F26 Kootenay Lake Nutrient Restoration Program – North Arm
This ongoing restoration program addresses nutrient losses in Kootenay Lake resulting from the construction of Duncan Dam.
In this bottom-up approach, the addition of nutrients—nitrogen and phosphorus in the form of liquid agricultural-grade fertilizer—from April to September supports phytoplankton populations that are suitable for the production of daphnia, a main food source for kokanee.
This project also includes monitoring of several trophic levels as well as data analysis and reporting.
