A Great Lakes Aquatic GAP is being conducted for riverine systems in Wisconsin. The USGS is working with the Wisconsin Department of Natural Resources (WNDR) and other cooperators to develop an ecological stream classification for Wisconsin streams and develop a database for fish species distributions and community data. The ecological stream classification is being developed based on physical characteristics that describe stream geology, geomorphology, temperature, and flow using a valley segment classification approach.
