The U.S. Army Corps of Engineers (USACE) St. Louis District is seeking businesses to provide a debris barrier system for the gravity drain at the Clarence Cannon National Wildlife Refuge in Annada, Missouri. This project involves designing and installing a system that can be raised when the existing overshot gate is in operation and must be removable during water overtopping events. The barrier is intended to prevent woody debris, ranging from 1 to 6 inches in diameter, from entering the drain, which has a concrete structure with a 16-foot wide and 18-foot tall opening. The gravity drain can hold approximately 4 feet
USACE St. Louis District is seeking businesses that can provide a debris barrier system at Clarence Cannon National Wildlife Refuge (CCNWR) gravity drain in Annada, Missouri. The gravity drain is along the southern exterior berm of the refuge along Bryant?s Creek. The gravity drain is a concrete structure with a 16 ft wide and 18 ft tall opening. The structure allows water to flow in and out of the refuge by operating an overshot gate. A bridge deck lays over the gravity drain to allow vehicular access along the berm. The bridge was designed to resist AASHTO HL-93 tandem and lane loads.The project consists of designing and installing a debris barrier system to the existing gravity drain structure that can be raised when operating the gate. The barrier must be removed during the event of water overtopping. The barrier must prevent woody debris from entering the gravity drain. The woody debris ranges from 1 in. to 6 in. in diameter. A maximum of two workers is desirable to operate and maintain the system. There are no power sources onsite and no permanent power sources are anticipated. The gravity drain holds approximately 4 feet of water when the gate is closed.The proposed design must follow USACE guidance and standards.The following figure shows the overshot gate at the gravity drain. The photo was taken from the refuge side during construction.
