| Abstract/Description or Keywords |
This report provides water quality data analyses for Thompson River at Spences Bridge. The Thompson River drains over 55,000 km2 of the Interior Plateau, Shuswap Highlands, and Columbia Mountains to the Fraser River at Lytton. The river is important for fish spawning and rearing, for migrating salmon, and for irrigation, livestock watering, drinking water, and recreation such as rafting and steelhead fishing. Main influences on water quality include treated effluent from a bleached kraft pulp mill and the City of Kamloops wastewater treatment plant discharge upstream from Kamloops Lake. Other small point sources include the Merritt, Clinton, Cache Creek and Ashcroft wastewater treatment plant discharges. There are several large mines in the watershed, but only small amounts of seepage are ischarged. There are also non-point source discharges from agriculture, urban development, forestry, transportation and stream bank erosion. No long-term water quality trends were identified.
