This bill tells two federal agencies to make a plan, together, to study and deal with how a 2024 decision about managing Glen Canyon Dam affects the Upper Colorado River Basin Fund. That fund pays for everyday dam and power system needs, like operations, maintenance, and replacing critical parts. The plan must also look at how the decision changes hydropower from the dam, including any extra costs to buy replacement power and keep the grid reliable, and it must identify effects on threatened and endangered species. The agencies are directed to start this work as soon as the law takes effect . Background: the 2024 update focuses on fighting invasive smallmouth bass below the dam and using new science to time high-flow releases to protect the endangered humpback chub .

Key points:

• Who is affected: Communities and customers who rely on Glen Canyon Dam hydropower; programs supported by the Basin Fund; and protected fish species in the Colorado River .
• What changes: Agencies must sign a memorandum of understanding and create a plan to handle impacts on the fund, power production, power costs, grid reliability, and listed species .
• When: Work begins as soon as the law is enacted; no fixed deadline is stated .
