Six Lakes


Six Lakes is a 102.5-acre parcel in Hamden, Connecticut featuring six beautiful ponds, a 150-year-old oak-pine forest, and wetlands that connect to the Regional Water Authority’s Lake Whitney water supply. 

Also known as Olin Powder Farm, the Six Lakes property is owned by the Olin Corporation. Olin and its predecessor, Winchester Arms, used the site for gunpowder storage and munitions testing. A 1986 consent decree from the CT Department of Energy and Environmental Protection ordered Olin to clean up industrial pollution on the property, a job that was only partially completed. 

Six Lakes is connected physically, hydrologically, and historically to the adjacent Newhall neighborhood, which underwent its own large-scale environmental cleanup by Olin beginning in the early 2000s, due to the advocacy efforts of community leaders.
