The San Diego County Water Authority supports a consensus-based approach for long-term solutions to water supply issues in the Colorado River Basin. The U.S. Bureau of Reclamation on April 11 released a draft environmental document that considers changes to near-term operations on the Colorado River, including potential reductions in water supplies for California and across the Lower Colorado River Basin.
A new recycled water pipeline in Encinitas is helping to reduce the region’s dependence on imported water supply. The Olivenhain Municipal Water District, or OMWD, constructed the Manchester Avenue Recycled Water Pipeline Project to expand the availability of recycled water within the City of Encinitas.
Imperial Irrigation District General Manager Henry Martinez issued the following statement in a press release on the draft Supplemental Environmental Impact Statement (SEIS) released today by the U.S. Bureau of Reclamation. The draft SEIS evaluates potential modifications to the 2007 Interim Shortage Guidelines that govern operation of the Colorado River’s major dams and reservoirs.
Southern California and the state as a whole could see dramatic reductions in allocations of Colorado River water under proposals released Tuesday by the federal government aimed at protecting a system that provides water to 40 million people in multiple states along with critical agricultural irrigation.
The river also provides hydroelectric power to millions of customers, generated by dams at Lake Mead and Lake Powell.
In what is expected to be one of the biggest snowmelt events in its history, California could see some 277 billion gallons of water flowing from the Sierra during the month of May alone.
Experts said Tuesday that the state’s biggest snow year since 1950 could result in a dangerous spring, as warming temperatures push high volumes of snowmelt downstream.
The Interior Department on Tuesday shared its proposal for expected cuts to Colorado River water allocations but acknowledged that the most extreme options — including a plan that would slash water deliveries to Arizona and Nevada — are unlikely to be included in a final decision this summer.
Instead, agency officials presented their emergency plan — which includes contrasting proposals that would either force California to forfeit a significant portion of its flows or concentrate the pain of cuts on Arizona and Nevada — as a set of “bookends” to motivate state officials to collaborate.
“I would not think about either of these three alternatives as something we’re asking people to choose, but rather, they’re models and alternatives and ways of defining the problem,” said Deputy Interior Secretary Tommy Beaudreau, referring to an update of the 2007 Colorado River Interim Guidelines.
This winter, storm after storm after storm dumped rain and snow on California, and now, as the spring poppies bloom, the state is lush. Hillsides once prickly with dry vegetation have softened. Ski resorts, once thawed out and closed by late spring, are buried under record snow and planning to stay open into July. Satellite photos show a state transformed from brown to green, streaked from top to bottom with bright-emerald patches.
A new water pipeline project recently finished construction in Encinitas. On Tuesday local and congressional leaders held a ribbon cutting to mark the opening of the pipeline.
The Manchester Avenue Recycled Water Pipeline Project involved the construction of approximately 1.4 miles of six-inch diameter recycled water pipeline. According to a press release, customers connecting to this new pipeline will now irrigate with recycled water, reducing the demand for imported drinking water by more than 27 million gallons per year.
The federal government on Tuesday laid out two options for preventing the Colorado River’s depleted reservoirs from falling to critically low levels, saying it could either impose cuts across the Southwest by following the water-rights priority system or by using an across-the-board percentage.
The Biden administration today proposed alternatives for cutting Colorado River water allocations for Southwest states, including one that would substantially reduce the amount of water delivered to Southern California.
One of the three options would retain California’s historic, century-old senior water rights, while another would override them and split the cuts in water deliveries evenly between California, Nevada and Arizona. The even-split option would be a big blow to Imperial Valley farmers while benefiting the other states.
