WESTERN LAKE ERIE ECOSYSTEM MODEL: AN OPERATIONAL MODEL FOR THE SCIENTIFIC AND MANAGEMENT COMMUNITY

Over the last five years LimnoTech has worked to develop the Western Lake Erie Ecosystem Model (WLEEM) to assist researchers and managers with answering complex questions regarding sediment and phosphorus fate and transport and connections to HABs in Western Lake Erie. This presentation will review recent applications of the model as part of the Annex 4 modeling group for the Great Lakes Water Quality Agreement, to the 2014 CSMI year for Lake Erie, and a recent confirmation of the performance of the model with 2015 conditions. The model is a powerful data integration and interpretation tool and can help managers and scientists isolate specific loading sources and identify key nutrient cycling pathways. When updated on a periodic basis the model can help to monitor lake responses to watershed nutrient reduction efforts and test new scientific hypothesis. Operational ecosystem models, such as this one, complement existing monitoring programs very well and help to reduce uncertainty for managers that must make decisions regarding ecosystem responses to specific and often costly actions.
