Drought and water issues push Lake Powell back into headlines as water levels drop, threatening supplies and power. Reservoir’s role? Utah/Arizona, Colorado River basin staple.
San Diego County's seawater desalination plant has operated at about one-third capacity since opening, prompting the water authority to explore interstate sales of Colorado River water rights as drought reduces flow into basin reservoirs and heightens scarcity across the West.
State regulators are inspecting dams after high waters, while federal action pushes more safety reforms; Lake Mead and Powell's levels are affecting power supply and flood readiness, with Michigan dams also facing scrutiny amid spring floods.
The Lewis & Clark Regional Water System and related projects are expanding water capacity along the Missouri River. The base system now delivers 44 million gallons daily to 20 communities, with two expansions under way and a separate pipeline project to support growth in the Black Hills region. Together, the initiatives could cost tens of billions and serve hundreds of thousands more residents over the next 40–50 years.
