Annual draw-down of lake begins

Posted October 11, 2017Manchaug Pond Foundation Waterlevel

After a beautiful summer with continually optimal water-levels contributing to safe recreation and healthy fisheries and the broader lake ecosystem, the annual winter draw-down of Manchaug Pond’s water-level begins.

Yesterday the dam caretaker decided to open the low-level gate, just a few inches he reports this morning, to slowly start the draw-down process letting out of Stevens Pond as well. He relates a recordable drop will show in about a week, with the water-level dropping an inch or two per day after that. By early January the lake will reach an anticipated low of between 4.5 and 6 feet.

We entered October just 10 inches below full with the water loss due to evaporation and lack of rain but came up a couple inches over this past holiday weekend through rain and runoff. Last year at this time the lake was 13 inches, and the year before down 8 inches, below the full mark.

Please be aware of this process making adjustments/arrangements for docks and boats along the shoreline to accommodate the reduced water level. Public access through the state boat ramp continues to be available with the draw-down but boaters should be aware of Manchaug Pond’s shallow, rocky characteristic.

Special thanks to the Town of Sutton for the commendable work managing the waterlevel and dam.

  1. Will they be drawing down more this year to help control the spreading of weeds? This type of weed control has been very effective in the history of the lake.

      Yes! Good observation! Manchaug Pond Foundation has requested we get back to the deeper historic draw-down level in order to achieve more control of the invasives. The last few years the new dam caretaker has kept the water-level higher during the winter months. He is most willing to work with us and has a good track record of bringing up the level and maintaining through the spring and summer months so re-fill should not be a problem. Winter draw-down is the most cost-efficient and easiest method of control for the exotic invasives we have but the Weed Watcher/Aquatic Plant and Water Quality Committees are looking at other factors and bringing various options to the Board of Directors for consideration. Thank you Lance!
