The California Department of Water Resources announced an increased water supply allocation for 2024.
The forecasted allocation has increased to 40%, up from 30% last month.
The increase would provide an additional 420,000 acre-feet of water, according to the department. That’s enough water to serve around 1.5 million households for a year.
After a dry start to winter, California’s rainy season is finally well under way. December downpours sent water racing through streets in coastal Ventura County and the city of Santa Barbara. Flash floods hit San Diego in late January, and back-to-back atmospheric river-fueled storms arrived earlier this month, causing wind damage in Northern California and hundreds of mudslides in Los Angeles.
In the past few decades, we have witnessed the pendulum swinging back and forth in California between managing drought, to questions about how we will handle too much water. While the weather might be fickle, one thing is certain, climate change will make extreme weather more common and will require residents to invest in their stormwater infrastructure.
As the rain year continues to look promising, rice farmers are happy to expect most if not all of their water allocations will be delivered.
This week the Department of Water Resources announced a 75% water allocation to the irrigation districts served by the State Water Project.
The devastating drought is continuing to ravage the Central Valley and is creating more of a water crisis for farmers.
Right along the edge of West Fresno County sits miles and miles of uprooted almond trees. Farmer Joe Del Bosque says he’s never seen it like this.
When you go to the grocery store and fill the cart with food for your family, you are part of a long process that begins with soil, water, sunlight and the labor of farmers and farm workers. Most likely, the farms that grow most of your food are in a neighboring rural area or within a day’s drive from your home. California grows 61 percent of U.S.-produced fruits, nuts and vegetables. Many of our winter fruits and vegetables come from the Imperial and Coachella valleys as well as from the San Joaquin, Salinas and Sacramento valleys the remainder of the year.
Droughts in the Western U.S. make headlines worldwide, posing particular challenges for people living and working in the affected regions. Here’s a close examination of the effects of drought on available water resources.
The Effects of California Drought Vary by Location
People regularly discuss California when talking about long-term drought, particularly because the state often experiences prolonged water shortages. Some experts believe that rather than going through brief non-drought periods, the state is actually enduring a so-called emerging megadrought and has been for the last two decades.
The American Public Works Association and American Society of Civil Engineers recently presented the San Diego County Water Authority with four awards for construction projects that exemplified outstanding skill, dedication and collaboration from staff in many departments. All of the projects were underway or completed during the COVID-19 pandemic, and project teams navigated shutdowns, adapted to health and safety restrictions, and overcame many other uncertainties – in addition to typical challenges encountered during construction projects.
With extensive coordination between the Water Authority’s Asset Management, Operations, Maintenance, Right of Way, Water Resources, Engineering and Public Affairs teams, the First Aqueduct rehabilitation project was completed in early 2021. Significant work had not been performed on the First Aqueduct since the completion of Pipeline 1 in 1947 and Pipeline 2 in 1954. The Operations and Maintenance Teams worked closely with multiple member agencies to ensure no impacts to water deliveries over the extended shutdowns required to reline both Pipelines. These extended shutdowns allowed the Asset Management team to inspect 27 miles of pipeline along the aqueduct using innovative technologies – the first time this had been done in nearly 75 years.
“Since the project included more than 35 work sites spread out over 15 miles, many in rural areas of the county, we collaborated closely between different departments and member agencies to ensure that water service was not disrupted,” said Emma Ward-McNally, Water Authority engineer.
This new facility replaced the existing Vallecitos 2/Vista Irrigation 1 facility that was built in 1954. The Water Authority’s Operations and Maintenance team worked closely with the Engineering team to develop a construction sequence to build the new facility while maintaining water service to member agencies.
“A meticulous level of detail in the design process allowed for the project to be completed with minimal changes during construction,” said Jim Zhou, Water Authority senior engineer.
The new flow control facility replaced the San Diego 12 flow control facility. The Water Authority’s Right of Way team worked closely with the City of San Diego to acquire property rights for the facility. During construction, electrical and rotating technicians from Operations and Maintenance provided support to ensure that the facility was constructed correctly and that electrical relay protection was coordinated when connecting to San Diego Gas & Electric.
“The new facility repurposed an existing building at the site, but it was forward-looking – the project included the installation of a second pipe train for a future inline hydroelectric turbine,” said Aaron Trimm, Water Authority senior engineer.
After nearby Pipeline 4 was repaired in late 2019, the Asset Management team inspected Pipeline 5 in early 2020, and found it needed repairs as well. Multiple Water Authority departments and teams collaborated to launch the emergency repairs on Pipeline 5, despite the uncertainty of the growing pandemic. The Engineering Contracts group executed five contracts and task authorizations for design, construction and inspection within a few weeks to make the project happen, and the work was completed in April 2020.
“The project was a true team effort that required collaboration from multiple departments to ensure that the emergency repair could be completed even as the region was shutting down due to the pandemic,” said Colin Kemper, Water Authority senior engineer.
The California Department of Water Resources has marked 2021 as the third-driest water year, a period marked from October to March, on record for the Golden State, potentially setting up another deadly wildfire season after last year’s record setting blazes.
