Blalock Dam

Blalock Dam

Thalle rehabilitated Blalock Dam and Reservoir to provide additional storage of water for the City of Spartanburg.

The project included overlaying the existing earthen dam with a layer of roller compacted concrete (RCC), upgrading the existing spillway by furnishing and installing three hydraulically operated spillway crest gates and constructing a new concrete ogee crest. In addition, a bridge across the spillway was built and a new sluice gate was installed at the intake structure. The contract also required extensive clearing around the perimeter of the reservoir to accommodate higher water levels.
