Sunday marked the hottest day of the year, so far. Many people made their way to Folsom Lake to enjoy the weather to find lake levels low as the state faces the threat of a drought. After two dry years in a row with little rain and snow, drought is a concern. Last week, Gov. Gavin Newsom said he has executive orders drafted, if needed.
California is nearing the end of the rainy season. Most of California’s rainfall tends to be between November to April. And so far this year has fallen below average. According to the National Oceanic and Atmospheric Administration, most of the Central Coast is around 50% of the rainfall we’d normally expect. The highest rain total is near Cachuma Dam at 60%. While the lowest is near Santa Barbara Airport at 46%. San Luis Obispo is in the middle at 54%.
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.
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?
Incomplete local record-keeping may stymie EPA efforts to locate the nation’s lead pipes to meet President Joe Biden’s goal of replacing them and improving drinking water quality, authorities say. A better way to reduce lead contamination in the nation’s drinking water, a former Environmental Protection Agency water chief says, is by enforcing an existing rule requiring utilities to replace some of their lead pipes every year.
The Biden administration’s infrastructure plan, released March 31, calls for replacing all lead drinking water pipes throughout the U.S. to avoid lead contamination drinking water similar to the crisis in Flint, Mich. As many as 10 million U.S. homes have lead service lines, the EPA said.
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.
Hundreds of farmers who rely on a massive irrigation project that spans the Oregon-California border learned Wednesday they will get a tiny fraction of the water they need amid the worst drought in decades, as federal regulators attempt to balance the needs of agriculture against federally threatened and endangered fish species that are central to the heritage of several tribes.
