Omaha District engineers conducted the first-ever 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.
This video shows how the team conducted the test and what it means for the continued safety and effectiveness of the Garrison Project.
