2023 Extended Drawdown Status
Happy New Year!
As you likely know, the town of Hopkinton started an extended drawdown of the lake water level in October. Unfortunately, the extended drawdown has not reached its intended goal of dropping the level to 8’ below the normal lake level (as measured at the dam). Much of this is due to the late start to the drawdown and the very wet fall weather we have experienced.
In addition, the mild winter temperatures have not helped in stunting the expected weed growth. The Hopkinton DPW has informed us that they will begin closing the gate at the dam on or about January 15th. You should see the water level on the lake begin to rise shortly thereafter.
If you have any questions, please feel free to reach out and we will answer them the best that we can. Thank you to all of those that have been sharing pictures of the extended drawdown on Facebook. It is a great way for us to document the extended drawdown of 2023.
