Hydropower generation halted at Narrows Dam for rack repairs

Since hydropower generation was halted at Narrows Dam’s powerhouse on Dec. 20, the U.S. Army of Corps of Engineers has been releasing water from Lake Greeson through flood control valves.

Vicksburg, Miss. – The U.S. Army Corps of Engineers, during recent maintenance activities on the trash racks at Narrows Dam at Lake Greeson identified a need for repairs to the metal structure supporting the trash racks. Trash racks are metal grates preventing large debris from entering and damaging the turbans used for creating hydropower, and do not affect the integrity or effectiveness of Narrows Dam.

As a precautionary measure, Narrows Dam has halted hydropower generation until repairs are completed. This cessation will not impact the ability to carry out flood control or other missions of the Narrows Dam/Lake Greeson Project. Water releases will be executed through the flood control structure to maintain adequate flood control capability.

The U.S. Army Corps of Engineers is developing a scope of work and schedule for the necessary repairs.

Meanwhile, a schedule of planned releases through the flood control structure is being coordinated and will be distributed.

The generation schedules for Narrows Dam posted on the SWEPCO website will not accurately depict actual water releases during this period of no generation. Seasonal rains may necessitate additional unplanned releases through the flood control structure.

Further notices will be distributed once a repair schedule is determined. These repairs are essential to ensuring the uninterrupted and safe production of hydropower in the future.

The optimal lake level for the required repairs has not yet been determined. Every effort will be made to minimize disruptions to the use of Lake Greeson and downstream Little Missouri River by visitors, partners, and stakeholders.

The Vicksburg District encompasses a 68,000-square-mile area across portions of Mississippi, Arkansas, and Louisiana, that holds nine major river basins and incorporates approximately 460 miles of mainline Mississippi River levees.
