The Great Lakes Watershed Management System (GLWMS) is an on-line tool that allows users to evaluate non-point source (NPS) pollution model estimates at watershed and field scales. The system links two water quality models, High Impact Targeting (HIT) from the Institute of Water Research at Michigan State University, and the Long Term Hydrologic Impact Assessment (L-THIA) from Purdue University's Department of Agricultural and Biological Engineering. HIT estimates sediment loading from agricultural lands to nearby streams; L-THIA estimates run-off volumes and pollutant loads.

This version of the system has been tailored for a pilot Pay for Performance project in the River Raisin Watershed. The sediment and nutrient analyses of HIT and L-THIA have been removed, and will be replaced by phosphorus reduction estimates from a Soil and Water Assessment Tool (SWAT) model generated by the Water Center at the University of Michigan. This tailored version of the GLWMS currently allows users to digitize fields and save them in projects. Those field boundaries will be sent to the Water Center to evaluate phosphorus reduction options and potential payments for performance.

The Great Lakes Watershed Management System represents the integration of several water quality modeling projects across the region, led by The Nature Conservancy (TNC), The U.S. Army Corps of Engineers Chicago District (USACE), the Institute of Water Research at Michigan State University (IWR-MSU), and the Department of Agricultural and Biological Engineering at Purdue University (ABE-Purdue).

This version of the system has been tailored for a Pay for Performance Project in the River Raisin Watershed. In this initial phase of that project, users can digitize field boundaries and save them to their account. Those boundaries will then be shared with the Water Center at the University of Michigan to estimate potential phosphorus reductions from various land management scenarios, and calculate potential payments for performance.

You can access the full version of the GLWMS here.
