Ecosystem Impact‐Nutrient Enrichment by Kokanee in Williston

Williston Reservoir and its tributaries are highly nutrient‐limited. Previous attempts to increase productivity through fertilization had only limited success. The introduction of Kokanee, however, has the potential to greatly change nutrient dynamics. From 1990 to 1998, over 3,000,000 Kokanee were stocked into rivers that flow into Williston Reservoir. Aerial counts a decade later showed major runs in the Finlay, Ingenika, Omineca, Ossilinka, and Germanson Rivers.
