Project Abstract

The Salmon River watershed is located in the lower Frasier River valley of British Columbia. The total length and drainage area of the Salmon River are approximately 120 km and 1510 km2, respectively. As the name would suggest, the early settlers found the Salmon River and surrounding waterways an abundant source of salmon. Unfortunately, extensive fish harvesting eventually led to the extinction of the Salmon River's pink and chum salmon stocks. The Salmon River remains, however, the most productive stream in the Lower Fraser Valley for coho and for cutthroat trout. Steelhead and at least 12 other fish species, including the rare and endangered Salish Sucker, make their home in the Salmon. The lower Salmon River and associated Fort Langley floodplains have also been an important migratory wetland for wildfowl.

The Salmon River Watershed was selected in early as 1980 for special study in regard to Salmonid Enhancement. The Salmon was identified as being one of the few remaining productive systems in the Lower Fraser Valley but as being on the "leading edge" of urban and agricultural development and thus in danger of significant habitat degradation. The watershed has undergone significant land use changes over the past 50 years, moving towards more and smaller farms and larger urban developments. This project aims to quantify these land use changes to identify "hot spots" that have a greater potential for affecting water quality in the Salmon River.
