Lake Lillinonah Pond Brook Boat Launch

Lake Lillinonah (Pond Brook) Boat Launch

Newtown

September 10, 2026
Lake Lillinonah – Beginning on October 26, 2026, FirstLight will initiate 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 190.5’. The drawdown will lower lake levels to minimum pond levels and aim to return to normal operating elevations on November 4, 2026, as river conditions allow. All homeowners are encouraged to remove structures, boat lifts, and docks from Lake Lillinonah to prevent ice or flood damage from occurring during the winter months. All work planned to occur along the shoreline requires prior permitting from FirstLight, who can be contacted at www.firstlightpermits.com.

Advisory
An increased risk of a cyanobacteria bloom has made this area potentially unsafe for water contact. Cyanobacteria blooms are also known as “blue-green algae blooms” or “harmful algae blooms (HABs)”.

Be alert and avoid skin contact with water that:

Looks like spilled paint
Has surface scums or films
Is discolored or has colored streaks
Has green globs floating below the surface

Keep children and pets away from cyanobacteria blooms and rinse off any exposed skin or fur with clean water.

HYDRILLA IS RAPIDLY SPREADING THROUGHOUT CT AND HAS BEEN RECENTLY FOUND IN THIS WATERBODY. It grows quickly and forms dense patches. It can displace native plants, impact fish and wildlife habitat, and interfere with boating, paddling and fishing.

Help Stop the Spread of Hydrilla
