  All watercourses named "River" are listed here, as well as other streams which are either subject to the New Hampshire Comprehensive Shoreland Protection Act or are more than 10 miles long. New Hampshire rivers and streams qualify for state shoreland protection if they are fourth-order or larger water bodies, based on the Strahler method of stream order classification.
