Narrows Dam/Lake Greeson to Increases Current Releases

Vicksburg, Miss. – Due to recent heavy rains, the U.S. Army Corps of Engineers (USACE) Vicksburg District has increased current releases through the structure at Narrows Dam/Lake Greeson in Arkansas. The release will be increased to 2,200 cubic feet per second (cfs), which is equivalent to all three units generating at full load. 

Safety remains our top priority so please be aware of high water and currents. This release will affect the ability for some visitors to bank and wade fish downstream of Narrows Dam due to water level and increased flow.

Approximately one year ago, during maintenance activities on the trash racks at Narrows Dam at Lake Greeson, USACE 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 halted hydropower generation until repairs are completed. These repairs are essential to ensuring the uninterrupted and safe production of hydropower in the future. Work is tentatively scheduled to begin at the end of January 2025 and should take approximately seven months to complete.

This cessation has not impacted the ability to carry out flood risk management or other missions of the Narrows Dam/Lake Greeson Project. Water releases like these are executed through the structure to maintain adequate flood control capability. A significant drawdown of Lake Greeson is not anticipated to perform the repairs. 

All efforts will be made to minimize the disruption of the use of Lake Greeson and the Little Missouri River downstream for our visitors, partners, and stakeholders.

The USACE Vicksburg District is engineering solutions to the nation’s toughest challenges. 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. The Vicksburg District is engaged in hundreds of projects and employs approximately 1,100 personnel.
