Beginning on November 2, 2020 FirstLight will conduct a drawdown
of Lake Lillinonah at the Shepaug Dam to conduct its annual maintenance and inspection
activities. The normal summer operating range of the station is from
200’-195.5’ and the drawdown will target an elevation of 191’. The drawdown
will lower lake levels to minimum pond levels and return to normal operating
elevations on November 13, 2020.
All homeowners are urged to remove
structures, boat lifts, and docks from Lake Lillinonah to prevent ice or flood
damage from occurring during the winter months. Any and all work planned to
occur along the shoreline requires prior permitting from FirstLight.
