San Diego County Mitigation Efforts Aid in California Drought Battle

As the drought deepens throughout California, San Diego County has postured itself to make it through dry spell conditions as a result of planning and mitigation efforts.

After experiencing a severe drought in the early 1990s, San Diego County officials went to work on diversifying its water supply. At the time, the region was hit with 50% supply reductions because it relied almost entirely on a single source. Since then, however, the San Diego County Water Authority has taken a varied approach. According to the authority, the region has added a new transfer of conserved agriculture water from Imperial Valley and completed the All-American and Coachella Canal lining projects to receive conserved water from the Colorado River.

“The Water Authority’s draft 2020 Urban Water Management Plan shows that regional investments in a ‘water portfolio approach’ to supply management and a sustained emphasis on water-use efficiency mean that San Diego County will continue to have sufficient water supplies through the 2045 planning horizon – so the region’s residents and economy remain safe even during multiple dry years,” the authority told 10News.

Running Out of Water and Time: How Unprepared is California for 2021’s Drought?

With most of the state gripped by extreme dryness, some conditions are better, some worse, than the last record-breaking drought. Over-pumping of wells hasn’t stopped. But urban residents haven’t lapsed back into water-wasting lifestyles. “We are in worse shape than we were before the last drought, and we are going to be in even worse shape after this one,” said Jay Lund, co-director of the Center for Watershed Sciences at University of California at Davis.

California Farmers Facing Drought Are Choosing Empty Fields

In some areas of California it’s so dry that farmers aren’t even bothering to plant crops this season. Growers north of San Francisco have begun pulling out of local farmers markets and produce-box programs. County Line Harvest, which farms more than 30 acres in Petaluma, California, doesn’t have enough water to grow all the peppers, lettuces and other produce that normally go into its subscription boxes, according to a video posted to its Instagram page.

East Bay Water Officials Have Eyes On The Future

East Bay Municipal Utility District officials have seen droughts come and go. But they seem to be coming more frequently this century.

Climate change is stoking devastating wildfire seasons year after year, drying the state out and just making it more flammable the following year. State water officials say that means less water in the Mokelumne River Watershed, the main source for EBMUD and its 1.4 million customers.

Last winter was the state’s driest since 1977, prompting the district to officially declare a stage one drought on April 27 and ask customers to cut ten percent of their water use. What can the East Bay expect moving forward?

New Research Finds Climate Models Mostly Get It Right

New climate research, which was done mostly in San Diego, finds that a study of land temperatures during the last ice age confirms some widely held thoughts about climate change.

Lead author Alan Seltzer, a paleoclimatologist at the Wood’s Hole Oceanographic Institute, studied ancient water as a way to gain insight into previously unrecorded planetary temperatures.

State Plans to Order Drought Restrictions, But it Doesn’t Have Good Water Data to Do It

As California descends deeper into drought, state regulators are planning to do something they’ve done few times in modern history: order thousands of people, farms, and even cities and towns that hold historic water rights to stop drawing water from the rivers, lakes and ponds they rely on.  The move is intended to make sure the dwindling flows in California’s waterways are reserved for those with the most senior water rights, as well as for fish and other wildlife.

Many of those with lesser rights would have to turn to storage, groundwater or another source, if they have it.  The problem, besides leaving several in a tough spot, is that the state doesn’t have an accurate tally of how much water is being pulled from its watersheds, nor who exactly is taking it.

Water Usage Down Sharply in San Diego, Shrinking City’s Reliance on Expensive Imported Supplies

San Diego’s vulnerability to water shortages and drought is shrinking significantly because residents and businesses are using less water and city officials are boosting the local supply.

A new city analysis shows local water use dropped sharply from 81.5 billion gallons in 2007 to about 57 billion gallons in 2020, even though the city’s population has grown about 1 percent per year over that time.

Dry Soils And Drought Mean Even Normal Snowpack Can’t Keep Up With Climate Change In The West

Brian Domonkos straps on a pair of cross-country skis and glides through the trees along Mosquito Creek west of Fairplay.

It’s May, but there’s still snow in Colorado’s mountains near the headwaters of the South Platte River.

Domonkos, the Colorado Snow Survey supervisor, gets to work measuring how much snowpack is left from the winter to runoff into streams, rivers and reservoirs this summer.

A Few Lessons for California’s New Drought

We asked some colleagues for lessons that might be useful in managing the California’s new drought. Here is a first sampling of thoughts.

Water Crisis “Couldn’t be Worse” on Oregon-California Border

The water crisis along the California-Oregon border went from dire to catastrophic this week as federal regulators shut off irrigation water to farmers from a critical reservoir and said they would not send extra water to dying salmon downstream or to a half-dozen wildlife refuges that harbor millions of migrating birds each year.

In what is shaping up to be the worst water crisis in generations, the U.S. Bureau of Reclamation said it will not release water this season into the main canal that feeds the bulk of the massive Klamath Reclamation Project, marking a first for the 114-year-old irrigation system.
