Impact of land use on dissolved nutrient levels in four tributaries of the Fraser River, BC: Silverdale Creek, Willband Creek, Clayburn Creek and Nathan Creek
Abstract
The Fraser River basin in British Columbia is a diverse ecosystem that comprises approximately 220,000 km2. The Fraser River flows 1,370 km beginning at its headwaters in the Rocky Mountains and then discharging into the Georgia Strait near Vancouver. The Fraser River basin is unique as it has diverse geological terrain, limited damming, and experiences a wide range of precipitation and climate. The Fraser River also plays a crucial role in salmon migration. The study and analysis of water quality is imperative for protecting aquatic ecosystems and human use of the Fraser River and its tributaries. The water quality of the Fraser River is at risk from point and non-point source pollution due to population pressures. This study will focus on four Fraser River tributaries found in areas of extensive agriculture and hobby farming, residential housing, and a diverse array of industries. Land uses will be categorized using a geographic information system to capture and analyze satellite data. Dissolved nutrients are key in analyzing water quality and changes in loads can impact ecosystem functions. Dissolved nutrients (silicate, phosphate, nitrate/nitrite, and ammonium) will be examined and related to land use.
