This report summarizes 2013 results from the 22nd year of nitrogen and phosphorus additions
to the North Arm of Kootenay Lake and 10th year of nitrogen additions to the South Arm. The
program was conducted using an adaptive management approach in an effort to restore lake

The primary objective of this program is to restore kokanee (Onchorhynchus nerka) populations,
which are the primary food source for Gerrard rainbow trout (Oncorhynchus mykiss) and bull
trout (Salvelinus confluentus).
Kootenay Lake is a warm, monomictic lake with a water renewal time of approximately two
years. It is 395 km2 in area with an average depth of 94 metres and a maximum depth of 154
metres. Surface water temperatures are typically warmest in August. The lake is well
oxygenated from the surface to bottom depths at all stations throughout the year.
