Ashuelot Pond Dam Update
The following report outlines the progress to date on the temporary

Ashuelot Pond Dam Update
The new dam gate is in and functioning as it should! Opened for the
traditional 3 foot drawdown, yesterday. Still a bit of concrete work to
be done, but that can wait until spring. That does not affect the
operation of the gate.

Ashuelot Pond Dam Update
The structure that holds the gate is being installed, this week. The plan is to install the gate, right after the structure is complete. Installation is the beginning of next week, if all goes as planned. In case you were wondering how the divers stay warm. Water is pumped, from the lake, to a heating unit. It is then pumped back to the divers wet suits, keeping them warm.

Ashuelot Pond Dam Update
Update on the dam gate as provided by Joshua Watson of M&K
commercial diving:
The concrete came out excellent in my opinion. Nice flat surface, zero
voids and good square edges. The formed opening is square and level,
the exception being the ceiling which was not poured.
The current opening is 56.75 wide by roughly 35'' in height. The frame work is about 50% complete at this time. The steel plate has been ordered today along with the I-beam for the uprights that will go to surface. Final gate dimensions will be 64'' wide by 42'' high. The gate will also have horizontal and longitudinal strong backs of .5x1.5 welded in place.
Steel for the gate should be delivered to our shop on Monday. The Thanksgiving Holiday will slow us a bit for this week, but we plan on installing the structure the following week. We have a little form work and overpour to clean up on the inside once dewatered. We believe we should be able to begin a draw down if needed by the week of the 28th. I will provide as-builts of the steel structure.

Dam Gate Update: Work is continuing under water. Building forms to hold concrete. Hope to pour, on Friday. If you look closely at the first photo, you can barely see the diver’s helmet, beneath the water.

Ashuelot Pond Dam Update
Good news. The long awaited gate work has begun. Equipment was delivered yesterday and underwater work has begun, for the new gate, at the dam. Putting in anchors for the concrete, which will be poured next week. All this work is done underwater, by commercial divers. No need to drop the lake, at this point. After the gate is completed, the plan is to do the traditional 3 foot drawdown.

Ashuelot Pond Dam Update
Dam/spillway/gate update. We now have a contract, in place, to replace the gate. Start date is about the 17th of October. Cost is $64,000+. We are going to apply for FEMA funds, but they have not yet opened for applications. No drawdown needed to do the work. The underwater work will be done by divers. After completion of the work.( Barring any issues) the usual 3 foot seasonal drawdown will occur.

Gate Update
-
We are NOT waiting on the approval of any Dam reconstruction permits at this time.
-
Before a permanent gate can be installed, the gate house requires repairs. IMPORTANT. The gate house is NOT the wooden structure/shed that contains the gate. The gate house is the concrete structure, in the water, that contains the gate.
-
The gate house is scheduled to be repaired in the first two weeks of October 2022. A temporary gate will be installed during this process. This work can be done without impacting the water level of the lake. After construction, NH Dams, LLC will file an amendment to the current wetlands permit as required by the state.
Draw Down Update
-
We should be able to safely operate the temporary gate to complete a draw down in October after the gate house is repaired. This will likely happen later than usual (i.e., after Columbus Day). This is tentatively scheduled to be a 2–3 foot draw-down.
Next Steps
-
After the temporary gate is installed, NH Dams, LLC will collect required data for the state, and NH Dams, LLC will work to move forward with the installation of a permanent aluminum gate with a manual actuator.
-
We are working to change the dam hazard classification level. This change will allow APDVD to qualify for potential state and federal funding for future projects. NH Dams, LLC will pursue this funding.
-
Next steps include the installation of a permanent gate and the completion of the dam crest.
