Glen Canyon Dam Hydropower and Environmental Management

under operation with environmental management adjustments

The Glen Canyon Dam on Lake Powell produces hydroelectric power distributed to several states. Due to climate change and water overuse, the dam's ability to generate power is threatened. A Biden-era decision allows periodic water releases bypassing power generation to control invasive smallmouth bass threatening the native humpback chub fish. Utah Republicans and power providers oppose this decision, seeking to prioritize hydropower production. The dam has eight generators producing about 5,000 gigawatt-hours annually, serving multiple states. The Western Area Power Administration distributes this power. The dam's hydropower production has declined due to reduced water levels, impacting energy costs and infrastructure funding. Efforts to balance environmental protection and energy production continue, including experiments to flush out invasive fish without significantly reducing power generation.
