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.
The Biden administration released an environmental analysis Tuesday that outlined two ways that seven Western states and tribes reliant on the overtapped Colorado River could cut their use, but declined to publicly take a side on the best option.
One option would be more beneficial to California and some tribes along the river that have high-priority rights to the river’s water.
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.
Reclamation’s draft Supplemental Environmental Impact Statement (SEIS) analyzes two alternatives, plus a no-action alternative, to protect critical elevations at Lakes Mead and Powell, the two reservoirs California depends on for its river supplies. Both reservoirs have declined due to unprecedented low levels from more than two decades of drought.
The release of the draft SEIS, which would modify the set of operating guidelines that manage river operations through 2026, comes even as heavy snows this winter signal some relief on the river.
“While this winter’s storms delivered an incredible snowpack, the release of the draft SEIS highlights that we need to continue to work with all Basin states, the tribes and Mexico toward a consensus-based approach that provides real and lasting solutions for all water users,” said Dan Denham, deputy general manager for the San Diego County Water Authority.

The first of the two action alternatives in the draft SEIS acknowledges the priority system for water rights under existing agreements and laws. The San Diego region’s river supplies are largely protected from reductions because they are tied to California’s senior rights within the Lower Colorado River Basin as well as the Imperial Irrigation District’s (IID) high priority rights through the Water Authority’s conserved water transfer agreement with IID.
The second alternative calls for Reclamation to analyze the effects of reductions “distributed in the same percentage” for all water users in the Lower Basin states – California, Arizona and Nevada – despite there being no precedent or foundation for this approach under existing laws. It would mean across-the-board reductions for all water users in the region, including those with senior water rights.
Reclamation has stated it is expecting input from states, tribes and water agencies to fine-tune and adjust these alternatives. Discussions are ongoing between stakeholders.

“The Water Authority will continue to work in collaboration with our partners on the Colorado River Board of California to ensure California’s high priority water rights on the river are upheld through this SEIS process while we also work with all river stakeholders to develop long-term, durable solutions for the river,” Denham said.
The draft SEIS will be available for public comment for 45 calendar days and the final SEIS is anticipated to be available with a Record of Decision in Summer 2023, according to the Bureau of Reclamation. Comments on the draft SEIS are due May 30. This document will inform the August 2023 decisions that will affect 2024 operations for Glen Canyon and Hoover Dams.
The proposal to address immediate water supply challenges complements Reclamation’s ongoing process to develop new guidelines for Colorado River Operations when the current interim guidelines expire at the end of 2026.
The U.S. Department of Interior announced Tuesday that it could ― and possibly would ― impose cuts to Colorado River deliveries starting next year if necessary, ignoring historic water rights held by the powerful Imperial Irrigation District and other rural farming districts.
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.
Local, regional, state and federal officials celebrated the project‘s completion with a ribbon-cutting ceremony Tuesday at MiraCosta College. The officials highlighted the various funding sources for the new pipeline while also pointing out the various infrastructure projects online and under development to increase local water supply sources in San Diego County.
“Every drop of recycled water used on our landscapes replaces a drop of imported drinking water,” said OMWD Board President Christy Guerin. “With the ongoing challenges we’re facing on the Colorado River, expanding our recycled water distribution system to convert more customer irrigation systems to sustainable, local supplies is of paramount importance.”
Congressman Mike Levin attended the celebration along with representatives from Senator Catherine Blakespear’s office and Assemblymember Tasha Boerner Horvath’s, as did local agency partners San Diego County Water Authority, San Elijo Joint Powers Authority, and the City of Encinitas.
“Creating a water system that is not dependent on imported supplies is vital for the long-term sustainability of the region,” said Congressman Levin. “Every project that expands the use of recycled water lessens our dependance on imported supplies and improves our resiliency to future droughts. The collaborative approach taken by neighboring agencies to complete this project is an exemplary way to strengthen the region’s infrastructure.”

“The completion of this project represents a necessary effort by numerous agencies to lessen the region’s dependence on imported water,” said Assemblymember Tasha Boerner Horvath. “The climate crisis is creating unpredictable weather patterns and we must invest in projects that will improve the region’s long-term resiliency to drought.”
Senator Catherine Blakespear said recycled water projects are becoming a critical tool in the fight against drought. “This project is a great example of how water agencies can work together to lessen our dependance on imported water supplies and create a more sustainable water supply portfolio,” said Blakespear.
Water conservation is a way of life for all Californians, and San Diego residents have embraced water-efficiency. Over the past decade, residents and businesses across the county have adopted “WaterSmart” plants, irrigation technologies and habits that not only save money, but also create vibrant yards, reduce energy use, protect natural resources and reduce landscape maintenance.
The San Diego County Water Authority and its member agencies collaborate with organizations and other agencies to offer a variety of WaterSmart tools, including classes and rebates, along with a water-use calculator and other resources.

The new pipeline is an element of the larger North San Diego County Regional Recycled Water Project, a collaborative effort among nine North County agencies that coordinate across jurisdictional boundaries. The recycled water being delivered through the new pipeline is produced at San Elijo Joint Powers Authority’s water reclamation facility in Cardiff.
“This project further expands the reach of our local recycled water system and makes drought-proof water for irrigation available for Encinitas’ schools, churches, and greenbelts,” said Encinitas Mayor Tony Kranz, “and it’s a great example of local agencies working together to develop cost-effective solutions for our residents.”
Expanding the use of recycled water for irrigation, as a renewable and locally produced water source, is an important strategy to reduce overall dependence on imported potable water.
OMWD has successfully converted Westmont of Encinitas to recycled water for landscape irrigation. The assisted living facility is the first of many customers along the Manchester Avenue and South El Camino Real corridor to tap into the newly installed recycled water pipeline.
Customers connecting to the new 1.4 mile six-inch diameter pipeline will irrigate with recycled water, reducing the demand for imported drinking water by more than 27 million gallons per year, according to the OMWD.
Additional customers along the corridor are working to convert their irrigation systems to accommodate the new recycled water supply, which will ultimately reduce demand for imported potable water by more than 27 million gallons every year.
“Investing in drought-resilient supplies is a top priority and every new recycled water customer we connect to our distribution system decreases demand for imported water,” said OMWD Board Secretary Larry Watt. Photo: Olivenhain Municipal Water District
OMWD serves up to 15% of its overall demand from recycled water and continues to identify additional ways to make recycled water available to eligible customers. In addition to recycled water efforts, OMWD is working on an additional project to construct a brackish groundwater desalination plant to further diversify supplies and provide ratepayers with a local source of drinking water. These supply projects, combined with conservation efforts, will help to ensure that OMWD customers will have the water they need during future droughts.

The project was funded in part by a $600,000 Proposition 84, Round 4 grant and a $750,000 Proposition 1, Round 1 grant via the California Department of Water Resources Integrated Regional Water Management Program. The new recycled water pipeline is also part of a suite of projects receiving $23.9 million in funds from the US Bureau of Reclamation’s Title XVI Water Reclamation and Reuse Program.
The Olivenhain Municipal Water District is a public agency providing water, wastewater services, recycled water, hydroelectricity, and operation of Elfin Forest Recreational Reserve. Organized in 1959, OMWD currently serves approximately 87,000 customers over 48 square miles in northern San Diego County.

As winter approached, few anticipated what was about to hit California.
Mired in a serious drought, the state was suddenly battered by an onslaught of 31 atmospheric river storms in a matter of months. While the number alone isn’t exceptional, the location, intensity and duration of these storms had a transforming effect on California’s climate. Record snowfall. Deadly flooding. The end of many drought restrictions.
On Monday, California water officials slogged through deep snow 7,000 feet above sea level, west of Lake Tahoe, to affirm what everyone already knew: A series of Pacific storms has generated record-level amounts of precipitation, filling reservoirs, inundating low-lying towns and fields and threatening more disastrous flooding as the Sierra snowpack melts.
