The Department of the Army, through the USACE St. Louis District, is seeking businesses to design and install a debris barrier system for the gravity drain at Clarence Cannon National Wildlife Refuge in Annada, Missouri. The project involves creating a system that can be raised during gate operations to prevent woody debris, ranging from 1 to 6 inches in diameter, from entering the drain while allowing for water flow management. This initiative is crucial for maintaining the integrity of the gravity drain structure, which is vital for the refuge's water management.
