United States Ladies and Gentlemen: Saskatchewan Environment and Resource Management Regina, Saskatchewan. Canada Herein is the 22nd Annual Report of the Poplar River Bilateral Monitoring Committee. This report discusses the Committee activities of 2002 and presents the proposed schedule for the year 2003. During 2002. the Poplar River Bilateral Monitoring Committee continued to fulfil the responsibilities assigned by the governments under the Poplar River Cooperative Monitoring Arrangement dated September 23. 1980. Through exchange of Diplomatic Notes in March 1987. July 1992. July 1997, and March 2002. the Arrangement was extended. The Monitoring Committee Arrangement is currently extended to March 2007. The enclosed report summarizes current water-quality conditions and compares them to guidelines for specific parameter values that were developed by the International Joint Commission under the 1977 Reference from Canada and the United States. After evaluation of the monitoring information for 2002. the Committee finds that the measured conditions meet the recommended objectives. The Committee notes that the flow-weighted concentration of total dissolved solids in streamflow in the East Poplar River at the International Boundary remains close to the long-term objective of 1.000 milligrams per litre, but did not exceed the objective in 2002. Based on IJC recommendations, the United States was entitled to an on-demand release of 617 dam' (500 acre-feet) from Cookson Reservoir in 2002. Montana requested the release be made during May 1-31. 2002. A volume of 542 dam (439 acre-feet) was delivered to the United States during this period. In addition. dail\ flows in 2002 met or exceeded the minmtum flow recommended by the IJC. During 2002. monitoring continued in accordance with Technical Monitoring Schedules outlined in the 1992 Annual Report of the Poplar River Bilateral Monitoring Committee. Yours sincerely.

For the March to October period, the long-term average of flow- weighted concentrations should be 2.5 mg/L or less for boron, and 1000 mg/L or less for TDS in the East Poplar River at the International Boundary. For the period prior to 1982. three-month moving flow-weighted concentration (FWC) for boron and total dissolved solids (TDS) was calculated solely from monthly monitoring results. Since the beginning of 1982. the USGS has monitored specific conductance daily in the East Poplar River at the International Boundary, making it possible to derive boron and TDS concentration using a linear regression relationship with specific conductance. Thus, the three-month FWC for boron and TDS for the period 1982 to 2002 was calculated from both the results of monthly monitoring (water-quality samples collected by both Canada and the United States) and the statistical analysis of daily specific 10 conductance readings collected by the USGS. During some years, estimated monthly water-quality sample data may be used in order to complete regression calculations of 3-month and 5-year flow- weighted concentrations. Estimated monthly water-quality samples are based upon concentration data from neighboring water-quality samples and specific-conductance data on the date of the missing water- quality sample (or date midway between neighboring water-quality sample). The Bilateral Monitoring Committee adopted the approach that, for the purpose of comparison with the proposed IJC long-term objectives, the boron and TDS data are best plotted as a five-year moving FWC which is advanced one month at a time. Prior to 1988, long-term averages were calculated for a five-year period in which 2.5 years preceded and 2.5 years followed each plotted point. Beginning in 1988, the FWC was calculated from the five-year period preceding each plotted point. For example, the FWC for December 2002 is calculated from data generated over the period December 1995 to December 2002. The calculations are based on the results of samples collected throughout the year, and are not restricted to only those collected during the months bracketing the period of irrigation (March to October) each year. 3.2.5.1 Total Dissolved Solids TDS is inversely related to streamflow at the International Boundary station. During periods of high runoff such as spring freshet. TDS decreases as the proportion of streamflow derived from ground water decreases. Conversely, during times of low streamflow (late summer, winter) the contribution of ground water to streamflow is proportionally greater. Because ground water has a higher ionic strength than the surface water entering the river, the TDS of the stream increases markedly during low flow conditions. TDS water-quality sample data collected by Environment Canada and the USGS in 2002 are shown in Figure 3.4. There were seven water-quality samples obtained this year with TDS concentrations ranging from 702 mg/L on April 18 to 1.080 mg/L on June 13. The proposed short-term objective for TDS is 1 .500 mg/L. The three-month moving FWC for TDS for the period of record is presented in Figure 3.5. The TDS 11 Figure 3.4: IDS Concentration for 2002 Water-Quality Samples from East Poplar Ri\«r at International Boundary Q 400 ♦ 1005 Figure 3.5; Three-Month Moving Flow-Weighted TDS Concentration for East Poplar Ri\«r at International Boundary 1600 1400 --J 1200 E Short- Term Objective ■ Water-quality sample derived data Regression derived data ^ ^ j^ ^ ^ y& ^ ^ ^ ^'^ ^f& ^ j& V V V V V Y ^" V ■^" ^^^^^,.Tr^^^^^^^ 12 objectives have not been exceeded during the period of record. On inspection of the plot in Figure 3.5, it is apparent that the three-month moving FWC increased gradually, year by year, up until the spring runoff of 1997, when an exceptionally heavy snowmelt contributed sufficient water of low ionic strength to the river and the reservoir to dilute the accumulated salts built up in the system. Dissolved-solids concentrations were slightly lower in 2002 relative to those recorded in 2001; however, low spring runoff and higher contribution from ground water have kept the TDS level close to the long-term objective of 1.000 mg/L. The five-year moving FWC for TDS (Figure 3.6) did not exceed the long-term objective of 1.000 mg/L in 2002. The maximum monthly value calculated in 2002 was about 943 mg/L. which is slightly less than the previous year maximum monthly value of 948 mg/L. The daily TDS values, as generated by linear regression from the daily specific-conductance readings, from January 1990 through December 2002 are shown in Figure 3.7. The data show an abrupt drop in TDS corresponding to the snowmelt runoff occurring during the spring of each year. The relationship between TDS and specific conductance applied to data collected from 1974 to 2002 is as follows: TDS = (0.62518 x specific conductance) + 34.202 (R- = 0.84. n = 605) 13 Figure 3.6: Fi\e-Year Moving Flow-Weighted TDS Concentration for East Poplar Ri\«r at International Boundary Figure 3.7: Daily TDS Concentration. 1990 through 2002: East Poplar Ri\^r at International Boundary (regression-deri\«d data) 14 3.2.5.2 Boron Boron water-quality sample data collected by Environment Canada and the USGS in 2002 at the East Poplar River at International Boundary are shown in Figure 3.8. There were seven water-quality samples obtained this year with boron concentrations ranging from 1.28 mg/L on May 28 to 2.06 mg/L on June 13. The three-month moving FWC for boron for the period of record is shown in Figure 3.9. The short-term objective of 3.5 mg/L has not been exceeded over the period 1975 to 2002. It can be seen that the data derived from water-quality samples and that derived from regression with specific conductance are similar, with the highs and lows in some degree of correspondence. This suggests that the regression generation of boron and TDS values is. in general terms, a valid procedure despite problems which arise from attempting to generate representative concentration and flow data for an entire month, based on a limited number of samples. The five-year moving FWC for boron displayed in Figure 3.10 remained well below the long-term objective of 2.5 mg/L. From mid- 1993 to the end of the data period there is a gradual decrease in the computed boron concentrations. Boron concentrations are not as well-correlated with specific conductance as TDS. Boron is a relatively minor ion. and does not in itself contribute to a large degree to the total load of dissolved constituents in the water. Accordingly, it appears likely that the standard deviation of dissolved boron (relative to the long-term mean boron concentration) may be greater than that of the major cations (sodium, potassium, and magnesium) and anions (sulphate, bicarbonate, and chloride) around their respective long-term mean concentrations. Daily boron concentrations for the period January 1990 through December 2002 are shown in Figure 3.11. The relationship between boron and specific conductance applied to data collected from 1974 to 2002 is as follows: boron = (0.00129 x specific conductance) - 0.0434 (R- = 0.58, n = 605) 15 Figure 3.8:.

The table shows the number of samples collected for each parameter and the number of times over the course of the year that the objectives were exceeded. In the table, multiple replicate samples collected during the annual quality control exercise are treated as a single sample, but where an objective was exceeded in a replicate sample, this is charged against the single sample noted. As the table shows, all parameters were within the appropriate objectives. 18 Table 3.1 Recommended Water-Quality Objectives and Excursions, 2002 Sampling Program, East Poplar River at International Boundary (units in mg/L, except as otherwise noted) Parameter Objective No. of Samples Excursions USA Canada Objectives recommended by IJC to Governments 11 Boron, dissolved 3.5/2.5(1) 6 6 0 1 Total Dissolved Solids 1.500/1.000(1) 6 6 0 II Objectives recommended by Poplar River Board to the IJC Cadmium, total 0.0012 2 6 0 Fluoride, dissolved 1.5 6 6 0 Lead, total 0.03 2 6 0 Nitrate 10.0 6 6 0 Oxygen, dissolved 4.0/5.0 (2) 6 6 0 Sodium adsorption ratio 10.0 6 5 0 Sulphate, dissolved 800.0 6 6 0 Zinc, total 0.03 1 6 0 Water temperature (Celsius) 30.0 (3) 6 6 0 pH (pH units) 6.5 (4) 6 6 0 ( 1 ) Three-month average ol flow-weighted concentrations should be <.V5 mg/L boron and <1 .500 mg/L TDS.

The supplementary water supply project currently consists of 21 wells with a total of 10 discharge points. No wells were added or deleted from the well field during the year. The majority of ground-water production in 2002 occurred during the fall to spring period. This is a typical operational pattern for the project and is done to minimize water losses. However, pumping was maintained through the 2002 summer period due to low spring runoff. In 2002. ground-water production decreased to 4.927 dam' from the 2001 total of 5.307 dam total. Production from 1991 to 2002 has now averaged 5.040 dam' per vear. Prior to 1991. the wells used for supplementary supply were part of a dewatering network for coal-mining operations. This resulted in the high production levels experienced in the early to mid 1980's. With the drought of the late 1980's and early 1990's. it was evident that there was a continued need for ground water to supplement water levels in Cookson Reservoir. Consequently the wells were taken over by SaskPower for use as a supplementary supply.

This approval was extended by Sask Water in 1996. Future revisions to the approval will likely include conditions requiring termination of pumping (with the exception of wells supplying domestic users) when the reservoir is above a specified level. In addition to the supplementary supply, SaskPower also operates the Soil Salinity Project, which is located south of Morrison Dam. The project was initiated in 1989 to alleviate soil salinity which had developed below the dam. The salinity project consists of a network of production wells which discharge into the cooling water canal, which in turn discharges to Cookson Reservoir. Operation of the salinity project continued in 2002 with production of 631 dam of ground water. This was much lower than the 2001 production level of 819 dam . and substantially lower than the average annual production of 880 dam^/year since the project inception in 1990. Production remains below optimal levels due to ongoing mechanical problems in the production wells with only PW 87104 being in service at year's end. An ongoing well rehabilitation program is expected to restore production to the levels achieved in the early 1990's. Approximately 65 percent of the total volume pumped came from wells PW87103 and PW87104 which are located on the east side of the river and the remainder was produced from PW90109 and PW90108 on the west side of the river. 21 Poplar River Power Station - Salinity Project 1000 2 900 I 800 a 0 700 3 o c 600 •D |- 500 3 a. 1 400 3 > 300 200 100 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 Year Figure 3.13 Pumpage from Salinity Control Project 3.3.2 Ground- Water Monitoring 3.3.2.1 Saskatchewan In 1996 nineteen new piezometers were installed in the Hart Coal Seam and a further eighteen piezometers from the Frenchman aquifer testing program were added to the supplementary supply monitoring network that year. With these extensive additions, no new piezometers have been added to the monitoring network since that time. Currently, about 180 piezometers are monitored as part of this project. Figure 3.14 shows the drawdown contours in the Hart Coal seam aquifer as of December 2002. Note that the 1 -metre drawdown contour extends less than 1 kilometer south of the International Boundary. There have not been significant changes in the cone of depression over the past several years, suggesting 22 that the system has approached a semi-equilibrium condition. Consequently, only minor drawdown fluctuations in response to climatic and production variations are expected. The goal of the Salinity Project is to lower ground-water levels in the Empress sands below Morrison Dam to approximately pre-reservoir levels. This is equivalent to roughly two to three metres of drawdown, and was achieved by the end of 1995 and again by the end of 1996. However, reduced production over the past several years and increased recharge from higher reservoir levels and precipitation has led to a significant contraction in the project's cone of depression. Figure 3.15 shows the cone of depression in the Empress Sands as of December 2002. Under the current operational situation, the project is clearly falling short of its goal to lower ground-water levels along the East Poplar River between Morrison Dam and the International Boundary. SaskPower has undertaken a comprehensive evaluation of their entire piezometer network (including water level and water-quality piezometers). This evaluation involved compilation of geologic and hydrogeologic data and a computer model of the area. SaskPower has asked the Saskatchewan Watershed Authority and Saskatchewan Environment to review the study. It is their hope that they can reduce their current monitoring levels from approximately 450 piezometers to about 150 piezometers. 23 Figure 3.14 Drawdown for Hart Seam Aquifer as of December 2002 24 Figure 3.15 Cone of Depression in the Empress Sands Due to the Salinity Control Project as of December 2002 25 3.3.2.2 Montana Water-levels in monitoring wells (6, 7, 9. 13. 16. 17. 19. and 22) that penetrate the Fort Union Formation and/or Hart Coal Seam were rising during 1997 and 1998. and have leveled off or decreased during the last four years (1999 to 2002).

The two 300-megawatt coal-fired units generated 4,456.200 gross megawatt hours (MWh) of electricity. The average capacity factors for Units No. 1 and 2 were 80.1 percent and 86.7 percent, respectively. The capacity factors are based on the maximum generating rating of 305 MW/h for both Unit No.l and Unit No. 2. Similar to other years, scheduled maintenance was completed in the spring and fall of 2002. Monitoring information collected in both Canada and the United States during 2002 was exchanged in the spring of 2003. In general, the sampling locations, frequency of collection, and parameters met the requirements identified in the 2002 Technical Monitoring Schedules set forth in the 2001 annual report. The recorded volume of the Poplar River at International Boundary from March 1 to May 31. 2002 was 3,960 dam (3,210 acre-feet). Based on International Joint Commission (IJC) recom- mendations and the assumption that the recorded flow is the natural flow, the United States was entitled to a minimum discharge on the East Poplar River of 0.028 cubic metres per second (m Vs) (1.0 cubic feet per second (ft7s)) for the period June 1. 2002 to August 31, 2002 and 0.028 m /s (1.0 ftVs) for the period September 1. 2002 to May 31, 2003. The minimum flow of 0.028 mVs (1.0 ft /s) for the period January 1 to May 31. 2002 had previously been determined on the basis of the Poplar River flow volume for March 1 to May 31. 2001. Daily flows in 2002 met or exceeded the minimum flow recommended by the IJC. In addition to the minimum flow, the IJC apportionment recommendation entitles the United States to an on-demand release to be delivered on the East Poplar River during the twelve-month period commencing June 1. Based on the runoff volume of 4,390 dam (3.880 acre-feet) recorded at the Poplar River at International Boundary gauging station for March 1 through May 31. 2001, the United States was entitled to an additional release of 617 dam (500 acre-feet) from Cookson Reservoir during the succeeding twelve-month period commencing June 1. 2001. Montana requested this release to be made between May 1 and May 31. 2002. A volume of 542 dam (439 acre-feet), in addition to the minimum flow, was delivered during this period. The 2002 five-year total dissolved solids (TDS) flow-weighted concentrations were below the long-term objective of 1,000 milligrams per litre (mg/L). The maximum monthly value calculated in 2002 was 943 mg/L, which was less than in 2001. Boron concentrations for 2002 continued to remain well below the long-term objective of 2.5 mg/L.

The structure of the Committee responsible for ensuring the exchange takes place is described in the Poplar River Cooperative Monitoring Arrangement. The monitoring locations and parameters listed herein have been reviewed by the Poplar River Bilateral Monitoring Committee and represent the basic technical information needed to identify any definitive changes in water quantity, water-quality and air quality at the International Boundary. The Schedule was initially submitted to Governments for approval as an attachment to the 1981 report to Governments. Changes in the sampling locations and parameters may be made by Governments based on the recommendations of the Committee. Significant additional information is being collected by agencies on both sides of the International Boundary, primarily for project management or basin-wide baseline data purposes. This additional information is usually available upon request from the collecting agency and forms part of the pool of technical information which may be drawn upon by Governments for specific study purposes. Examples of additional information are water quantity, water-quality, ground-water and air quality data collected at points in the Poplar River basin not of direct concern to the Committee.
