Draw Down Update - FirstLight issued a press release today, announcing plans to conduct a deep drawdown this winter for Candlewood Lake.
FirstLight, the owner and operator of the Rocky River Pumped Hydro Storage Station, will initiate the deep drawdown season for Candlewood Lake, which includes Squantz Pond, after November 1, 2026, as weather conditions allow. In recent years, the annual drawdown of Candlewood Lake has typically been initiated between December and February, with the exact start date determined by weather patterns and planned maintenance timelines. The trend toward warmer and wetter winter weather, widely attributed to climate change, has and may continue to push the drawdown to this later timeframe. The deep drawdown, executed in consultation with the Connecticut Department of Energy and Environmental Protection, the U.S. Fish and Wildlife Service, and the Candlewood Lake Authority, will be completed with water levels returning to normal summer operating ranges
prior to Memorial Day 2027. A deep drawdown is scheduled for this year. The normal summer operating range of the station is from 429.5’-427’, and the deep drawdown will target an elevation of 418’ with a 2’ winter operations pumping and generation range from 418-420’. Due to unknown weather patterns, exact dates and associated lake levels are not available. Homeowners are therefore strongly encouraged to remove their structures, boat lifts, and docks from Candlewood Lake prior to the winter season to prevent ice damage along the shoreline. All work planned to occur along the shoreline requires prior permitting from FirstLight, who can be contacted at http://www.firstlightpermits.com.
