The Columbia River Basin: Issues and Driving Forces within the Columbia River Basin with the Potential to Affect Future Transboundary Water Management
This master’s thesis uses modelling to investigate the impacts of management decisions at the Duncan Dam on populations of kokanee salmon in the lower Duncan River. Includes CRT mandated parameters into management models that impact kokanee salmon population dynamics.
Completed as a Research Project for a Masters of Resource Management at Simon Fraser University.
“The Duncan Dam Project, British Columbia, falls under the direction of a water use plan. One provision under the current plan is to investigate the effects of facility operations on kokanee salmon (Oncorhynchus nerka). With the limited data set available, I developed a closed-loop simulation procedure, which uses a relationship between minimum winter flows and egg-to-fry survival to simulate kokanee population dynamics. This population is then controlled by management decisions (minimum yearly winter flows). The model acts to provide a framework
to answer questions regarding flow requirements and the conservation and non-conservation consequences of flow management within a water-controlled system. Future investigations into stock distinction, flow-survival relationships, yearly escapement estimates, and biological characteristics specific to the Lower Duncan River kokanee are required if this model is to be directly applied to the Duncan System.” (Taken from abstract)
