Natchaug River
The Natchaug River is a 17.5 mile-long tributary of the Shetucket River that runs through eastern Connecticut. Originally used by Native Americans for freshwater fishing, the river played an important role in the development of the textile industry in the 19th century. Today, the river is used primarily for recreation, including fishing, canoeing, and hiking. The river is fed by several small tributaries and is home to a variety of fish and wildlife, including trout and bald eagles. The river flows through several reservoirs, including the Mansfield Hollow Reservoir, which was constructed in the 1950s to provide drinking water to the nearby town of Mansfield. There are also several dams along the river, which provide hydroelectric power and regulate water flow. The Natchaug River is an important natural resource in the region, providing both recreational and agricultural opportunities.
