This 24.8 MW, run-of-river Facility is located on the Merrimack River in the City of Lowell, Massachusetts. The Facility includes a 1,093 foot-long, 15 foot-high stone-masonry gravity dam that impounds a 720 acre reservoir and maintains a normal maximum water surface elevation of 92.2 ft NVGD 1929. The project includes a primary powerhouse and four power stations in mill buildings along the downtown canal system. The Facility received its FERC License (#2790) on April 13, 1983, and commenced operations in 1986. Upstream and downstream fish passage facilities include a fish elevator and downstream fish bypass at the E.L. Field powerhouse, and a vertical-slot fish ladder at the Pawtucket Dam. All fish passage facilities were designed in consultation with the U.S. Fish and Wildlife Service. Passage operations are supervised by the state and federal fishery agencies. The project maintains a minimum flow of 1,990 cfs by operating the project in run-of-river mode using pond level control at the E.L. Field powerhouse. Flow control and habitat enhancement are provided by a pneumatic crest gate which is due to be completed by the end of 2017.
