Rocky Mountain Snow Pack Good for the Valley, Pandemic Not So Good

The water and electrical divisions of the Imperial Irrigation District presented positive and negative reports respectively to the IID Board at the Tuesday, Jan. 18, regular meeting.

IID Water Manager Tina Shields gave a hydrology report about the recent, “nice little snowpack” brought by the recent storm. She said the Bureau of Reclamation had been having operational discussions of moving waters to Lake Powell to keep its water levels from falling below the minimum level necessary for the lake’s Glen Canyon Dam turbines to generate hydroelectricity. The snowpack will keep the water level high enough for the turbines to intake water for producing electricity.

After Snowy December, California Suddenly Turns Dry, Magnifying Drought Concern

California is approximately halfway through what may be the most closely watched wet season in state history. A rainy October and snowy December brought some relief from the extensive, multiyear drought, but a vanishingly dry January portends continuing water challenges.

Parts of central California have seen a record lack of precipitation so far this month.

What happens in the weeks ahead will have huge implications for the summer dry season. Almost all of the precipitation that nourishes soil and fills reservoirs in the western United States falls from November through March.

The U.S. Can’t Control the Tijuana Sewage Faucet

The United States and Mexico disagree on the source of a weeks-long sewage spill at the border, but an investigation into the cause demonstrated what those working on the border already know — the South Bay International Wastewater Treatment Plant in San Diego is in desperate need of repair. 

As of Friday, U.S. officials at the International Boundary and Water Commission — a binational agency that works on border water treaties — believed the millions of gallons of raw sewage that escaped the border wastewater system earlier this month came from a crack in a big concrete pipe in Mexico called the International Collector, which carries sewage from Tijuana wastewater mains to the U.S. treatment plant. (That pipeline is old and by now has surpassed its useful life, according to a 2019 report by the North American Development Bank.)   

Reps. Levin, Peters Preview Improvement to Local Infrastructure From $1.2 Trillion Spending Bill

Two San Diego-area lawmakers previewed on Monday the local improvements that will come from the $1.2 trillion bipartisan infrastructure bill passed by Congress last year.

Rep. Scott Peters vowed to help San Diego secure significant funding from the $7.5 billion earmarked in the Infrastructure Investment and Jobs Act for a national network of chargers for clean electric vehicles.

“The success of this landmark bill depends on focused federal, state, and local coordination to use these funds and ultimately improve San Diegans’ quality of life,” said Peters at a press conference with city and county leaders in Liberty Station.

Sierra Snow Levels Still Above Average, More Storms Predicted First Week of February

The National Weather Service in Sacramento tweeted Sunday that, despite California having a mostly dry January, snow depth and snow water content “is looking good and still running above average for this time of year.”

Currently, the Northern Sierra is at about 113 percent of what is considered the normal amount of snow for this time of year. Central Sierra snow is at about 109 percent. Overall, the state has about 111 percent of its average snowpack right now, thanks to the record-breaking storms that came toward the end of 2021.

SWP Water Allocation Increased After December Storms

Last week the Department of Water Resources (DWR) announced it will be increasing allocations for the State Water Project. In a press release, DWR Director Karla Nemeth said that December storms have allowed the Department to convey and store water in the San Luis Reservoir. Those storms and additional water have enabled a modest increase in deliveries. The State Water Project (SWP) allocation has been increased to 15 percent of requested supplies for 2022.

Who Governs California’s Drinking Water Systems?

A key feature of California’s drinking water system is the large number of individual water systems. There are approximately 3,000 Community Water Systems (CWSs) in the state, meaning systems that serve a residential population year-round (the remaining 5,000 of the state’s 8,000 Public Water Systems are non-community systems serve places like schools, daycare, hospitals, campgrounds, or businesses that serve at least 25 people but have transient or non-residential populations).

Supreme Court to Review Which Wetlands Get Federal Water Protections

The Supreme Court will review the question of which wetlands get protections under the Clean Water Act, a case with implications for water pollution and business operations.

The court on Monday agreed to take up the question of what legal test should be used to determine whether certain wetlands are protected under the federal law.

At issue is the case of Michael and Chantell Sackett, who, in 2007, started to build a home on a vacant lot that they own. The Sacketts had obtained local permits for the construction, but the Environmental Protection Agency (EPA) determined at the time that the activity was a violation of the Clean Water Act because the lot contains wetlands that qualify for protections.

New Irrigation Technology Could Save Water for Arizona Farms

The Central Arizona Project, which delivers Colorado River water to more than 80% of Arizona’s growing population, is taking a three-pronged approach to the megadrought that has resulted in the first water cutbacks to Arizona farmers.

One of those approaches is N-Drip, which converts flood-irrigated fields into a drip system that uses gravity, with no external form of energy. Developed by an Israeli company, the system is being tested to grow sorghum in Australia, sugar cane in Thailand and now cotton and alfalfa in Arizona.

College Scholarships Offered for Water Industry Education

Multiple California water associations and water agencies in San Diego County are offering college scholarships to help candidates achieve their goals.

A large number of recent retirements combined with the need for a skilled workforce up to date on new technologies have resulted in a critical need to increase the talent pool of skilled individuals in the water and wastewater industry, including in San Diego County.

Scholarships are available for community colleges, four-year colleges and universities, and graduate-level programs.
