The Colorado River has been dammed, diverted, and slowed by reservoirs, strangling the life out of a once-thriving ecosystem. But in the U.S. and Mexico, efforts are underway to revive sections of the river and restore vital riparian habitat for native plants, fish, and wildlife. Last in a series.
The strategy of turning to groundwater pumping will test the limits of Arizona’s regulatory system for its desert aquifers, which targets some areas for pumping restrictions and leaves others with looser rules or no regulation at all. In Pinal County, which falls under these groundwater rules, the return to a total reliance on wells reflects a major turning point and raises the possibility that this part of Arizona could again sink into a pattern of falling groundwater levels — just as it did decades ago, before the arrival of Colorado River water.
Gov. Stephen Roe Lewis of the Gila River Indian Community said in a statement Thursday that a decision by House Speaker Rusty Bowers to move forward with a contentious water bill threatens the community’s plan to support the drought agreement. The Gila River Indian Community’s involvement is key because it’s entitled to about a fourth of the Colorado River water that passes through the Central Arizona Project’s canal.
Ominous predictions about the desert lake’s ecological collapse are beginning to occur. You can see this sea up close during our Lower Colorado River Tour, Feb. 27-March 1, when we will visit the fragile ecosystem and hear from several stakeholders working to address challenges facing the sea.
Arizona and California aren’t done finishing a plan that would establish how states in the Colorado River Basin will ensure water for millions of people in the Southwest, said the head of the agency running the negotiations. … One challenge comes from the Imperial Irrigation District, a water utility that serves the Imperial Valley in southeastern California. It hasn’t signed California’s plan because it wants $200 million to restore the vanishing Salton Sea, the state’s largest lake.
A year after Colorado River imports were diverted to urban areas from farms draining into the lake, dire predictions about what would occur are coming to pass. A long-predicted, enormous ecological transition is occurring this winter.
For generations, residents of the Southern California border town of Calexico watched with trepidation as their river turned into a cesspool, contaminated by the booming human and industrial development on the other side of the border in Mexico. As Washington debates spending billions to shore up barriers along the 2,000-mile southwest border, many residents in California’s Imperial Valley feel at least some of that money could be spent to address the region’s public health threats.
A notice published recently in the Federal Register is not sitting well with Imperial Irrigation District. That notice, submitted by the Department of Interior through the Bureau of Reclamation and published on Feb. 1, calls recommendations from the governors of the seven Colorado River Basin state for protective actions the Department of Interior should take in the absence of a completed drought contingency plan.
A major deadline just passed without unanimous agreement among Western states over the future of the Colorado River, so the federal government is one step closer to stepping in on the dwindling river that provides water for 1-in-8 Americans. The path forward has become murkier for the drought-stricken region now in its 19th year of low water levels after a January 31 deadline failed to garner signed agreements from Arizona and California.
Did the goalposts just move on us? … Media reports suggest that Reclamation is lumping Arizona with California, which clearly did not meet the deadline, in its reasoning for taking an action that we had all hoped to avoid. It’s easy to feel betrayed by that, to conclude that Arizona was asked to move mountains and then when we did, we were told it still wasn’t good enough.
Imperial Irrigation District staff was accused of trying to sell the IID’s invaluable assets short when they formally presented the broad terms of a water storage proposal at Tuesday’s IID Board of Directors meeting.
“The Imperial Irrigation District Board of Directors was briefed Tuesday about discussions between representatives of the United States and Mexico regarding a potential turnout from the All-American Canal to Mexico.”
“The transfer of water from the Imperial Irrigation District to San Diego and the Coachella Valley has netted the IID nearly $85 million over a 10-year period, and is expected to net the district more than $2.7 billion from 2009 through 2047, according to IID projections.”
“The Imperial Irrigation District Board of Directors approved a new fallowing program Tuesday that compensates landowners and tenants for water that is not used when agricultural land is taken out of production.”
“The Imperial Irrigation District Board of Directors took a small step forward on Tuesday to make the IID’s water delivery process more efficient. It unanimously approved five work authorizations for the design and engineering of canal interties or pumped connections.”
