Winter drawdown of Thompson Lake will commence on September 8th in preparation of the dam rehabilitation project. Typically the drawdown begins the day after Columbus Day. The drawdown is necessary for the installation of the cofferdam that is going to be placed on the upstream side of the dam and for the safety of the workers performing the work. Lake levels will be no lower than what lake residents have BECOME ACCUSTOMED TO SEEING during the winter months (since 2012). The drawdown will be gradual and take some time to complete. The maximum drop for lake levels during the winter months is 38”. The level will eventually drop to 32”-33” from the benchmark line drawn at the top of the dam. These water levels were established several years ago due to the collaborative efforts of the TLEA, the town and the Maine Department of Inland  Fisheries & Wildlife. To put this in perspective, summer water levels are normally 16” below the benchmark line on the dam.
