A bill to direct the Secretary of the Interior to carry out a feasibility study on a selective water withdrawal system at Glen Canyon Dam, and for other purposes.

# Summary of S 3743: Glen Canyon Dam Water Withdrawal Study **What the Bill Would Do** This bill would require the Secretary of the Interior to study whether a "selective water withdrawal system" could be installed at Glen Canyon Dam in Arizona. Such a system would allow water to be drawn from different depths of the reservoir, potentially improving water quality and environmental conditions downstream. The bill directs the government to investigate the technical feasibility, costs, and benefits of implementing this technology. **Who It Affects** The bill primarily affects water users in the Southwest, including states that rely on the Colorado River (Arizona, Nevada, California, and others), tribal nations, hydroelectric power generation, and environmental groups concerned about downstream ecosystems.

Glen Canyon Dam plays a major role in managing water distribution across the region and maintaining Lake Powell, so any changes could impact millions of people and various industries. **Current Status** S 3743 is currently in committee as of the 119th Congress and has not yet been voted on by the full Senate. The bill was introduced by Senator Mike Lee (R-UT), reflecting regional interest in exploring new management approaches for the dam.
