A number of other dams have been built on the river since European settlement, usually to power mills and other industry. A few, such as in Collinsville, are still mostly intact. The Collinsville Renewable Energy Promotion Act (H.R. 316;113th Congress) would instruct the Federal Energy Regulatory Commission to issue licenses to the town of Canton, Connecticut to restart two small power dams along the river. The bill passed the United States House of Representatives on February 12, 2013, but has not yet become law.
