| Abstract/Description or Keywords | This report assesses the water quality of seven tributaries to Okanagan Lake on the west shore, near Westbank. Provisional water quality objectives are set to protect aquatic life and wildlife, irrigation and livestock watering, and drinking water supplies in Peachland, Trepanier and Westbank Creeks. In the other four tributaries, objectives are not set but monitoring programs are recommended so that objectives can be considered in the future. The most serious water contamination in the area arises from the Brenda Mines operation which can affect both the Trepanier and Peachland Creek watersheds. Mining ceased in early 1990, although the mill continues to process ore stockpiles. The company is working on post-abandonment plans to maximize environmental protection. Characteristics of most concern for the future related to this operation are molybdenum, sodium, and total dissolved solids. Provisional water quality objectives set for Westbank Creek will likely not be achieved on a consistent basis until the discharge from the Westbank sewage treatment plant is discontinued to the creek or the treatment facilities are upgraded. Attainment of the water quality objectives will protect human health as far as recreation is concerned at nearby beaches on Okanagan Lake as well as protect aquatic life while allowing other uses of these waters. |
