PROJECT DESCRIPTION

The USACE Buffalo District is currently preparing a solicitation to award a contract for a project at the West Valley Demonstration Project (WVDP), in West Valley, New York. The project is being procured by the United States Army Corps of Engineers (USACE) on behalf of the United States Department of Energy (DOE).

This project will rectify deficiencies of the Lake 1 dam system to maintain a safe and reliable impoundment system for the remaining service life of the dam. The primary driver of the project is that the Lake 1 spillway has activated (conveyed water) during high frequency rainfall events regularly since the dams were constructed and, due to this, the existing turf reinforcement mat chute is severely eroded and in a state of failure. The erosion appears to be exacerbated by the constriction on the right side of the chute, which reduces the effective width of the spillway and concentrates flow toward an area where erosion has initiated several times. With each overtopping event, erosion channels on the left and right side of the spillway get closer to Lake 1. If left in its current condition, future erosion will likely compromise the Lake 1 Dam impoundment.

Repair the Lake 1 Spillway to avoid compromising the stability of the spillway and the Lake 1 Dam impoundment. The Lake 1 spillway will be rehabilitated to provide more robust performance and achieve a greatly reduced level of risk during activation periods by both hardening the spillway face with reinforced concrete and modifying the spillway’s geometry. The new slab size is approximately 70 feet wide and 18 inches thick. It is horizontal at the crest, with chute slopes at 1V:4H along the downstream side and discharges at the stream channel. Chute and baffle blocks are approximately 8 inches wide and typically attached to the slab with a single line of reinforcing near the centerline of the block, keeping minimum cover. Concrete cutoff walls are provided at the upstream and downstream ends of the spillway slab.

The spillway chute walls have footings that are about 5 feet deep below grade. Primary drainage pipes are 6-inch diameter perforated HDPE pipe running transverse under each slab construction and control joint. The transverse drainpipe is sloped at 1 percent grade from peak at centerline crown toward each side. At the sidewalls, the drainpipe transitions from perforated to solid wall and passes through the sidewall in an 8-inch diameter PVC sleeve.

A drainage stone layer is placed under the full extent of the slab and envelops the drainpipes. Stone drainage ditches are provided for the full length behind both sidewalls. A wave wash protection blanket consisting of bedding material overlaid with light stone fill will be installed along the upstream slope of the Lake 1 Dam embankment. The upstream slope protection will extend from the crest of the embankment to approximately 2.6 feet below the ordinary high water. A two-layer blanket filter was designed to be placed beneath the concrete slab spillway.
