Water Quality Assessment of the Salmon River at Salmon Arm 1985-24 EXECUTIVE SUMMARY The Salmon River at Salmon Arm is located in the southern-interior portion of the province. Its headwaters originate about 15 km northeast from Salmon Lake. Some of the river's flow is diverted into Salmon Lake; much of that flow returns to the river via McInnis Creek, the outlet from Salmon Lake. From the confluence with McInnis Creek, the Salmon River flows northeast to Falkland, then southeast and east to Glenemma, and finally north to Salmon Arm before entering Shuswap Lake. The total length and drainage area of the Salmon River are approximately 12 km and 151 km 2, respectively. The Salmon River is an important tributary of Shuswap Lake, which drains into the South Thompson River. In addition to supporting anadromous salmonids, resident fish species and other aquatic organisms, the Salmon River and its tributaries provide important sources of raw water for domestic water supplies, irrigation, and livestock watering. Recreation and aesthetics also represent important uses of the aquatic environment, both of which generate social and economic benefits to area residents. Concerns related to environmental quality conditions in the Salmon River are primarily associated with non-point source contaminant discharges. Such contaminants arise from a variety of land use activities, including forest management, agriculture and urban development. Contaminants of concern in the watershed include suspended solids, turbidity, ammonia, phosphorus, nitrogen, metals and fecal coliforms. In addition, water withdrawals from the river and nearby infiltration galleries have resulted in decreased stream flows and associated effects on water temperatures and other habitat features in the river. CONCLUSIONS Flows fluctuate throughout the year, but peak in the May-June period on a yearly basis. Low flows seem to be consistent through most of the other months of the year.

Water Quality Assessment of the Salmon River at Salmon Arm 1985-24 Water temperatures and dissolved oxygen often exceed water quality objectives, especially during the hot summer periods. Several metals exceeded guidelines or water quality objectives on occasion; however, these seemed to be correlated with turbidity and were likely in particulate form and not biologically available. Such metals included: aluminum, cobalt, chromium, copper, iron, lead, silver, and zinc. Cadmium also often exceeded guidelines, and was not always related to turbidity, which means that it could potentially be more available to aquatic life. This has just become evident over the past couple of years since the cadmium detection limit has decreased; cadmium will continue to be monitored at these low levels to track this potential concern. Colour values and fecal coliforms and E. Coli often exceeded guidelines for drinking water at the source; however, these were related to turbidity events and complete treatment of the source water would be needed prior to use for drinking. Arsenic values may be showing a slight increase in concentration through the period of record. This may be due to a larger groundwater contribution to the flow. Lithium and extractable silicon were showing distinct decreases in concentrations over time. RECOMMENDATIONS We recommend monitoring be continued for the Salmon River at Salmon Arm to track the possible increases in variables, and guideline exceedences that have been identified in this report. Either trivalent and hexavalent forms of chromium should be measured in the future, or alternately, guidelines be developed for total chromium values. A statistical analysis of the data for arsenic, lithium, and silicon should be conducted to confirm whether the identified trends are real.

Water Quality Assessment of the Salmon River at Salmon Arm 1985-24 Water quality indicators that are important for future monitoring are: flow, water temperature, specific conductivity, ph, turbidity, hardness, and dissolved oxygen, appropriate forms of metals for comparison to their respective guidelines, and other variables related to drinking water such as colour, fecal coliforms and E. Coli. Canada British Columbia Water Quality Monitoring Agreement iii

Water Quality Assessment of the Salmon River at Salmon Arm 1985-24 Introduction The Salmon River, near Salmon Arm B.C., is located in the southern-interior portion of the province (Figure 1). Its headwaters originate in the vicinity of Tahaetkun and Bouleau Mountains, south of Westwold and northeast of Merritt. The river's headwaters are located in Monte Hills Provincial Forest, some 15 km northeast from Salmon Lake. Some of the river's flow is diverted into Salmon Lake; much of that flow returns to the river via McInnis Creek, the outlet from Salmon Lake. From the confluence with McInnis Creek, the Salmon River flows northeast to Falkland, then southeast and east to Glenemma, and finally north to Salmon Arm before entering Shuswap Lake. The total length and drainage area of the Salmon River are approximately 12 km and 151 km 2, respectively. The Salmon River is an important tributary of Shuswap Lake, which drains into the South Thompson River. In addition to supporting anadromous salmonids, resident fish species and other aquatic organisms, the Salmon River and its tributaries provide important sources of raw water for domestic water supplies, irrigation, and livestock watering. Recreation and aesthetics also represent important uses of the aquatic environment, both of which generate social and economic benefits to area residents. Concerns related to environmental quality conditions in the Salmon River are primarily associated with non-point source contaminant discharges. Such contaminants arise from a variety of land use activities, including forest management, agriculture and urban development. Contaminants of concern in the watershed include suspended solids, turbidity, ammonia, phosphorus, nitrogen, metals and fecal coliforms. In addition, water withdrawals from the river and nearby infiltration galleries have resulted in decreased stream flows and associated effects on water temperatures and other habitat features in the river.

Water Quality Assessment of the Salmon River at Salmon Arm 1985-24 FIGURE 1: Salmon River at Salmon Arm This report discusses water quality data collected by the provincial and federal governments between 1985 and 24 from a station on Salmon River near its mouth at Salmon Arm. Data for the Salmon River at Salmon Arm have been collected on a frequency of about once every two weeks. As well, twice per year, two additional samples are collected in order to ensure that there are two periods when weekly samples are collected during five consecutive weeks. In addition, quality assurance samples (blanks and replicates) are collected six times per year. Canada British Columbia Water Quality Monitoring Agreement 2
Water Quality Assessment of the Salmon River at Salmon Arm 1985-24 The federal data are stored under ENVIRODAT station number BC8LE4 and the BC Environment station E2692. The water quality variables are plotted in Figures 3 to 79. Water Survey of Canada operates a flow gauge at the same site (site number BC8LE21). Flow data from 1911 to 24 are graphed in Figure 2. FIGURE 2: Water Survey of Canada Flow Data for Salmon River near Salmon Arm WATER QUALITY ASSESSMENT The state of the water quality was assessed by comparing the values to B.C.'s approved and working guidelines for water quality (B.C. Ministry of Environment, Lands and Parks, 21), and by looking for any obvious trends in the data. Any levels or apparent trends that were found to be deleterious or potentially deleterious to sensitive water uses, including drinking water, aquatic life, wildlife, recreation, irrigation, and livestock watering were noted in the following variable-by-variable discussion. Canada British Columbia Water Quality Monitoring Agreement 3
Water Quality Assessment of the Salmon River at Salmon Arm 1985-24 The following water quality indicators are not discussed as they met all water quality guidelines and showed no clearly visible trends: phenolphthalein alkalinity, ammonia, barium, bromide, nitrite, total nitrogen, fixed non-filterable residue, fixed filterable residue, non-filterable residue, extractable silicon, and tin. The following water quality indicators seemed to fluctuate through the year according to turbidity concentrations, but were below guideline values and had no other trends: antimony, beryllium, bismuth, dissolved organic carbon, gallium, lanthanum, manganese, nickel, total phosphorus, rubidium, thallium, and vanadium. Other water quality indicators seemed to fluctuate through the year according to the specific conductivity of the water. For dissolved forms of many of these indicators, they would be a part of the measured conductivity, and this is to be expected. These types of indicators that were not measured above guideline values included: alkalinity, ammonia, boron, dissolved inorganic carbon, calcium, chloride, potassium, magnesium, molybdenum, nitrate, total dissolved nitrogen, ph, sodium, hardness, strontium, sulphate, and uranium. Flows (Figure 2): fluctuate throughout the year, but peak in the May-June period on a yearly basis. Mean flows throughout the year are about 2 m 3 /s; although mean peak flows are about 2 m 3 /s. Absolute peak flows have been as high as 6 m 3 /s. Aluminum (Figure 3): values exceed the drinking water guideline; however, values have fluctuated with turbidity, are likely in particulate form, and not biologically available. There does not appear to be any trend in values during the period of record. Arsenic (Figure 8): values have been below guidelines but seem to be increasing in value during the period of record. When we used a linear regression, we found that there was a weak correlation of values increasing through time (R 2 =.5). Total arsenic values also seem to increase with turbidity, meaning that higher values are likely in particulate form and not biologically available. Canada British Columbia Water Quality Monitoring Agreement 4
Water Quality Assessment of the Salmon River at Salmon Arm 1985-24 Cadmium (Figures 18 and 19): values seemed to fluctuate with turbidity, which means that higher values would be associated with particulate matter and would likely not be biologically available. Although values seem to be getting lower through the period of record, this is likely more a phenomenon related to decreasing detection limits and improved analytical capabilities through time, rather than a real decrease in concentration. Lower cadmium values, and their detection limits, during the 23-24 period also coincided with lower turbidity concentrations. Additional data need to be collected to determine whether turbidity and cadmium are in fact beginning to decline. Cyanide (Figure 21): values generally were well below the maximum and 3-day average guidelines for weak-acid dissociable cyanide. One exception was a total cyanide value in October 24. Since data for only one year have been collected, additional sampling is required before any trends might become evident. Cobalt (Figure 22): values seemed to be correlated with turbidity, which means that higher cobalt values are associated with particulate matter and not likely biologically available. The occasional individual value has exceeded the BC guideline of 4 µg/l for the 3-day mean concentration; however, all individual values were well below the guideline for maximum concentrations of 11 µg/l. Lower cobalt values in 23-24 coincided with lower turbidity concentrations. Additional data need to be collected to determine whether turbidity and cobalt are in fact beginning to decline. Colour: apparent colour (Figure 23) values from 1988 until 1998 seemed to fluctuate with turbidity and regularly exceeded the drinking water guideline of 15 TCU for true colour; however, this is to be expected since true colour is measured on a filtered sample (i.e., turbidity removed). True colour values (Figure 24) began to be measured in 1997 and were lower than apparent colour values, as expected; however, values seem to fluctuate with turbidity and regularly exceeded the drinking water guideline. Chromium (Figure 25): values in the 199 s exceeded the guideline for trivalent chromium and hexavalent chromium; however, since the year 2, only the guideline for hexavalent chromium has been exceeded. Values seem to fluctuate with turbidity Canada British Columbia Water Quality Monitoring Agreement 5
Water Quality Assessment of the Salmon River at Salmon Arm 1985-24 values, meaning that the higher chromium values are likely in particulate form and not biologically available. There is a very weak trend identified using a linear regression (R 2 =.17) of decreasing concentrations through time; however, this is likely related to lower turbidity concentrations in the post-2 period. We recommend that either trivalent and hexavalent forms of chromium be measured in the future or guidelines be developed for total chromium values. Copper (Figures 26 and 27): values generally met the guidelines (hardness-dependent) for maximum and 3-day mean concentrations; however, when these were exceeded, turbidity values were also high. This mean that the higher copper values are in particulate form and not likely biologically available. Higher values in the late 198 s were quite high due to widespread contamination because of the failure of preservative vial cap liners between 1986 and 1991. E. Coli (Figure 28) and Fecal Coliforms (Figure 31): regularly exceeded the water quality guideline and short and long-term water quality objectives, respectively, for drinking water sources. High fecal coliforms seem to be correlated with high turbidity concentrations. Drinking water taken form the Salmon River would require complete treatment. Fluoride (Figure 29): values were measured only between 1988 and 1999. Values generally met the aquatic life guideline of.3 µg/l. High fluoride values coincided with periods of high specific conductivity and low river flows, suggesting that the fluoride was a result of groundwater contributions to the base flow of the river. Iron (Figure 3): values regularly exceeded the guideline for the protection of aquatic life and drinking water supplies (aesthetics) of 3 µg/l. High iron values were correlated with high turbidity concentrations, meaning that the iron was in particulate form and not biologically available. It would also be removed in water treatment processes for drinking water supplies. Peak iron values since 2 seem to be lower than during the previous decade; however, these lower values are likely the result of lower turbidity values during that period. Canada British Columbia Water Quality Monitoring Agreement 6
Water Quality Assessment of the Salmon River at Salmon Arm 1985-24 Hardness (Figure 33): values were strongly correlated with specific conductivity and low river flows, suggesting that the hardness was a result of groundwater contributions to the base flow of the river. Values throughout the year were generally higher than the 1 mg/l level for drinking water supplies. Lead (Figure 36): values seem to correlate with turbidity, meaning that high lead values are in particulate form and not likely biologically available. Values were generally below all guidelines for aquatic life and drinking water supplies, with only two individual values exceeding the lowest BC 3-day mean guideline of 4.5 µg/l. Analytical detection limits for lead were reduced in 23 from the.2 µg/l level, which means that in future years, trends to lower values might be suspected; however, the lower detection limits may be responsible for such observations. Lithium (Figure 37): values have shown a strong decline during the period of record (R 2 =.31) but have always been below the BC guideline to protect aquatic life of 67 µg/l. Values also seem to be correlated with high specific conductivity and low flows, meaning that the lower values are likely associated with a groundwater contribution to base river flow. Dissolved Oxygen (Figure 48): values seem to fluctuate with conductivity, which is not surprising in that conductivity peaks occur when there are low flows in the colder months of the year, and under normal situations, dissolved oxygen concentrations rise at colder temperatures. Only one value was slightly below the 8 mg/l water quality objective. Selenium (Figure 56): values on occasion exceeded the guideline to protect aquatic life of 1 µg/l. Selenium values seemed to be correlated with specific conductivity with highest values occurring during low flow conditions. Silica and Silicon (Figure 58): Values for extractable silicon have decreased considerably over the period from 1999 until 22, with a linear regression having a R 2 value of.23. Canada British Columbia Water Quality Monitoring Agreement 7
Water Quality Assessment of the Salmon River at Salmon Arm 1985-24 Silver (Figures 59 and 6): values on occasion exceeded the BC aquatic life guideline of.1 µg/l, but this usually happened when detection limits were at that level. The detection limit for silver was reduced to.1 µg/l in early 23, and no values have exceeded the guideline since that time. Data from that latter period seem to fluctuate with turbidity concentrations, meaning that the higher silver values are related to particulate and not likely biologically available. Water Temperature (Figure 65): varies with flow and the time of year. Temperatures have exceeded objective levels especially during the hot summer periods. Zinc (Figures 71 and 72): values fluctuate with turbidity, which means that high values are associated with particulate matter and not likely biologically available. Occasional values exceed aquatic life guidelines that are hardness-dependent. Canada British Columbia Water Quality Monitoring Agreement 8
