The Saco River Watershed Stream Crossing Assessment Project seeks to assess all road-stream crossings (culverts) within the watershed using the New Hampshire Stream Crossing Assessment Protocol.
The Green Mountain Conservation Group collected data for over 150 stream crossings in 2020 in the towns of Effingham, Freedom and Ossipee last summer, and will continue to collect data for more than 250 stream crossings this summer in the towns of Madison, Tamworth and Sandwich.
The collected information is used to rate each culvert for its compatibility with the stream, its resistance to flooding, and its ability to allow fish and other aquatic species to pass through.
