Document Description
The purpose of the project is to structurally modify Stony Gorge Dam by correcting inadequate lateral support of the concrete buttresses and to stabilize the foundation below the spillway in Stony Creek. The Stony Gorge Dam will be modified by installing a diaphragm wall and constructing additional struts between the buttresses. The spillway foundation will be stabilized by dewatering the erosion hole that has formed, excavating rock, installing anchor bars and placing a concrete slab on the upstream face of the erosion hole. The hole is approximately 100 to 120 feet wide and extends about 100 feet downstream from the spillway apron. The depth of the hole varies and is about 30 feet at its deepest.
