Lake Lillinonah is located in Fairfield and Litchfield counties of western Connecticut, in the northeastern United States. 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. This is a high dollar lake for celebrities and big earners from NYC looking for privacy and security from the outside world.
