This site is an active repository for support of the Lake Erie Ecological Model (LEEM).

The Lake Erie Ecological Model is a simulation model developed under the sponsorship of the Lake Erie Task Force of the International Joint Commission. The purpose of model development was to provide a platform for joint consideration of lake-wide effects of invasion of zebra mussels, declining phosphorus loading, continuing toxic contamination, and fish harvesting on the structure of the fish community of Lake Erie. Model development continued as part of an EPA funded project to develop multiobjective risk decision tools for assessment and management of Great Lakes ecosystems. Current work focuses on linking whole lake responses to watershed processes in a regional stressor-response modeling framework.
