The Fenton River runs through Mansfield, Storrs, and Willington, as well as small parts of Windham, all but the latter in Tolland County, Connecticut spanning 18.895 miles (about 30.408 kilometers). It feeds into Mansfield Hollow reservoir at its end, making it a tributary to the Mount Hope, Natchaug, and Willimantic rivers. The Fenton River is fed by several smaller brooks, streams, and creeks.
The stone Gristmill on the intersection of Stonemill and Gurleyville roads was once functional, and now is protected by the Joshua's Tract Conservation and Historic Trust. Along its shores are huge swaths of protected land, mainly belonging to the university, Joshua's Trust, Nipmuck Trail, or other such preserve. Soil erosion is a small problem along some stretches.[1][2] The USGS has a river flow and height monitoring station posted in the Fenton on Old Turnpike Road, in Storrs.[3] It is currently not being pumped due to drought.
