There’s a chance water levels in the two largest man-made reservoirs in the United States could dip to critically low levels by 2025, jeopardizing the steady flow of Colorado River water that more than 40 million people rely on in ...

With another deadline missed Monday, the head of the Bureau of Reclamation is now looking for the governors in the states in the Colorado River basin to tell her what they think she should do to keep water levels from dropping even lower.

The Imperial Irrigation District wants $200 million for the Salton Sea, a massive, briny lake in the desert southeast of Los Angeles created when the Colorado River breached a dike in 1905 and flooded a dry lake bed.

After months of drought plan negotiations and as the deadline for Arizona to produce an internal agreement on water reductions nears, the state’s water interests have nothing to show for their efforts yet.

I applaud Governor Ducey’s and former Governor Babbitt’s public statements of support for Arizona’s adoption of the drought contingency plans (DCP), expressed last week. Arizona’s water future depends on careful conservation, management, and collaboration to ensure that all of our communities are able to plan well into the future. This leadership is a valuable and essential part of how we get to a more sustainable future for the Colorado River basin.

Tension over the drought-stressed Colorado River escalated into a public feud when four U.S. states accused Arizona's largest water provider of manipulating supply and demand, potentially threatening millions of people in the United States and Mexico who rely on the river.

Republicans say they're not satisfied with a U.S. Environmental Protection Agency claim that a 3-million-gallon toxic spill from an inactive gold mine was likely "inevitable," even though there had been prior warnings that such a spill could occur.

Citing the release of millions of gallons of toxic wastewater into a southwestern Colorado river earlier this month, a coalition of conservation groups, two Arizona Native American tribes and two county governments petitioned federal agencies Tuesday to tighten mining regulation on public lands.

Authorities say rivers tainted by last week's massive spill from an abandoned Colorado gold mine are starting to recover, but for the Environmental Protection Agency the political fallout from the disaster could linger.

Arizona officials continue to monitor a massive spill of toxic sludge that is heading toward the Colorado River, but most were hopeful Tuesday that it will have little impact by time it reaches the state.
