Spillway flow test conducted for Garrison Dam Safety Modification Project
Staff from the U.S. Army Corps of Engineers, Omaha District, Garrison Dam Project provide support during a functional flow test of the Garrison Dam spillway. The test measured water depth and velocity to calculate total spillway flow, providing valuable data to help ensure the spillway’s long-term performance and reliability. The operation also tested the spillway’s tainter gates to confirm they are ready to perform their critical flood-control role during future high-water events.
