Kleinschmidt conducted a detailed pre-design analysis to guide the final design and construction of the Lake Conestee Dam. This included a hydrologic analysis with hydraulic modeling to assess flood flows and an evaluation of nine alternatives, including a no-action option, to determine the most viable solution.

Kleinschmidt advanced the new dam project through key phases in collaboration with the Conestee Nature Preserve and the South Carolina Department of Environmental Services. Efforts included geotechnical exploration, construction permitting, NEPA review, field investigations, procurement of an owner’s project manager and engineering procurement-construction services, selection of a design-build team, oversight of the new design, and ultimately, dam construction.

With Kleinschmidt’s expertise, Otter Tail Power secured a favorable license that minimized the requirements for protection, mitigation, and enhancement measures. This achievement not only ensures a cost-effective solution for OTP’s customers but also preserves the community’s way of life by maintaining reservoir levels close to residential areas. Our tailored solutions and strategic oversight provided OTP with a clear path to license renewal, affirming our commitment to delivering results that benefit both our clients and their communities.
