Abstract:
The University of the Fraser Valley has undertaken the time series sampling of water chemistry of the Fraser River at Fort Langley, British Columbia and five Fraser Valley tributary creeks as a member of the Global Rivers Observatory (GRO,
www.globalrivers.org) which is coordinated by Woods Hole Oceanographic Institutionand Woods Hole Research Center. Kanaka Creek (Maple Ridge), Silverdale Creek (Mission), Clayburn Creek, Willband Creek and Nathan Creek (Abbotsford) have been sampled as part of the GRO. The creeks have been sampled for nutrient concentrations (silicate, phosphate, nitrate/nitrite, and ammonium), major ions and water chemistry parameters, such as dissolved oxygen, temperature, conductivity, pH, and turbidity monthly over the past four years. Each of these salmon bearing creeks is being threatened by anthropogenic activity (agricultural, industrial and residential development) that is occurring in the watersheds. Nathan and Willband Creeks are being threatened by agricultural activity, while Kanaka, Clayburn and Silverdale Creeks are being threatened by residential developments. Understanding these changes and their seasonal variations is crucial in assisting in protecting the natural habitat of these watersheds and streams.
