## Summary

**A feasibility study to prevent downstream invasive species while protecting Glen Canyon Dam's hydropower output.** This bill would direct the Secretary of the Interior, acting through the Commissioner of Reclamation, to carry out a comprehensive feasibility study that analyzes engineering alternatives and hydrology to stop invasive species from moving downstream while evaluating impacts on hydroelectric performance. - Colorado River Basin states and contractors: The Colorado River Basin States and Colorado River Storage Project power contractors must be consulted, giving them a formal role in shaping the alternatives studied and in identifying available funding sources. - Power customers and ratepayers: The study must analyze effects on hydropower production and rates in consultation with the Western Area Power Administration, so chosen solutions could change generation patterns or costs. - Environmental and Grand Canyon protection: Studied options may include a thermal curtain or selective water withdrawal to reduce entrainment of invasive species and manage cold-water releases, consistent with the 2016 long-term experimental and management plan and the Grand Canyon Protection Act. - Process, timing, and funding: The Secretary would have 18 months to finish the feasibility study and must identify funding sources within 90 days. Funding would come from appropriated federal funds that are nonreimbursable and the authority provided by the section would expire five years after enactment.
