*** ALERT NOTIFICATIONS ***PUBLIC NOTICE & PRESS RELEASE
Kemmerer Reservoir Water Level Reduction and Safety Advisory Kemmerer–Diamondville Water & Wastewater Joint Powers Board (JPB) City of Kemmerer, Wyoming Release Date: March 23, 2026 The Kemmerer–Diamondville Water & Wastewater Joint Powers Board (JPB), in coordination with the Wyoming State Dam Safety Engineer’s Office, is issuing this public notice regarding required operational changes at the Kemmerer No. 1 Reservoir. Reason for Action A recent inspection conducted by the Wyoming State Dam Safety Engineer identified structural deficiencies in the primary (principal) spillway. As a result, the State has mandated that no water flow over the primary spillway until necessary repairs can be completed. To comply with this directive, the dam must be operated using the low-level outlet works only. In addition, the State has issued a Storage Restriction Order for:
Planned Reservoir Drawdown Beginning Monday, March 23, 2026, the JPB will begin lowering the water level in the reservoir. This action is being taken:
The goal is to create sufficient storage capacity (buffer) to prevent water from reaching and flowing over the primary spillway, even during higher seasonal inflows. Due to hydraulic limitations, even with both 30-inch low-level outlets fully open, there may not be enough discharge capacity to keep the reservoir below the spillway without first lowering the overall water level. Public Safety Advisory – Ice Conditions At this time, the reservoir remains ice-covered. Lowering the water level beneath the ice creates unstable and highly dangerous conditions. ⚠️ The public is strongly advised:
Ongoing Operations and What to Expect
Commitment to Safety and Reliability The JPB recognizes the importance of this action for:
Lowering the reservoir and modifying operations ensures the dam continues to function safely while addressing the identified spillway concerns. Public Cooperation and Updates The JPB appreciates the cooperation and understanding of:
