The federal government would study whether a special system could be installed at Glen Canyon Dam to allow water managers to withdraw water from different depths of the reservoir, which could help protect fish populations and improve water quality downstream. This feasibility study would examine the technical and financial aspects of such a system before deciding whether to actually build it. The study would affect water management decisions for the Colorado River and communities that depend on the dam for water and electricity.
