Bear Swamp Generating Station or Jack Cockwell Station is a pumped-storage hydroelectric underground power station that straddles the Deerfield River in Rowe and Florida, Massachusetts. It is one of many hydroelectric facilities along the river, giving that waterway the nickname of "the hardest working river in the county". An underground visitor' center provides an automated slide show and other information about the history of the project and its site. More than 60,000 guests visit this location each year.
