Power & Renewable Energy HYDROELECTRIC DAM SPILLWAY EXPANSION > Projects > Hydroelectric Dam Spillway Expansion A 90-year old hydroelectric dam receives much-needed upgrades to allow for more discharge capacity and reduce local flooding. INSIDE THE PROJECT Kokosing Industrial used its broad-based hydropower construction experience to expand the spillway for an existing dam. Kokosing installed cofferdams, six piers and five slide gates. This unique project also included rehabilitation of the spillway facing concrete and rock anchor stabilization. Kokosing Industrial provided cost savings to the client early by pricing the project with a land-based approach, opposed to the original and more costly water-based design. WHY IT MATTERS Though it was not a flood control dam, this project was part of the licensing agreement with the Federal Energy Regulatory Commission which allowed for more water to flow through in the event of a major flood. Kokosing’s land-based approach to expanding this nearly century-old dam delivered the project over 10 months early and significantly under budget compared to the original water-based design. Close
