Carbon WCD Scofield Dam Outlet Modifications

Project Overview

VanCon rehabilitated and modified the existing Scofield Dam by replacing the concrete crib wall, retaining wall, zone backfill material, and embankments. The top of the outlet and concrete spillway were redesigned and replaced with new concrete. The outlet floor and the walkway across the spillway were redesigned and replaced. VanCon designed and installed concrete slabs to address water spray from the outlet as well as a pedestrian access to the upstream staff gauge in the reservoir basin. Rock was removed from behind the existing rock slope wire mesh and the mesh was repaired at the top with rebar supports.
