Vicksburg, Miss……The U. S. Army Corps of Engineers Vicksburg District’s Grenada Lake has completed its periodic inspection of the Granada Lake Dam. The outlet works flood gates are scheduled to be re-opened on October 17, 2015.
Dewatering of the gate began on September 26, 2015. The gate closures and dewatering of the outlet works was done in preparation for the periodic inspection performed on October 8, 2015. During this dewatering period, the conduit, wing walls, and stilling basin floor of the outlet works were thoroughly inspected and cleaned. This work allows general routine maintenance such as the repair of spalled concrete along the walls and floor and replacement of degraded wing wall monolith joint materials. The dewatering also allowed for the treatment of the outlet works relief wells to flush iron deposits from the well screens.
Periodic inspections are routine dam inspections performed every five years by multidisciplinary engineering teams to ensure operational integrity, structural stability, and dam safety, as required by Corps regulations.
The Grenada Lake project is an 87,000-acre, multiple use project that is managed for flood control, public recreation, conservation of fish and wildlife, and the proper stewardship of public lands. As stewards of public lands, the Corps of Engineers is dedicated to providing a safe, quality recreational experience for all visitors. Grenada Lake, located near the city of Grenada, is one of four Mississippi Corps lakes within the Vicksburg District boundaries.
