UNCOVERED: Glen canyon dam - The Untold Story

In 1996, USGS released an 8-day Glen Canyon flood at 1,275 cubic metres per second to track sediment; 120 cross sections measured how the flood changed the Colorado River channel

Engineers conducted artificial flood releases from the Glen Canyon Dam to help revive eroded sandbars, simulating natural river dynamics affected by the dam's presence. Early findings were promising, showing increased sandbar growth, but the benefits diminished over time due to continued sediment blockage. Further flood events and enhanced monitoring strategies…

In 2024, managers deliberately cooled the Colorado River to protect the Grand Canyon from invasive smallmouth bass. 2 years later, no bass recruitment had been detected, but the effort cost $19.1 million in replacement power

Managers at Glen Canyon Dam used an unusual strategy to protect native Colorado River fish from invasive smallmouth bass: they deliberately cooled downstream water during periods when the fish could reproduce. The “Cool Mix” operation combined colder water from lower river outlets with water passing through power-generating penstocks, keeping temperatures…
