There are a number of factors to consider when declaring a state of emergency. After a dry water year, little to zero water allocations, Agriculture Secretary Tom Vilsack declaring drought conditions in counties up and down the state and even the entire republican delegation sending letters Governor Gavin Newsom, Congressman Jim Costa said declaring drought can be tricky.
At the Solvang City Council meeting last Monday, the council members approved a resolution to ask neighbors to voluntarily cut back on their water intake by 15%.
They also voted to impose mandatory restrictions and spend $400 thousand on supplemental water.
Solvang declared a stage one drought `condition as Santa Barbara County faces a moderate drought that is getting worse.
As drought deepens across the West, California’s decision to limit State Water Project (SWP) deliveries to 5% forced Metropolitan Water District of Southern California to increase pumping from the Colorado River near Lake Havasu. The good news: there’s water behind Hoover Dam for them to use. The bad news: As MWD draws on what they call “intentionally created surplus” under a previous agreement, Lake Mead will fall below the threshold for Tier 1 restrictions, leading to a curtailment of water deliveries to Arizona farmers.
California has entered another drought.
But depending on who you ask, the last one may have never really ended.
Some researchers believe the region is actually more than two decades into an emerging “megadrought” — a hydrological event that is on par with the worst dry spells of the past millennium. Except this time, they say, human-caused climate change is driving its severity — and will make it that much harder to climb back out of.
California is once again into a critically dry year with memories of the last drought all too fresh. Scientists warn that “boom or bust” water years are the new normal, and we all knew we’d be back here again. The question is, what have we learned and what have we done about it?
Borrego Springs, the small desert town at the entrance to California’s sprawling Anza-Borrego State Park, has won a judge’s approval for an agreement under which large farmers, resort owners and its own water district will slash water use by 74% by 2040. Officials say the cuts are needed to keep the town of 3,000 alive.
More than a dozen major landholders, including ranchers and developers who’ve long grown crops and created lush golf greens in the parched desert by pumping large amounts of water from a rapidly depleting aquifer, signed on to the settlement agreement. Together with the town, their share of water rights total more than 75% of an estimated 24,000 acre-feet of water pumped annually out of the desert floor. Within 19 years, that is required to plummet to about 5,700 acre-feet.
The man-made lakes that store water supplying millions of people in the U.S. West and Mexico are projected to shrink to historic lows in the coming months, dropping to levels that could trigger the federal government’s first-ever official shortage declaration and prompt cuts in Arizona and Nevada.
The U.S. Bureau of Reclamation released 24-month projections this week forecasting that less Colorado River water will cascade down from the Rocky Mountains through Lake Powell and Lake Mead and into the arid deserts of the U.S. Southwest and the Gulf of California. Water levels in the two lakes are expected to plummet low enough for the agency to declare an official shortage for the first time, threatening the supply of Colorado River water that growing cities and farms rely on.
The Colorado River’s biggest reservoirs are likely to drop to historically low levels later this year, prompting mandatory conservation by some of the river’s heaviest users.
The latest Bureau of Reclamation reservoir projections, which take into account river flows in a given year, show a likelihood that Lake Mead on the Arizona-Nevada stateline will dip below the critical threshold of 1,075 feet in elevation in May and remain below that level for the foreseeable future.
A first-ever official shortage declaration from the Department of the Interior is almost certain later this year. According to the terms of a 2007 agreement, a shortage is declared by the Interior Secretary after consulting with water users in the Lower Basin states of California, Arizona and Nevada. An August report is used to forecast when Lake Mead will be below 1,075 feet at the start of a calendar year.
Three potable water reuse or recycling projects under development in the San Diego region were highlighted this week during the San Diego Green Building Council’s inaugural “Sustainable Building Week San Diego.”
The Sustainable Building Week programs focused on sustainable practices and creating collaboration and networks among San Diego professionals involved with environmental stewardship and green building.
The City of San Diego’s Public Utilities Department has completed the 2020 Watershed Sanitary Survey, which evaluates any potential water quality issues at the source and will be used as a basis for future watershed management and planning efforts. A watershed is an area of land that drains water into a specific body of water. Everything that is on the land, whether a natural feature or a human activity, is part of the watershed. Issued every five years, the report identifies actual or potential causes of local source water contamination that might adversely affect the quality and treatability of water used by the City. The City’s tap water meets all state and federal drinking water health standards, which are the primary standards for treating and monitoring water.
