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...

Monthly water yields and flows from 1951-2012 for the United States part of the Great Lakes Basin estimated using AFINCH
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...
