Description of Work U.S. Geological Survey (USGS) will expand the online availability of geospatial data to monitor the presence and extent of invasive species in wetlands, coastal areas and other sensitive habitats. USGS is working with the Great Lakes Observing System collaboration and other data sharing efforts across the Great Lakes to compile the data into a user friendly format that is accessible on line. Elevation data will be expanded in the Great Lakes Basin using a collaborative to support the GLRI. This information would support invasive species monitoring, wetland inventory, and habitat restoration. USGS will work with the Great Lakes Observing System and other data sharing efforts to make USGS geospatial...

Description of Work The first major goal of this project is to characterize and evaluate the extent to which contaminants of emerging concern (CECs) threaten fish and other wildlife in the Great Lakes. This includes identifying and characterizing CECs in the Great Lakes Basin, identifying risk-based screening concentrations for priority CECs, evaluating population-relevant effects of complex mixtures on biota, and identifying the Great Lakes waterways at greatest risk. The second major goal of this project is to pilot and develop a short-term and an ongoing long-term state-of-the-art bioeffects surveillance program for the Great Lakes basin. This includes developing strategies which will account for variable conditions...

Description of Work U.S. Geological Survey (USGS) will develop and provide forecasting tools for managers to determine how water withdrawals or other hydrologic or land use changes in watersheds may affect Great Lakes ecosystems. This information will help guide restoration efforts to achieve maximum effectiveness and success. Project provides unified information across the Great Lakes Basin for ecosystem restoration, assessment, and management by incorporating models that relate changes in landscape and hydrologic variables and stresses to changes in ecosystem function. The project relies upon regionally consistent hydrologic, biologic, and geospatial data to generate regionally consistent estimates, models, and...

Description of Work The Great Lakes Restoration Initiative (GLRI) was established to accelerate ecosystem restoration in the Great Lakes by confronting the most serious threats to the region, such as nonpoint source pollution, toxic sediments, and invasive species. Three Priority Watersheds have been targeted by the Regional Working Group's Phosphorus Reduction Work Group (Fox/Green Bay, Saginaw, and Maumee) and are characterized by having a high density of agricultural land use and have ecosystem impairments that have been clearly identified. Within the Maumee River Priority Watersheds, monitoring is being conducted at the sub-watershed, edge-of-field, and subsurface-tile scale. The edge-of-field and subsurface-tile...

Monthly water yields for 105,829 catchments and corresponding flows for 107,691 stream segments were estimated for water years 1951-2012 in the United States part of the Great Lakes Basin. Estimates were computed using the AFINCH (Analysis of Flows In Networks of CHannels) application within the NHDPlus geospatial data framework. AFINCH provides an environment to develop constrained regression models to integrate monthly streamflow and water-use data with monthly climatic data and fixed basin characteristics data available within NHDPlus or supplied by the user. Monthly flow time series for individual stream segments can be retrieved and used to approximate monthly flow duration characteristics and to identify possible...
