California, Nevada and Arizona’s historic pact to cut their use of the Colorado River’s overtapped supplies should be enough to keep the basin’s massive reservoirs from hitting dangerously low levels — for now, a federal analysis reported today.
A proposed deal for California, Arizona and Nevada to take less water from the over-tapped Colorado River depends heavily on $1.2 billion in federal funds, which will pay farmers and others who agree to give up some of their supply over the next three years.
The immediate question before the seven states that use rapidly vanishing Colorado River water is not how to renegotiate the century-old agreement and accompanying laws that divvy up the supply.
California and other states will have to grapple with that problem soon enough, and it won’t be easy.
Life in the southwestern U.S. as we know it exists thanks to the water of the Colorado River, which flows for approximately 1,450 miles from the Rockies to the Gulf of California.
The river gets its water from the Colorado River drainage basin, which spreads some 246,000 square miles.
Exposed to the beating sun and hot dry air, more than 10% of the water carried by the Colorado River evaporates, leaks or spills as the 1,450-mile (2,334-kilometer) powerhouse of the West flows through the region’s dams, reservoirs and open-air canals.
For decades, key stewards of the river have ignored the massive water loss, instead allocating Arizona, California, Nevada and Mexico their share of the river without subtracting what’s evaporated.
The seven Colorado River basin states have until mid-August to come up with a plan to drastically cut their water use. Federal officials say the cuts are necessary to keep the river’s giant reservoirs from declining to levels where water cannot be released through their dams and hydropower production ceases. If state leaders fail to devise a plan, they could face a federal crackdown.
But while federal intervention is a key feature of Colorado River governance and management, to cajole stubborn water users into negotiating — it’s rarely tested.
Imperial County District 2 Supervisor Luis Plancarte called for a water shortage summit for all of the water providers in Imperial County to see where they stand with plans to reduce water consumption in light of extreme drought conditions in the state.
An emergency regulation was passed on May 24 by the state Water Resources Control Board, which required urban and commercial water suppliers to implement the second stage of their respective water shortage plans.
