Collings Lakes reports spillway repairs and temporary Lake George fixes; residents ask about refill controls
Summary
Dam committee members reported spillway and outlet-pipe repairs underway, a temporary shore-up at Lake George that reduced leakage by 60–70%, and a reopened Braddock sluice gate that refilled a recently cleaned scour hole. Residents asked how water levels will be controlled during refilling; the board said it has lowering permits and will use the sluice gate and removable boards.
Board members reported progress and setbacks on multiple dam and lake repairs at the Oct. 7 Collings Lakes meeting. Work on the spillway and outlet pipes is underway: most pipes were filled and encased in concrete, a steel wall and slopes are being formed, and compaction testing and a pending nuclear-density test are planned, the report said. The speaker noted a person opened the Braddock sluice gate unexpectedly, refilling a scour hole and requiring crews to redo cleaning before final concrete pours.
On Lake George, the board said a temporary shore-up using boards and screws reduced leakage by an estimated 60–70 percent, but permanent repairs require concept drawings, bid drawings and state approval. The board discussed coordinating with utility companies about telephone poles and overhead wires that could affect construction timing.
Resident John Harra asked how the association would measure and control lake levels when filling begins. President Steve Slimm said, “we already have the lowering permits to be able to do that,” and explained the association can open the sluice gate incrementally and remove boards across the spillway to lower water, and that downstream neighbors would be notified in an emergency.
A resident also asked whether the $153,000 figure referred to redesign costs for the Cushman spillway; the board said the amount reflected redesign work required after the state identified scour problems following heavy rain and noted a roughly $15,000 engineering bill to revise completed work.
