Spillway flow test conducted for Garrison Dam Safety Modification Project
Matt Stobbe, U.S. Army Corps of Engineers, Omaha District dam safety engineer, enters the Garrison Dam spillway a spillway following a functional flow test. 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.
