Climate change is expected to alter stream temperature and flow regimes over the coming decades, which will in turn influence distributions of aquatic species in those freshwater ecosystems. The NorEast web portal serves as a coordinated, multi-agency regional framework to map and store stream temperature locations and data for states in New England, the Mid-Atlantic, and the Great Lakes regions. 

The tool consists of a map viewer where the public can view locations and metadata for current and historic stream temperature monitoring sites, a database where data stewards can store and manage their data, and web services to connect, communicate, and serve data for use in analysis and applications. Stream temperature monitoring locations and metadata can be viewed for more than 10,000 locations across 30 states, contributed by 40 different organizations. In the map application, users can filter information based on location and the organization overseeing the freshwater site. Organizations collecting continuous stream temperature data can request to become NorEaST users, and data stewards can use the web portal to store and manage their organization’s continuous stream temperature data.
