Democratic Sen. Dianne Feinstein shaped California’s environment like no one else.
Since her first election to the Senate in 1992, the onetime San Francisco mayor made herself the Golden State’s go-to legislator. With key committee assignments and a pragmatic bent, the veteran lawmaker put herself into the room where the deals got done.
Against the backdrop of a severe drought linked with global warming, conservation advocates and Native Americans in California are calling for a temporary emergency stop to all surface water diversions from Mono Lake, contending that continuing to drain the watershed, along with the long-term drought, threaten critical ecosystems, as well as the Kootzaduka’a tribe’s cultural connection with the lake.
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.
The Water Authority’s first general manager, J. L. Burkholder, who oversaw the completion of Pipeline 1, which gave San Diego access to the Colorado River in 1947, also held the title of chief engineer. At the Water Authority, National Engineers Week is a time to remember its roots while also appreciating the team leading it into the future.
Water Authority Assistant General Manager Tish Berge, who is a registered professional chemical engineer, explained the importance of having a strong presence of engineers in organizations like the Water Authority.
“Engineering at its core is problem solving,” Berge said. “That type of thinking is applicable at all levels within an organization. At this stage in my career, the most rewarding aspect of my job is leading talented individuals and preparing the next generation.”
The Water Authority has 23 staff members that hold professional engineering or engineering-in-training licenses.

Emma Ward-McNally, engineer and construction manager at the Water Authority, said her love for science and curiosity of the world around her drew her into the field of engineering. She said her passion for problem solving keeps her going.
“I love my job because no two projects are ever the same and they all offer unique challenges and opportunities,” Ward-McNally said.
At the Water Authority, problem solving can look a little different than other retail water agencies, said Principal Asset Management Specialist Eric Rubalcava, who is a professional engineer.
Large diameter pipelines and structures allow for Rubalcava and his team to physically go inside the infrastructure for inspections. A typical inspection over the course of 10 days will cover 12 miles of pipeline. Rubalcava and his crew look for visible cracking of the pipeline liner, exposed or corroded metal, coating failures, spalled concrete, pulled joints; anything that provides evidence that our infrastructure is in a degraded state.
For Rubalcava, the job is rewarding because of his direct involvement in keeping the water system reliable by determining infrastructure needs.
“This work is physically demanding but I get to do something that most people don’t get to experience, including many of my Water Authority colleagues,” Rubalcava said.

Senior Engineering Technician Karla Sanchez spends her time out in the field above ground. One of her main roles is maintaining a presence at construction sites where she ensures that projects are meeting contract specifications.
“One of the favorite parts of my job is being out in the field monitoring construction and working with various talented individuals in the water industry,” Sanchez said.

When engineers aren’t out in the field, Senior Water Resources Specialist Anjuli Corcovelos said a typical day on the job includes data analysis, communication, and solving problems.
All this comes together when presented with projects like the Moosa Canyon Pipeline Repair and Replacement Planning Study. Corcovelos and her team had to determine which of the eight possible solutions would be best. The project involved coordination with several other departments as part of a massive team effort. It’s the type of project Corcovelos finds the most satisfying.
“Those challenges, those stressful days or nights trying to really figure out that solution, come together sometimes with other teammates to make that happen,” said Corcovelos. “But ultimately when you achieve that goal, and you identify what that solution is and be able to see those effects come to light, it really truly is very rewarding.”
Leading up to National Engineers Week, engineers across multiple departments at the Water Authority have been looking ahead together at what the future holds for engineering projects which will positively impact San Diego’s water supply.
Sami Sweis, professional engineer (PE) in Water Resources, is working with Corcovelos along with other departments and water agencies on his current favorite project: The 2023 Water Facilities Master Plan Study. The master plan goes all the way out to 2045 by evaluating existing and planning for new regional water facilities. The overall goal is to keep the water supply reliable and diverse while also maintaining or increasing operational resiliency and reliability.
“It’s really enjoyable because of the collaboration we have with our other departments and member agencies, and knowing that in the future we’re going to have some projects that are going to be beneficial to San Diego as a region,” Sweis said.
(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.)
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.
Because of these extreme weather swings, DWR and Reclamation are taking proactive measures to manage the state’s water supply to store and capture more water in preparation for a return to hot, dry weather in the next two months.
Both agencies submitted a Temporary Urgency Change Petition (TUCP) to the State Water Resources Control Board requesting approval to modify compliance with Delta water quality conditions specified in their water right permits, while proposing measures to avoid impacts on Delta smelt.
DWR and Reclamation typically would seek this kind of change during extremely dry conditions. But the swing to extremely wet conditions after extremely dry conditions has created challenges, and the projects are acting to enable additional opportunities for water storage north and south of the Delta while maintaining protections for species.
The request for the TUCP follows protective actions taken by DWR and Reclamation under state and federal endangered species permits in late December and early January, including the “first flush” action to reduce pumping and allow storm runoff to flow through the system for the benefit of native fish species. Recent monitoring information shows the actions worked as intended, with key fish species moving downstream of the Delta and away from the direct influence of the SWP and CVP pumps.
The water quality and water right permits that dictate SWP and CVP operations require certain water quality conditions to be met at specific compliance points in the Delta to provide for favorable conditions for endangered fish species. In consultation with the Department of Fish and Wildlife, DWR and Reclamation are requesting that the State Water Resources Control Board temporarily move the compliance point in the projects’ water rights permits from Port Chicago six miles east to Chipps Island. The alternative compliance point is anticipated to ensure water quality sufficient to protect beneficial uses.
If approved by the State Water Board, these actions would allow DWR and Reclamation to move and retain more stormwater and runoff in the state’s reservoirs in preparation for continued dry periods. A total of approximately 300,000 acre-feet would be saved for later use by the State Water Project alone.
While the January storms provided much-needed rain and snowfall, they did not end drought conditions for much of the state and California remains in a drought emergency. Regions that rely on the Colorado River system face increasingly severe water shortage conditions, and groundwater basins that serve communities in the Central Valley will not recover quickly from back-to-back years of drought and chronic overdraft.
DWR will continue to work with federal and state partners to be proactive and respond in real time to balance multiple water supply needs.
California is under new orders as of Monday to aggressively work to protect all water supplies from weather extremes brought on by climate change.
Governor Gavin Newsom signed an executive order to expand statewide storm runoff capture capacity, noting how years of prolonged drought finally paused after three weeks of atmospheric river storms slammed the Golden State at the beginning of the year.
Researchers at UC San Diego have launched a year-long project aimed at better understanding the region’s clouds and, by extension, global warming.
A bevy of equipment provided by the U.S. Department of Energy was recently deployed on Mount Soledad and at the university’s Ellen Browning Scripps Memorial Pier.
San Diego regional member water agencies and California water associations will offer multiple college scholarship opportunities in 2023 to help candidates secure their education as water and wastewater professionals.
For decades, Californians have depended on the reliable appearance of spring and summer snowmelt to provide nearly a third of the state’s supply of water. But as the state gets drier, and as wildfires climb to ever-higher elevations, that precious snow is melting faster and earlier than in years past — even in the middle of winter.
California and other southwestern states have been in the grip of a megadrought for the past two decades.
Scientists say that, despite recent storms, these drought-stricken states won’t be relieved from the hot and dry weather for a long time, and not without large amounts of rain.
Upper Colorado River Basin states have a new $125 million pot to rent and dry agricultural land and keep more water in the drought-plagued waterway, in a major expansion of a previous conservation pilot announced by the Biden administration’s Bureau of Reclamation.
