Charles L. Turner Reservoir Dam
Siler City, North Carolina
In order to address Siler City’s continuing water supply needs, the city hired Thalle to construct a dam that would create a reservoir of some 160 acres. The ensuing dam was 26 feet high with a 300 foot spillway. In constructing the dam Thalle placed 12,100 cubic yards of roller compacted concrete (RCC), 30,000 tons of offsite aggregated, 5,000 tons of onsite boulders and riprap and 221 tons of steel. In doing so, Thalle employed over 40 workers for a total of 86,000 man hours and deployed 240 pieces of equipment, to include two concrete mixing plants, two pugmills and a variety of other heavy equipment. The project was completed on time in early 2009 for a cost of approximately $11,000,000.

Blalock Dam & Reservoir
Spartanburg, South Carolina
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.

Boyd's Corner Dam Reconstruction
Kent, New York
For the New York City Department of Environmental Protection, Thalle Construction modified and reconstructed a 100-year old masonry dam and its outlet facilities. This dam is one of the initial reservoirs of the Greater New York water supply system. It's reconstruction required grouting and post-tensioning in addition to extensive concrete work and bridge construction. To enable water to flow toward outlet facilities, Thalle installed new valves, gates, piping, and instrumentation. Because sustaining the natural habitat at the dam was a fundamental concern, Thalle applied water flow temperature controls to maintain a suitable environment for marine biology.
