Colorado River

Falling water levels in reservoirs along the Colorado River have forced cuts to some water users in the state, but headlines saying Arizona farms are losing their water are a bit misleading. Arizona Edition’s Lou Gum speaks to Yuma attorney Wade Noble about Yuma's water rights. 

  

The threats to the Colorado River are many – climate change, overuse, invasive species, dozens of planned diversion projects, pollution – and that has motivated action up and down the river’s shores by a variety committed activists and regular people.

The water levels behind the Colorado River’s biggest dams are fast-approaching or already at record lows. The historic 21-year megadrought that is squeezing some Western states’ water supplies will also likely start showing up in energy bills, because those dams can’t produce as much electricity. 

Drier springs bring hotter summers in the withering Southwest

A question has bothered climatologist Park Williams during the decade he’s been probing drought in the Southwest. Like other climate scientists, he knew from research papers and worldwide storm patterns that a warming atmosphere is thirstier and sops up more moisture from oceans and the land.

The Cocopah are known as the river people for their historic and cultural connection to what is today called the Colorado River.

The Colorado intersects the Cocopah Reservation today at a couple of points, but it is harder to get to the waters than it used to be just a couple of generations ago.

A Colorado River Showdown Is Looming. Let The Posturing Begin

(Luke Runyon, KUNC)

 


A showdown is looming on the Colorado River. The river’s existing management guidelines are set to expire in 2026. The states that draw water from it are about to undertake a new round of negotiations over the river’s future, while it’s facing worsening dry conditions due in part to rising temperatures.

A recent report from the Center for Colorado River Studies at Utah State University takes a deep dive into the history of water flow on the Colorado River to help water users assess the future of this high use, drought plagued resource. Professor Jack Schmidt is the Center's Director. Today we take a quantitative look at the future of a river that was once called the Nile of America.

Gov. Says He'll Veto Unfair Drought Plan

PHOENIX -- Gov. Doug Ducey threatened Tuesday to veto any drought contingency plan that does not equitably divide up the pain of Arizona having less water in 2020 and eventually leads to lower water use in the state.

The vow, the governor's strongest statement to date on the issue, comes as the key players in crafting a plan appear to be circling around an agreement of who loses water when the state is forced to reduce the amount it can draw from Lake Mead and the Colorado River.

June 29th was the last day on the job for Yuma Crossing National Heritage Area Executive Director Charles Flynn.  Flynn was honored this week during the annual meeting of Visit Yuma for his impact on the community.  KAWC's Kim Johnson was there and has details.....

In his 19 years on the job Flynn is credited with being the catalyst for Yuma's reconnection with the Colorado River.  He says when he arrived in Yuma it was a river city with no river access, but he says he knew people here wanted that to change.....

In Yuma, Arizona, the Colorado River is not what it was.  For thousands of years, its raging water deposited rich soil in the delta, creating one of the most verdant agricultural areas in the world.  Today, the river flow is 1 percent of what it was a century ago, but agriculture continues to thrive even as the water needed to maintain it dwindles due to over-allocation and drought.

But the often muddy and fast flowing canals can be a “death trap” for those who venture too close.

In 2014, the U.S. and Mexico agreed to release more than one-hundred-thousand acre-feet of Colorado River water from the Morelos Dam near Yuma, Arizona to the Sea of Cortez in Mexico.

It was part of a historic agreement called the Minute 319 Pulse Flow and it may have had some environmentally unfriendly side-effects.

It had been more than two decades since Colorado River water flowed into the Sea of Cortez. The intent of the release was to help restore a parched ecosystem damaged by drought and high demand.
