Dam Tentative Schedule

For re-installation of the upstream valve-
Divers are tentatively schedule to be here the week of May 9th. At that time they will install a machined flange onto the 'thimble' protruding from the dam wall some 50 feet below the surface. An underwater curing epoxy will be used between the flange and the thimble to take up and seal any imperfections. The machined flat face of the flange will face outward for mating with the valve. This epoxy may take 7 to 10 days to cure depending upon water temperature.
Therefore the actual re-installation of the valve is scheduled for May 24/25th.

For work on the spillway-
Three options are under evaluation:
1. Enlarge the existing spillway
2. Add a second spillway
3. Raise the height of the dam
The goal in each case is to prevent the water from a PMF (Possible Maximum Flood), defined as 38 inches of rain in a 72 hour period from topping the dam. That is a lot of water, but there have been local occurrences of this much rain in the Commonwealth!
At present we are negotiating with the Department of Environmental Protection, Division of Dam Safety, which way would be in everyones best interest to peruse. Once this process is completed, a schedule for the actual work will be developed.
