This project seeks to move towards development of a coordinated, multi-agency regional stream temperature framework and database for New England (ME, VT, NH, CT, RI, MA) and the Great Lakes States (MN, WI, IL, MI, IN, OH, PA, NY) by first compiling metadata about existing stream temperature monitoring locations and networks; developing a web-based decision support mapper to display, integrate, and share that information; building a community of contacts with interest in this effort; and developing data portal capabilities that integrate stream temperature data from several data sources.
