Modeling tells us what may happen in particular circumstances. Modeling can often be used to make forecasts that help us prevent unwanted circumstances before they happen. Together with monitoring, these tools can tell us how we need to respond to what the lake is doing and how the lake may be responding to what we are doing.

The Lake Management Team is working to refine the ELCOM-CAEDYM model as a predictive tool for Coeur d’Alene Lake. Development of this computer model was funded through the Basin Environmental Projects Improvement Commission (BEIPC or “Basin Commission”) with a Clean Water Act grant from the United States Environmental Protection Agency.

The ELCOM-CAEDYM Model simulates processes within the lake, such as inflow of metals and nutrients and the flow of these plumes through the lake, interactions between sediment and the water, primary production, organic matter cycling within the water column, and can predict dissolved oxygen profiles that can be checked against actual data collected.
