A Dam Safety Assurance Mega Project: A Dam Safety Assurance (DSA) report was approved in 1998 to address deficiencies that could lead to a breach of the project. A breach would cause catastrophic flooding along the largest river valleys in West Virginia that include the capital city of Charleston and major manufacturing and chemical industries. Dam failure could put 165,000 lives at risk and result in property damages in excess of $20B. Investments approved by a 1998 Dam Safety Assurance (DSA) (Phases 1-4) study have increased confidence in the dam’s ability to store water to its original design elevation (El 1520). The DSA work, now underway, primarily consists of increasing outflow capacity with an auxiliary spillway and stabilizing the dam with rock anchors and thrust block. This work is anticipated to be completed in 2019. To learn more about the DSA please expand the Dam Safety Assurance Mega Project folder to the right.

New Investment Being Designed: Since the approval of the 1998 DSA report, an additional concern has been identified. The primary spillway cannot pass significant flow without substantially increasing the potential for a breach of the dam. A supplementary study has been completed to identify a selected plan to address this additional deficiency. This study is The Design of Phase 5 is underway and should be advertised in 2019. For more information on this proposed investment, please expand the Proposed Phase 5 Investment folder.
Your Flood Risks: Bluestone Dam, like all dams, reduces the risk of flooding but does not eliminate it. Extreme storms can exceed Bluestone Dam’s ability to slow storm water requiring releases. In addition, storms can occur downstream of Bluestone Dam or along the multitude of uncontrolled streams in the New and Kanawha River valleys, including the Greenbrier River, the Meadow River, the Lower Gauley, Paint Creek, Cabin Creek and the Coal River that can cause flooding.
The U.S. Army Corps of Engineers works diligently to ensure our dams work to reduce flood risks; but we cannot eliminate them. If you live in a river valley, regardless if there is dam, your life and property are at risk of flooding. To learn more about your flood risks and what you can do to reduce them, please expand the Flood Risk Awareness folder and visit www.FloodSmart.gov.
