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.

Opinion: California’s Wildfire Warning and the Action We Need to Take

When weather patterns and conditions develop that fuel extreme fire behavior, the National Weather Service issues what it calls a “Red Flag Warning.” In response, firefighters rapidly shift resources, beef up staffing and alert nearby communities. It’s an all-hands-on-deck moment to prepare for the worst – one we’ve become increasingly familiar with, even in winter months.

People Haven’t Just Made the Planet Hotter. We’ve Changed the Way It Rains.

You probably noticed a lot of weird weather in 2021.

From record-breaking deluges and tropical storms to drought-stricken landscapes that erupted in wildfire, the nation seemed to lurch from one weather-related disaster to the next.

You’re forgiven if you dismiss these events as unrelated, albeit unfortunate, phenomena. But they actually share a common bond – they’re all part of a new climate reality where supersized rainfalls and lengthening droughts have become the norm.

Busting Water Limits Won’t Cost You in Marin County: Penalties Canceled as Rain Fills Reservoirs

After recent reservoir-boosting rainfall, Marin County’s largest water district decided Tuesday to repeal recently established financial penalties for excessive water use.

In September, the Marin Municipal Water District board adopted an ordinance that established financial penalties for exceeding certain water use limits it set in April as drought conditions worsened across the Bay Area and California.

In the September ordinance, the district set penalties for going over “tier 1” water usage, which, for single family households, is 65 gallons of water per person, per day. Penalties would range from $5 to $15, depending on how much customers went over that limit.

UN Report: the World’s Farms Stretched to ‘a Breaking Point’

Almost 10% of the 8 billion people on earth are already undernourished with 3 billion lacking healthy diets, and the land and water resources farmers rely on stressed to “a breaking point.” And by 2050 there will be 2 billion more mouths to feed, warns a new report from the United Nations Food and Agriculture Organization (FAO).

For now, farmers have been able to boost agricultural productivity by irrigating more land and applying heavier doses of fertilizer and pesticides. But the report says these practices are not sustainable: They have eroded and degraded soil while polluting and depleting water supplies and shrinking the world’s forests.

Water Board Tables Delta Drought Regulation

The State Water Resources Control Board on Wednesday withdrew an emergency drought regulation for the Sacramento–San Joaquin Delta.

Despite a dry January, board staff said the regulation, known as a temporary urgency change petition (TUCP), would not improve conditions if implemented as planned in February. They found no potential benefits to Shasta and Trinity reservoirs, which have the greatest need for water.
