides treams in the study area in 1977 1978 is considered above Diptera is the most abundant and widely distributed qroup of aquatic invertebrates in the Beaver Creek drainaqe. The invertebrate fauna found in Beaver Creek and the tributaries are characteristic of intermittent prairie streams. Distribution patterns in these streams are influenced by the sluqqish water and their intermittent nature. Species which complete their life history in one season appeared to dominate the invertebrate fauna. Fishes found in the Beaver Creek drainaqe are similar to those found in other eastern Montana streams (Elser et al . 1978, Elser and Schrieber 1978, Clancey 1977). Some exceptions particularly creek chub, Iowa darter, brook stickleback and plains killifish were noted and their distribution identified. In qeneral most species were distributed in Beaver Creek in one of three ways: i.e. found only near the mouth, present only in the headwaters, or distributed throuqhout (Fiqures 13 and 14). Those species found only near the mouth were likely miqrants from the Little Missouri River. Water temperatures, water quality and substrate in the upper reaches favored those fishes found in this area. Other species existinq throuqhout the creek are obviously tolerant of the entire ranqe of conditions and habitats existinq there. Comparisons of fish numbers between stations were difficult to make because samplinq conditions between stations varied qreatly. However, for a qiven station, the numbers of each species sampled probably indicate their relative densities. In addition, the abundance or scarcity of certain species at a qiven station probably reflects the suitability of habitat for those species involved. There seemed to be little uniformity in species diversity of the ichthyofauna within the study area. Diversity was qreater above the Montana-North Dakota boundary than below. Samples were not taken frequently enouqh nor were they of adequate size to allow a completely quantitative assessment. Observations suqqest that sauqer, walleye and channel catfish utilize Beaver Creek for spawninq. The importance of this stream to maintaininq the fish populations of Lake Sakakawea and the Little Missouri River is unanswered. The lack of anqler returns of taqqed fish indicates an under-utilized resource. This is not unexpected since fishinq pressure is low reflectinq the sparse human population density of the area. ■75- Younq-of-the-year sport fish taken in the Yellowstone River tributaries indicates the importance of these streams for maintaining the integrity of the lower Yellowstone. While it is difficult to evaluate the relative importance of these streams to the reproductive potential of lower Yellowstone fish populations, it demonstrates that these streams do provide spawning and nursery areas. When resource development decisions are made, the importance of these tributaries should be considered. Channel catfish and northern pike were collected in Smith Creek, but may also utilize other streams as well. 5 Classification of streams in the study area indicates that these prairie streams are important from the standpoint of species and their habitat values. A serious problem in the preservation of aquatic habitat is the measurement of the total worth of a stream. A fishery (either recreational or scientific) does not lend itself to conventional means of measurement and is too often sold short in comprehensive planning that involves water resources. Two streams inventoried in this study, Beaver Creek and Box Elder Creek, were placed in resource value class which is considered high priority resource fisheries. Decisions concerning resource development in these drainages should be made only after the potential impacts are carefully considered. Among the primary concerns about leasing Federal coal reserves and the subsequent energy devleopment are the effects of coal extraction on water quality, the influences of water withdrawals for coal combustion and the impacts of water storage projects for marketing the water in other basins. In a strip mine operation, topsoil and overburden are removed and set aside, sections of a coal seam removed and consumed, and eventually the void is refilled with overburden (spoils) and recovered with the stored topsoil. As a result of this operation, the normal flow of the aquifer and of surface water is disturbed. Natural chemical and biological processes are altered, hastened or retarded. These may affect the quality of water passing through the mine site area, and in turn alter the biological structure of the subsequent receiving waters - the nearby streams, rivers, ponds and lakes. Studies on the influences of coal mining on subsurface and surface water quality have suggested major impacts (Thurston, et al. 1976). Ground and ground water disturbances associated with mining activity enhances mineralization processes and thereby increases the rates of dissolution of many ionic substances in natural waters (VanVoast and Hedges, 1975). Therefore, it appears likely that coal mining operations in the Beaver Creek or lower Yellowstone basins would alter the water quality and impact the aquatic system. Discharge waters from the West Decker mine have been shown to contain higher concentrations of certain ions than the receiving waters (Whalen, et al. 1976). Water running over mine overburden and spoils result in relatively large amounts of soluble sulfate and carbonate compounds being leached from the overburden and spoils, resulting in an increase in salinity. Beaver Creek, Little Beaver Creek, Box Elder Creek, Smith Creek and Krug Creek all were classed as substantial or better fishery resources and should be protected from environmental degradation. -76- Mercury enrichment of mine water is another problem associated with coal nininq. Phillips (1978) has found higher concentrations in Decker mine discharge water; however dilutional rates were high enough so that the mine does not appear to have a detectable influence on the mercury content of the Tongue River or Tongue River Reservoir, tleavy metal contamination of streams in the Beaver Creek drainage and lower Yellowstone River tributaries is however, a possible impact of coal development in this area. Intake Water Company, a wholly owned subsidiary of Tenneco, Inc., has proposed construction of an off channel reservoir on Box Elder Creek, and a mainstem reservoir on Beaver Creek. An appropriation for 80,650 acre- feet of Yellowstone River water per year was filed by Intake Water Company. This water will be pumped to the detention reservoir on Box Elder Creek. An impoundment on Box Elder Creek would have a negative effect on the diverse biota of this stream, unless measures are taken to provide adequate instream flow values. Several native Montana species which are of special concern are found in Box Elder Creek: creek chub, sturgeon chub and plains killifish; and their integrity must be maintained. Water will then be pumped into the reservoir on Beaver Creek and marketed in industrial areas. However, Intake Water Company is currently involved in a legal battle to obtain permission to transport Yellowstone basin water into the Little Missouri Basin. Not only questions involving states rights, but also questions concerning the Yellowstone Compact are involved. Several locations for the reservoir have been discussed. Depending on the final site and future irrigation demands in the area, the downstream fishery will be dependent on releases from the reservoir. The fishery in Beaver Creek is also diverse and adequate flows must be maintained below the dam if the integrity of the fishery is to be maintained. Instream flows adequate to provide habitat must be maintained. It is doubtful if a quality recreational fishery could be maintained in the reservoir. Lamesteer Reservoir has not been able to provide a sustained quality fishery and there is no reason to believe that a mainstem reservoir would be any better. Additionally, the Beaver Creek Reservoir would be subjected to large fluctuations in water levels due to industrial use of the water. Baseline information on the current aquatic invertebrate and fish species composition, distribution, and abundance in Beaver Creek, its tributaries and tributaries to the Yellowstone is important and necessary to detect any future changes inihe aquatic cormunities resulting from coal leasing, mining and energy conversion. Additional studies to monitor the aquatic populations should be planned so future effects can be detected and remedial action taken if and where necessary. -77- LITERATURE CITED f Alvord, W. 1959.

As used here Ingreiis means the lepal rlpht to enter. Code 1 - Stream section bordered almost entirely hy public l.inds whioh Insure Ingress by .inRlers (exclude state school sections). 2 - A stream section bordered by .i mix of private' .ind public land where the public land Is distributed in such a way that no significant portion of the stream is unavailable by vehicle and/or walking. Floating may also be a major oeans of access. 3 - A strc.im section boi-dcred by roo.fltly private lind where ingress Is uncontrolled or readily available by permission. This portion may be available by floating or through navigability laws. Also Includes corporate lands - these are currently open but could go to individual ownership In the future or company policy regarding ingress could change. It - A stream section bordered mostly by private l.inii where Ingress is limited but some fishing is allowed. May Includi- minor portions where public land or road crossing may provl.le limited Ingress. The portion through private land may be available by floating or through navigability laws. 5 - A stream section bordered entirely by private land where public fishing is a- vailable for a fee or where a small group has leased exclusive rights. Legality ■ay be in question on some streams but this category identifies the current "fee" or "lease" fishing areas. 6 - A stream section bordered mostly by private land where little or no Ingress by permission is allowed. Floating precluded by stream size or other physical limitation (no road or public land to reach stream). 7 - A stream or stream segment bordered by publ ic land that is unavailable because of posting on private land or locked gates on private roads. FISH ABUNDANCE RATINGS. Abundance of fish refers only to adult fish, or in case game and sport fish to keeper size (7" minimum for trout; exception 6" minimum for trout populations which spawn when shorter than 7"). By nature abundance ratings are subjec- tive. Since trout command the most Interest of Montana fishes, the abundance ratings for ,ill fishes were geared to trout. The abundance graph (Figure 1) is a guide to numbers associated with abundant, common, uncommon and rare. The ratings reflect the peak abundance during the year, e.g., when migratory spawners are present. A ' Abundant B ' Abundant with proportional number of bragging size (see appendix) C - CoiBon D ' Connon with proportional number of bragging size (see appendix) U - Uncommon V • Uncommon with proportional number of bragging size (see appendix) R - Rare E - Presence not verified but expected M <■ Species absent but could be present If habitat problems corrected N - Not present I" = Species absent, but might be present if Introduced (e.g., potential habitat In a barren stream) 7. " AbinidHnf-r iiiikiKi%^ Sneclal codes entered lii abundance column to indicate habitat value of reach for spi'c les uT special concern. ^P i 11 I G = Highest-valued H = High priority S = Substantia] value L = Limited value CODKS FOR FISHES' USE 01' REACH Codes indicating single use or dominant use: L = Resident throughout life cycle A = Spawning elsewhere (Includes hatchery fish) — spends part or most of life In reach H = Spawning and hatching — young promptly move downstream .1 = Spawning and nursery to subadult C = Passing through — species uses reach as a corridor to migrate upstream and return downstream F = Feeding run N = No use (in connection with abundance codes M, N md P) Z = Use undetermined Codes that are combinations of the above codes to indicate more than one population of a species. R = L plus H or J P = C plus L, A, H or J S = H and J combined Any other combination: Code entered for dominant use ESTHETICS RATINGS. Esthetics were rated 1 (low) through 5 (high). Features that detract from esthetics Include: pollution, dewaterlng, channelization, riprap (particularly car bodies and discarded building materials), mine tailings, a busy highway along stream and severe land abuse. As a guide: 1 - A stream with low esthetic qualities. 2 - A stream and area with fair esthetics qualities. 3 - A water with natural beauty but of a more common type that listed under 4 and 5. A clean stream in an attractive setting. 4 - A water comparable to 5 except that it may lack pristine characteristics. Presence of human development such as roads, farms, etc., usually comprise the difference between 4 and 5. 5 - A water of outstanding natural beauty In a pristine setting.
