Project Description
Prospect Reservoir Dam is a 45-foot-tall earthfill dam that provides approximately 6,500 acre-feet of water storage. An evaluation of the existing structure identified significant deterioration along the dam face and outlet conduit, prompting a comprehensive rehabilitation effort to address these deficiencies and support the dam’s long-term performance and reliability.
The project began with a feasibility study to evaluate repair alternatives and identify the most cost-effective solution. Engineering services included geotechnical investigations, hydrologic and hydraulic analysis, structural calculations, and preparation of bid and construction drawings, specifications, and contract documents.
Our support continued through construction with project bidding, resident inspection, quality control testing, and contract administration to help ensure the rehabilitation work was completed in accordance with project requirements.
