| Abstract/Description or Keywords |
This report assesses the water quality of Thompson River. The report has two parts : an overview report and a technical report. The reports summarize the water quality of the mainstem Thompson River and to propose water quality objectives which would protect existing and future water uses. The geographic limits of the study include the South Thompson River and its tributaries between Little Shuswap Lake and the confluence with the Notrth Thompson at Kamloops, the North Thompson downstream from McClure and the lower Thompson River to its confluence with the Fraser River including Kamloops Lake. The study area Figure 1. does not include three watersheds tributary to the lower Thompson which are the subject of past or future water quality studies (the Bonaparte, Deadman and Nicola Rivers). Designated water uses throughout the drainage basin include protection of aquatic life, irrigation, livestock watering and wildlife water supply, recreation and industrial water supply. In general, the water quality of the mainstem Thompson is relatively good although there have been, in some cases, significant impacts from municipal or industrial discharges as well as from non-point inputs. Water uses have been identified and water quality objectives set for characteristics such as microbial indicators, colour, chlorinated organics and resin acids in various reaches of the Thompson to provide a basis for future water quality protection and management.
