Effects of the 1975 Mike Horse Mine Tailings Dam Failure

on Water Quality and Aquatic Resources of the

Upper Blaclcfoot River, Montana'

INTRODUCTION

On June 19, 1975, the Mike Horse Tailings Dam, located on Beartrap Creek and controlled by
the Anaconda Company, in the headwaters of the Blackfoot River near Lincohi, failed due to
heavy precipitation and runoff from winter snowpack. Failure of a bypass structure and canal that
normally diverted Beartrap Creek flows around the dam caused runoff to fill the pond, overtop
the dam and wash out the east abutment. Runoff water carried heavy loads of gray-colored,
pyritic tailings out of the pond area and into the Blackfoot River. Temporary repairs made by the
company allowed most of the runoff water to be diverted around the tailings pond, reducing the
amount of tailings material entering the river below. However, seepage water from within the
pond site continued to carry smaller amounts of material into the river for approximately three
weeks. The gray-colored water was evident 15 miles downstream before it became obscured by
high, muddy waters of Landers Fork, a major tributary stream (See photos at end of report).

This report summarizes water quality and biological changes which occurred following dam
failure.

Water quality, streambed sediment samples, bottom fauna and fisheries data were collected
during the problem period. These data were compared with similar data collected during a
baselme study from 1970-1973 in anticipation of a proposed open pit mining venture by the
Anaconda Company in the Mike Horse Mine area (Spence 1975).

A description of the upper Blackfoot River drainage is found in Spence (1975) The Mike Horse
Mill was constructed on Mike Horse Creek in 1919 to process lead and silver. Mining and
millmg occurred intermittently through the period until about 1954 when the venture was
abandoned. During the time the mine was active, a tailings pond was gradually built on Beartrap
Creek from mill wastes (See photos). When the dam failed, approximately 100,000 tons of
pyntic tailings washed into Beartrap Creek and the upper Blackfoot River (Laird 1975) Metallic
constituents of the tails included Cadmium (Cd), Copper (Cu), Iron (Fe), Nickel (Ni), Lead (Pb)
Zmc (Zn), Gold (Au), and Silver (Ag). Fe, Pb and Zn were present in the highest concentrations'

Repairs by the Anaconda Company consisted of rebuilding the break in the dam, placement of
additional spillway capacity and refacing the dam with new gravel material. The original 24"
outlet pipe under the dam was cleared out at both ends and will continue in use. No further
repairs were made to the bypass canal since it is intended the canal will not be used in the ftiture
due to its poor condition. A new 54" concrete overflow pipe was installed through the dam to
replace the bypass canal. Changes were made to the diversion structure at the head of the pond so
that runoff water would more readily be transported into the pond instead of entering the old
bypass canal.

During dam repair, four ponds of various sizes were constructed in the Blackfoot River
floodplain downstream from the dam. The pond locations were borrow sites for material used to
repair the dam. They were designed to help improve fish habitat in this reach of the river.

METHODS

Water Ouah'ty

Water quality samples were collected at the sites listed in Table 1 and shown on Map No. 1
(Page A-71 at the end of this report. Several agencies collected samples during the period. Some
of the same sites sampled by Spence (1975) were resampled during this study.

Samples collected by all agencies except the US Geological Survey (USGS) were analyzed at the
chemistry laboratory, Department of Health and Environmental Sciences (DHES) in Helena.
Samples collected by the USGS were analyzed at their Salt Lake City, Utah laboratory.

Bottom Fauna

Bottom fauna samples were collected at two sites on October 2, 1975: (1) Blackfoot River at
Pops Place and (2) Blackfoot River at the Flesher Pass road crossing on Highway 279. These two
sites were previously sampled by Spence (1975). Three 1 -square-foot samples were collected
with a modified Waters round square foot stream bottom sampler (Waters 1961). Samples were
preserved in 70% alcohol and sorted in the Department of Fish and Game's pollution control
laboratory in Helena. Samples were identified to genera by Robert Newell, Department of Fish
and Game, Glendive, MT.

Species diversity of the bottom fauna populations before and after dam failure was determined
using Shannon- Weaver diversity indices (Shannon and Weaver 1964). Formulae for the indices
are given in Appendix A. Appendix A also shows Brillouin diversity indices, which are
modifications of Shannon- Weaver (Peilou 1969, quoted in Newell 1976a).

Live Caged Fish

Four live cages containing wild cutthroat trout were placed at four locations to measure survival.
Cages were placed at the locations listed in Table 2 and shown on Map No. 2 (Page A-72 at the
end of this report). Cage No. 4 was a control placed in Shoue Gulch (also known as Shave
Gulch), an unaffected tributary entering the Blackfoot River about one mile below the tailings
dam.

Cages were checked daily from July 9-13 and the status offish noted (re. alive and healthy, alive
but stressed, dead). Cages were removed after checking them on July 13.

Fish Populations

Electrofishing with a Fisher-Shocker, Model FS-101, powered by a 1500 watt alternator, was
conducted on July 11, 1975 to determine if a complete kill offish had occurred due to the tailings
pollution. Sampling was done in the Blackfoot River at Flesher Pass road crossing at a site
previously sampled by Spence (1975). Approximately 900 feet of stream were sampled. Prior to
this date, water was too high for adequate sampling efficiency and safety. Sampling was also
done on a 600-foot section of the Blackfoot River at Pop's Place on July 18, 1975.

A second fish sampling program was done in late September at the Flesher road site. This time a
fish population estimate was made using the method of Vincent (1974) and was compared with a

previous estimate made in early September 1973 (Spence 1975). A 2,455-foot section was
electrofished with a Smith-Root Type VI backpack shocker. The marking run was made on
September 25 and the recapture run on October 2, 1975.

Stream Sediment and Tailings Analyses

One sample of sediment that had washed downstream from the tailings dam was collected and
sent to the Montana Bureau of Mines and Geology, Butte, for metals analysis. This sample was
arbitrarily collected at a deposition zone in the Blackfoot River upstream from Shoue Gulch on
June 23, 1975. Approximately two liters of a sediment/water mixture were collected from the
upper 2-3 inches of deposited material. Laboratory results are compared with a sediment sample
collected at Pop's Place in 1973.

Two samples of the mine tailings behind the dam were collected by the Anaconda Company on
July 10, 1975 and analyzed in their laboratory in Tucson, Arizona. Results of those analyses are
given later in this report.

RESULTS

Water Quality

Analytical results of individual water quality samples taken at the sites shown in Table 1 are
given in Appendix B.

Bottom Fauna

Results of the bottom fauna collected at two stations (Pop's Place and Flesher) in October 1971
and November 1972 (before dam failure) and in October 1975 (after dam failure) are tabulated in
Table 3.

The most noticeable differences were at the Flesher station, particularly within genera which
contained large numbers of individuals before dam failure and much fewer after failure. For
example, in the order Plecoptera, the genus Alloperla contained only 67 individuals in 1 975
compared to 243 in 1971 and 336 in 1972. Similarly, the genus Bgetis, in the order
Ephemeroptera, contained six individuals in 1975 compared to 157 in 1971 and 81 in 1972. On
the other hand, some genera occurred in 1975 which had not been found in 1971 or 1972.
Overall, there was a marked reduction in numbers within individual genera in 1975 compared to
those present in 1971 and 1972. The number of genera decreased by 65.3% at Pop's Place and
65.2% at Flesher. Total numbers were 86.2% less at Pop's Place and 92.4% less at Flesher.
Numbers per square foot decreased 92.5% at Pop's Place and 86.7% at Flesher. The above
percentages were calculated using the average of 1971 and 1972 data.

Note: For reference purposes. Table 3 shows the families or genera of bottom fauna collected
during the study by Spence (1975) whether or not they were found at the stations sampled during
the current study.

Figure 1 illustrates the total numbers of bottom fauna. Figure 2 the number of bottom fauna per
square foot and Figure 3 the number of bottom fauna genera before and after failure of the
tailings dam.

A newly constructed beaver dam had flooded out the Pop's Place station sampled in 1971 and
1972. Therefore, the 1975 sample site was moved about 100 feet upstream from the previous site
and on a similar substrate type.

Species Diversity

Species diversity indices are used to analyze the structure of a biological community through the
use of information theory (Newell 1976a). In analyzing community structure, information
theorists ask how much new knowledge or "information" about species composition can be
obtained by drawing individuals at random (Newell 1976a). As sample size increases, the
diversity of the pooled samples increases rapidly at first, then levels off. Since diversity of
individual scimples is highly variable, it is preferable to report the diversity of the pooled samples
(Newell 1977).

With the Shannon- Weaver index, an index above 3.0 generally reflects a healthy, unstressed
community while an index below 1.0 indicates a monospecific community under stress. An
index range of 1 .0-3.0 seems to indicate a community under some stress (Newell 1 976a). A low
diversity index indicates a largely monotypic community dominated by a few abundant
organisms. Often the total number of species is low, suggesting that degraded environmental
conditions exist which favor the proliferation of a few tolerant species and the removal of less
tolerant ones. A high diversity index indicates a heterogeneous community in which abundance
is distributed more evenly among a number of species and the total number of species is
generally high (Newell 1977).

Theoretical maximum diversity (Dmax) exists if each individual belongs to a different species
and theoretical minimum diversity (Dmin) exists if all individuals belong to the same species.
The distribution of individuals among species lies between these extremes in most communities
■§i and diversity is intermediate. Redundancy (R) is an expression of the dominance of one or more

species and is inversely proportional to the wealth of species (Wilhm and Dorris 1968).
Redundancy is always between 0 and 1 . The numerical value for diversity (D) lies between
Dmax and Dmin and shows the actual diversity of the aquatic community as compared to the
maximum and minimum diversities which could have occurred in the given sample. When
diversity is high, redundancy is low and vice verse (Spence 1975).

Comparisons of bottom fauna diversity before and after dam failure using the Shannon-Weaver
diversity indices are shown in Table 4. The indices are based on pooling three one-square-foot
samples at Pop's Place in 1971 and 1972, four one-square-foot samples at Pop's Place in 1975
and three one-square-foot samples at Flesher in 1975. The 1971 data for Pop's Place are taken
fi-om Spence (1975), page A-86, since diversity indices had already been calculated. Diversity
indices had not been calculated by Spence (1975) for the October, 1971 samples at Flesher but
the data (See p. A-90) were used to calculate the indices after dam failure. The 1 972 Flesher
samples had not been identified when the Spence (1975) report was completed. These samples,
as well as the 1975 samples, were identified by Robert Newell after dam failure. Pooled data for
all the samples (except for 1971 at Pop's Place) are shown in Appendix C-1.

Diversity indices for each one-square-foot sample collected before and after dam failure are
shown in Table 5 and Appendix C-2)

In analyzing whether significant differences in diversity indices occur between samples. Cairns

(1967) states that "For biologically oriented readers, my own operational definition of optimal

is the ability to support an aquatic community in a pattern which does not vary more than 20
percent from the empirically estimated maximum steady-state diversity possible in each
particular locale." Newell (1976b and Appendix D) interprets this to mean that variations of up
to 20% of maximum observed diversity can be called normal and healthy but deviations over
20% are called unhealthy.

The highest diversity indices found for the pooled data at Pop's Place and Flesher for 1971 and
1972 were compared with the diversity indices at the two stations for 1975 (See Table 4). These
comparisons show a 62.2% deviation at Pop's Place and 27.6% deviation at Flesher, indicating a
signflcant difference in bottom fauna populations, particularly at Pop's Place, as a result of dam
failure.

Live Caged Fish

Results of this test are shown in Table 6. More detailed data are given in Appendix E.

The data show that the tailings pollution caused mortality in caged fish. Excluding those trout
which escaped, the percent mortality which occurred in each cage was as follows:

Cage #1 (Flesher road) 7/9 = 78%

Cage #2 (Pop's Place) 10/10 = 100%

Cage #3 (Below Pass Cr.) 7/10 = 70%

Cage #4 (Shoue Gulch) 0/6 = 0%

The specific cause of mortality (suspended sediment, metals, etc.) was not determined.
Fish Populations

The electrofishing done on July 1 1, 1975 at the Flesher station produced 27 cutthroat trout
averaging 4.9 inches long and 22 brook trout averaging 5.0 inches long. Thirty-eight (38) slimy
sculpin between 1.5-4.6 inches in length were also captured in the 900-foot section. The data
show that the dam failure did not completely eliminate the existing fish populations.

13

The Pop's Place station was similarly sampled on July 18, 1975. Seven cutthroat trout averaging
6.3 inches long and 54 brook trout averaging 4.8 inches long were captured in a 400-foot section,
again showing there was not a complete kill of trout. No sculpin were observed in the section.
However, very few sculpin were found at this location in sampling prior to dam failure (Spence
1975, p. A- 130).

The trout population estimate made in September, 1975 at the Flesher station showed that,
compared to 1973, there was a total reduction of 83% for all sizes of cutthroat trout and 77% for
brook trout after dam failure (Table 7). Most of the reduction in cutthroat occurred in the smaller
size groups (1 .5-4.9 inches). There was also a reduction in larger sizes of cutthroat. Confidence
limits are at the 80% probability level for both the 1973 and 1975 estimates. The data indicate
that cutthroat were either unsuccessful in spawning during the spring of 1 975 or there was a large
mortality of eggs and/or fry in gravels after spawning took place. There were insufficient
recaptures of marked brook trout in 1975 to estimate their numbers by separate age groups. The
reduction in total numbers was statistically significant at the 80% probability level for both
cutthroat and brook trout.

Stream Sediment and Tailings Analyses

The data presented show what metals were present in the mine tailings behind the dam and the
principal metals found in sediments in the Blackfoot River before and after dam failure.

Results of analyses of the sediment sample collected above Shoue Gulch in 1975 are given in
Appendix F. The analyses show that only small amounts of each metal were carried in
dissolved form (Table I) but high concentrations were carried in suspended form (Table IV).
Some of the water quality analyses that reported dissolved fractions showed the same results, i.e.,
only small amounts of metals were dissolved in runoff waters (See Appendix B).

Table 8 compares the metal content of sediment samples collected in the Blackfoot River before
(1973) and after (1975) dam failure. Except for Cd, higher concentrations of metals occurred in
the 1975 sediment sample than occurred in the 1973 sample. The 1975 sample was not collected
at the same site as the 1973 sample and diis may account for some of the variation. For purposes
of comparing the two samples, only the Tyler Sieve (mesh) U.S. Standard No. (-100 ) fraction is
shown in Table 8.

DISCUSSION

Water quality and biological sampling showed that the Mike Horse Dam failure adversely
effected fish and bottom fauna populations in the upper Blackfoot River, although it was not
specifically determined how these effects occurred.

A possible cause for mortality of smaller cutthroat trout is sediment deposition during the
cutthroat spawning and rearing period which prevented egg and fiy development and,
consequently, resulted in reduced numbers of young-of-the-year trout. Some other mechanism,
such as high concentrations of suspended sediment, may have been responsible for reduction in
larger ti-out of both species as well as for young-of-the-year brook trout from the 1974 fall
spawning season. Suspended sediment can cause physical damage to the fish, but some literattire
indicates that large quantities of sediment are needed to cause direct fish mortalities (Cordone
and Kelly 1961). Suspended sediment samples were not collected in 1975 but turbidity readings
were made. The highest ttirbidity recorded during the period was 5200 JTU on June 25 in

See Spence (1975), Appendix D, p. A75, Field No. 8 and Lab No. 8.
See Appendix E, Table IV (-100 fraction) in this report.

To provide as much information as possible about the
sample, I have done several things.

First, in preparing the sample for ^;^l.f,^^;,l^^'''i

estimate this to be about 80 to 9U P^J^^^ moisture
moisture the sample contained. B> ^^'I^oying xnt;
this way rather than by evaporation, I thought that we

metals in the water.

The solid phase of ^he sample was then^dried^to^.^^

The sample was divided into two segments with a J°^|5

The solid phase was chemically decomposed by a mix-

elemental measurements were made by atomic absorption spec-

The dissolved phase (the water that was extracted from
the solid phase) was also analyzed by atomic absorption
spectrophotometry .

DISCUSSION

The two samples which were taken on July 10, 1975 were received
on July 15, 1975. In order to remove the samples from their con-
tainers the tailings were slurried with water, filtered and the
solution was then measured and assayed. The wet filter cake was
v;eighed. A small portion was cut for assay and weighed both wet
and dry. This portion was also assayed. Table No I shows pre-
paration results and Tables II and III show assay results.

Horse Mine Dam eroded

by roiioff from heavy rams

Bv CARLA BECK

Tribune SUff Writer

The old Mike Horse Mine Dam, actually
a huge mound of mine tailings backing up
an old «-dimert pond, was eroded by
runoff irom a recent intense rainstorm,
sending quantities of tailings into the
headwaters of the Blackfoot River.

Formerly a White Hope Mines Inc.
property, it is now owned by Anaconda
Co. It is located in the Heddleston Mining
District, 18 miles east of Lincoln and
about three miles south of Montana
Highway 200.

According to second-hand accounts, this
is what apparently happened. During a
rainstorm the night of June 19. a landslide
blocked a diversion ditch that earned
w3ter artjund the old tailings deposit. It
also plugged an outlet for a drainage that
intercepted clean water at the head of the
pond. The water then could not go out the
normal outlets so it topped the tailings
and eroded a large channel through the
tailings.

Max Boiz of the Water Quality Bureau
of the Department of Health and En-
vironmental Sciences said Anaconda
crews have been at the site repairing the
diversion ditch and reopening the old
drainage outlet.

Frank Laird, head of environmental
engineering for .Anaconda's General Min-
ing Division. Tucson, flew by company
plane into Butte Thursday noon. He was
reponed en route to the Mike Horse area
Thursday afternoon and could not be
reached for comment. Jim Adier, Butte,
who handles all exploratory work m the
Heddleston and Stillwater, including land
mine reclamation, also could not be
reached.

An Anaconda official who did not want
his name used said his information was
sketchy at this point but that an engineer
and others were examining the area to
determine the best method of preventing
funher deterioration as well as deciding
what should be done with the material
that's been displaced.

James A. Posewitz, chief of the En-
vironment and Information Division of
the State EV^p.'inment of Fish and Game,
said he could not fault Anaconda for not
getting after the problem.

Bou said no damage assessment could
be made at this lime. He said what the
bureau fears is that the tailings, all as-
sociated with metallic mining, will react
with the water to form an acid condition
and also release to.\ic metals into the
water. He said there could be no: only the
immediate problem of suspended
material but also the Inngierm problem
due to toxicity.

"I can assure you there is substantial
stream damage due to the ruptured dam.
Ho'.i.e\er, v.'e won't know the actual de-
tails until we have the opportunity to get
in there and evaluate the stream over a
period of time. Fortunately, we have good
water quality records from the past and
records of biological conditions, so we can
compare and make a judgment. It w;ll
take several _\-ears to really under?tai')d
what effect this has had. We're hopmg the
effects won't be as bad as it looks now,"
Bot; said.

Botj !s hoping the high stream flow will
mitigate the damage somewhat. He has
sun'eyed the damage from the air and
below Landers Fork the gray tailings
could not be distinguished from the
muddy wa'er of the ruer.

"it's my opinion those tailings will go
many miles down the Black'oC'i and the
Clark Fork. A lot won't deposit in the

Potentially Toxic Tailings
Released Into Blackfoot River

LINCOLN (AP) - State au-
thorities say heavy rains on
June 19 washed away part of a
dam made of old mine tailings
and sent potentially toxic ef-
fluent into one of western Mon-
tana's most popular fishing riv-
ers.

Water-quality specialist Max
Botz of the state Department of
Health and Environmental Sci-
ences said it was not known
how much the adds storedin
the old Mike Horse Dam Had
poisoned the Blackfoot River.

The dam is located alwut 18
miles east of Lincoln.

Bot2 said he feared the tail-
ings would react with water to
form acids and to release toxic
metab.

He said the department had
kept detailed water-quality re-

cords which would help evalu-
ate the damage, but added the
assessment would take several
years to complete. '

"I can assure you there is su-
bstantial stream damage due to
the ruptured dam. ...We're hop-

ing the effects won't be as bad
as it looks now," he said.

The Anaconda Co. sent Frank
Laird, head of environmental
engineering of the General Min-
ing Division, to Butte on Thurs-
day. Laird was reported travel-

ing to the old dam later in the
day.

An Anaconda spokesman said
the firm was working on dam
repair and minimizing damage
to the popular waterway.

LINCOLN (AP) - State
authorities say heavy rains on
June 19 washed away part of a
dam made of old mine tailings
and sent potentially toxic ef-
fluent into one of western
MonUna's most popular
Bshing rivers.

Water -quality specialist Max

the old Mike Horse Dam had
poisoned the Blackfoot River.

The dam is located about 18

■ toxic metals Into solution.

"I can assure you there is

substantial stream damage
due to the ruptured dam ...
We're hoping the effects wont
be as bad as it looks now," he
said.

An Anaconda spokesman
said the firm was working on
dam repair and minimizing
damage to the popular
waterway.

Botz said the dam, formerly
owned by the White Hope
Mines, Inc., and purdiased by
Anaconda, was damaged when
torrential rains caused a
landslide which blocked
drainage outlets.

With normal channels
plugged, water began to spill
over .the top of the tailings,
eroding a large gap.

Company Says
Pollution Halted

LINCOLN (AP) - The Anaconda Co. says it has
stopped the flow of possibly toxic lead and zinc mine tail-
ings into the trout-rich Blackfoot River from an eroded

dam.

Frank Laird, Anaconda's environmental engineering
chief, said the company is evaluating the situation to pre-
vent any future recurrence of the incident.

The 50-foot-high tailings dam eroded and spilled spoils
into the river as heavy rains pounded large areas of western
MonUna. Officials said they first spotted the freed taUings

I June 20.

• "That big gash in the dam is down to bedrock, and the

! creek is just going down through there now carrying very
fine material," said Uter Spence, a state Fish and Game
Department ecologist.

"It's in those tailings where the problem is going to
" occur," Spense said, adding that cutthroat trout currently
are spawning in the upper Blackfoot River.

A potential for extensive damage to the river exists be-
cause of oiidaUon of the metals along the stream, forming
adds and toxic metals in the water, Spence said.

"When you see how bad it looks, it's hard to imagine it
won't have detrimental effects on the river," Spence said.

According to Laird, construction crews began repair-
ing the dam last Monday. The crews repaired a diversion
ditch and beadgate and were to have water totally diverted
from the dam breach last Saturday, Laird said.

"We will have to evaluate what we are going to do in
the future to prevent further channeling," Laird said.
"There are many alternatives, and they are all costly."

Laird said the Mike Horse lead and zinc mine
apparently initiated the tailings pond about 1941. The dam
rose until the mine discontinued operation about 1953, he
said. The dam is located about 18 miles east of here.

Spence said the current patchwork repairs will have to
be supplimented by a more complete solution guaranteeing
there will be no recurrence of the spillage.

"I don't know the engineering answer," Spence said,
"but anything running into that pond now is going to come
out that hole."

The ecologist called tailings ponds "timebombs that
are scattered wherever there has been mining, and which
are just sitting there waiting for circumstances to cause
something like this."
