Project Description

The Brooklyn Dam Project was originally constructed in the 1930’s and was owned and maintained through the years by the Groveton Paper Company.  It was washed out in the 1960’s and was gutted and later served only as a flood control dam.  In 2015, the project completed redevelopment with installation of two new turbines within the existing project works which included the existing 120-ft long, 14-ft high spillway dam, floodgate structure, and powerhouse.
