The Great Lakes Watershed Management System (GLWMS) is an online decision support tool that allows users to estimate soil erosion, sediment loading, and nutrient runoff at watershed and field-scales. It can evaluate the impacts of land cover change and best management practices (such as no-till, cover crops, and filter strips) and store results in a database for generating cumulative reports across projects. The system was developed by the Institute of Water Research at Michigan State University (IWR-MSU), in collaboration with Purdue University and support from The Nature Conservancy and the U.S. Army Corps of Engineers. The GLWMS is currently available in the priority basins identified in the U.S. EPA’s Great Lakes Restoration Initiative (the Saginaw Bay basin of Michigan, the Maumee River basin of Ohio, the Fox River basin of Wisconsin, and the Genesee River Basin of New York). The system’s geographic availability continues to grow (the River Raisin in Michigan was recently added), as does its functionality (groundwater recharge analysis was recently added to the Saginaw Bay basin). TNC is currently using the system to help prioritize NRCS EQIP applications, and previously utilized the GLWMS models to prioritize conservation to facilitate recharge (Legge et al., 2013).

    Very useful for conservation decision making at the field level! This tool calculates environmental benefits from different conservation scenarios very rapidly Only draw back is that it’s only available in certain GL watersheds right now..
