In an effort to mitigate the effect of woody debris on Lake Lillinonah during the recreational boating season, including the effect of the annual required Summer CCA at the Shepaug station (which usually takes place in June), FirstLight Power will be slowly raising the water surface elevation beginning on Friday, May 21st to reach approximately 198.8ft on Monday, May 24th. The elevation will vary from May 24th to May 26th while the debris is removed. We will return to normal operations on Friday, May 28th (the start of Memorial Day weekend).
