Kilton Pond Dam Work

The New Hampshire Department of Environmental Services Dam Bureau will start repairing and upgrading the Kilton Pond Dam this year. You can view the Aerial of the Dam work here, and the Kilton Pond Wetlands permit here.

**UPDATE 3/29/23**NHDES will be starting the drawdown of Kilton Pond on April 10th. This drawdown should last 3 to 4 weeks but they will be working to get it in as soon as they can and raise the pond to normal summertime level.

**UPDATE 7/18/2023** Due to the heavy rains, The Dam Bureau had to pull the plug on the dam to let some water out. You may notice the water lowering some, but they will be putting the plug back in on Thursday, July 20, 2023 and then the water levels will be restored. 

**UPDATE 7/25/2023** The Dam Bureau will be pulling a 6-inch log from the drain which will cause the water level to lower slightly. This is to help with the overflow that all the rain has caused. 

**UPDATE 3/5/2024**Received from Dam Bureau - "in two weeks or there about we will be drawing down Kilton Pond in Grafton to complete the final repairs and removal of the temporary cofferdam in accordance with the Wetlands and Non-Site-Specific Permit #2022-00933 (see attached).  We will begin lowering the pond following Ice Out or shortly there after at a rate of no more than 6 inches per day.  Upon removal of the cofferdam the pond will be refilled at a rate retaining no more 10% of the inflow into the pond and allowing 90% of the inflow downstream."
