The Three Rivers Local Protection Project is located in the village of Three Rivers in the town of Palmer. The project is situated at the confluence of the Ware, Quaboag, and Chicopee rivers.
In conjunction with the Barre Falls and Conant Brook dams, the project provides a high degree of flood protection to 55 acres of residential, industrial, commercial, and public land in Three Rivers.
Construction started in January 1964 and was completed in May 1966 at a cost of $2.1 million. Palmer operates and maintains the project.
The project involved deepening and widening 5,200 total feet of channel in the Ware, Quaboag, and Chicopee rivers; removing the Bridge Street Bridge and replacing it with a new bridge; removing a small dam; and modifying the Main Street Bridge and the existing railroad bridge.
