Lake Lillinonah is a manmade lake located in Fairfield, Litchfield and New Haven counties of Western Connecticut, approximately 97 km northeast of New York City. It is the second largest lake in Connecticut, smaller only than Candlewood Lake. The lake is bordered by six towns: Brookfield, Bridgewater, Newtown, New Milford, Roxbury, and Southbury. It was formed in 1955 by impoundment of the Housatonic River and the Shepaug River by the Shepaug Dam which was built by the Connecticut Light and Power Company.
