Monitoring tells us, the community, what is happening with water quality trends. Regular core monitoring of the lake and its tributaries allows us to better understand the dynamics of Coeur d’Alene Lake, and keep an eye out for trigger conditions that allow us to diagnose the lake’s condition and take action to improve its health.
Regular monitoring will also allow us to improve our ability to model these dynamics in the future. The Lake Management Team conducts regular water quality monitoring of the lake seven to eight times every year. This information is summarized in Monitoring Reports.
Monitoring in tributaries also helps us identify opportunities for on-the-ground projects that may help reduce nutrient inputs to the lake and help maintain good water quality. Nutrient source inventories vary from year to year, according to our focus areas. Check out our Projects page to learn about activities going on throughout the basin.

Special studies help us answer specific questions the about lake. Currently, we are looking at nutrients and metals in rooted aquatic plants, macroinvertebrates (small animals without backbones that can be seen with the naked eye) on the lakebed, and picoplankton (tiny microorganisms in the lake). We hope to gain more insight into potential pathways for nutrients and metals to enter the water, their impacts on lake ecology, and to develop improved indicators of lake productivity.
