Survey of contaminants in suspended sediment and water in the Fraser River basin

In response to increasing public concern over the effects of growing urbanization and industry in the Fraser River Basin, in June 1991, the federal government announced the Fraser River Action Plan (FRAP). [...] As part of FIL4P, the Environmental Quality Program is responsible for providing a baseline of the environmental conditions in the aquatic environment and measuring the effects of major pollution sources on the aquatic environment. [...] The Fraser River study region encompassed the mainstem of the Fraser River between Shelley and Yale, while the Thompson River study region encompassed the area between McLure on the North Thompson River and Savona on the Thompson River. [...] The main tributaries entering the Fraser River north of Prince George are the McGregor River, draining the Rocky Mountains, the Salmon River flowing from the north and the Willow and Bowron Rivers, draining the Cariboo Mountains. [...] At Lytton the muddy waters of the Fraser are joined from the east by the clear waters of the Thompson River before entering into the long, narrow, Fraser River Canyon that cuts through the barrier of the Coast Range 03.
