Celebrating 79 Years of Engineering at the San Diego County Water Authority

The San Diego County Water Authority is celebrating National Engineers Week by highlighting how the agency’s engineers are instrumental in keeping the water flowing to San Diegans. Since the Water Authority’s formation in 1944, engineers have played a pivotal role in the establishment and growth of the agency and its commitment to delivering safe, reliable water supplies to San Diego.

(Editor’s Note: Founded by the National Society of Professional Engineers, National Engineers Week (February 19–25, 2023) is dedicated to ensuring a diverse and well-educated future engineering workforce by increasing understanding of and interest in engineering and technology careers.)

California Debates What to Do With Water From Recent Storms

Weeks after powerful storms dumped 32 trillion gallons of rain and snow on California, state officials and environmental groups in the drought-ravaged state are grappling with what to do with all of that water.

State rules say when it rains and snows a lot in California, much of that water must stay in the rivers to act as a conveyer belt to carry tens of thousands of endangered baby salmon into the Pacific Ocean.

South Coast Water District’s Desalination Project Will Provide a Local, Reliable Water Supply

South Coast Water District plans to decrease its reliance on imported water by creating a local, reliable, drought-proof supply through the Doheny Ocean Desalination Project. The project would also provide emergency water should the delivery of imported water be disrupted by earthquakes or other natural disasters.

Hopes Rise for Cold, Wet Weather Toward End of February in Northern California

 Ever since the late December and January deluge, California has been pretty dry. 

Since the beginning of February, Sacramento Executive Airport has recorded 0.56″ of rain. The relatively dry weather since mid-January allowed the state to dry out and lowered flood risk, but another storm cycle heading into the dry season would be incredibly beneficial in terms of breaking out of drought.

California Water Board Urged to Declare Emergency at Mono Lake

California authorities face renewed pressure to preserve the valuable salty waters of the Mono Lake — as despite recent rainfall, a historic drought and demands from the Los Angeles area have depleted it.

In a workshop Wednesday, the state Water Resources Control Board discussed Mono Lake’s current conditions amid the impacts of severe drought and ongoing diversions.

Lake Powell Drops to a New Record Low as Feds Scramble to Prop It Up

Water levels in Lake Powell dropped to a new record low on Tuesday. The nation’s second-largest reservoir is under pressure from climate change and steady demand, and is now the lowest it’s been since it was first filled in the 1960s.

Water levels fell to 3,522.16 feet above sea level, just below the previous record set in April 2022. The reservoir is currently about 22% full, and is expected to keep declining until around May, when mountain snowmelt will rush into the streams that flow downstream to Powell.

The Colorado River’s Urgent Lesson for Energy Policy

The Colorado River, which allows the desert to sustain itself and powers millions of American homes, is currently engaged in the fight of its life. The rapidly sinking river—victim of a nearly 23-year-long megadrought—stretches 1,450 miles, snaking its way from Colorado through Arizona, Nevada, and California, and finally into Mexico, where it should theoretically dump out into the Sea of Cortez.

Reclamation Hopes for 100 Percent Water Allocation

With a much improved rainfall season and snowpack — at least for one year — the water allocation outlook for the area appears to be looking much better than in past years.

The federal Bureau of Reclamation has stated it’s requesting a 100 percent water allocation locally for Class 1 Friant contractors. In addition is stated it plans to request a 20 percent allocation for Class 2 contractors.

DWR, Reclamation Submit Request to Adjust Water Right Permit Conditions to Conserve Storage

Following the driest three-year period on record, California experienced one of the wettest three weeks in January. But now those extreme wet conditions have activated a water quality standard in the Delta that, coupled with the extended dry period since then, could result in a sharp reduction in the amount of water that can be retained or moved into storage for both the State Water Project and federal Central Valley Project.

The Department of Water Resources and the U.S. Bureau of Reclamation are working in real time to operate the state’s water system to maximize water supply while protecting species and the environment. However, California continues to experience unprecedented swings in weather impacting water management operations.

Saltwater Flow Battery Added to Solar-On-Canal Project

A California water irrigation district has launched Project Nexus, which is installing a 4 MW solar canopy on an irrigation canal in California.

ESS Inc., a saltwater energy storage system manufacturer, has announced the delivery of an Energy Warehouse system to the Turlock Irrigation District in central California. The energy storage company will deploy a few Energy Warehouse containers to pair with solar panels over irrigation canals.
