A “normal winter” is forecast into spring, predicted the Bay Area’s weather wizard, Michael Pechner of Golden West Meteorology. On the heels of last year’s milestone rain and snow totals for much of Northern California and with residual high lake levels going into fall, a normal winter would fill most recreation lakes for summer camping, boating and fishing and provide good winter conditions for snow sports in April.
The 2019 movie “Dark Waters” alerted the public to health hazards posed by perfluoroalkyl and polyfluoroalkyl substances (PFAS, also know as PFOA and PFOS) that contaminated water and groundwater around manufacturer DuPont’s facility in Parksburg, West Virginia. The chemicals have been linked to deaths, cancer and more–and they are pervasive, found in 97% of Americans tested, PBS reports, citing a U.S. National Health and Nutrition Examination study in 2015.
In California’s never-ending water and fish wars, the striped bass doesn’t get nearly the publicity as its celebrity counterparts, the endangered Chinook salmon and Delta smelt. Yet the striped bass is at the heart of a protracted fight over California’s water supply, 140 years after the hard-fighting fish, beloved by anglers, was introduced here from the East Coast. Wealthy agricultural and Southern California urban water interests, tired of seeing their Central Valley water supplies reduced to protect native fish, have been quietly waging a war against the bass because they prey on hatchling salmon and adult smelt. They’ve repeatedly tried to introduce legislation or change regulations that would reduce the numbers of striped bass from the Sacramento-San Joaquin Delta.
January will continue to be dry in Southern California as the jet stream settles into a stable or zonal pattern, which means it flows more directly from west to east with little fluctuation. A wavy or undulating jet stream is the pattern that brings storms from the north Pacific into California. “When the winter jet stream calms down, Southern California stays dry,” says Bill Patzert, former climatologist at NASA’s Jet Propulsion Laboratory. When the jet stream is unstable, it meanders from north to south and back again. Cold air sinks farther south and warm air is carried into higher latitudes.
For decades, California’s coastal aquifers have been plagued by invading seawater, turning pristine wells into salty ruins. But the state’s coastal water agencies now plan to get more aggressive in holding back the invasion by injecting millions of gallons of treated sewage and other purified wastewater deep underground. The additional groundwater will both enhance potable water supplies and help prevent saltwater from seeping further into coastal California’s massive subterranean reservoirs. A decade ago, Orange County was the first in California to successfully employ this tactic — mocked by critics as a “toilet to tap” solution.
Rivers are vital. Like life-giving arteries, they deliver water for drinking and irrigation and fertile soil for vineyards and farms. They support watersheds teeming with life. But humans are hard on rivers. We crowd their banks, dump waste in them and take out water, fish and other resources. In the process, waterways often end up reduced to narrow, dirty channels, shadows of their former selves. When that happens, who speaks for the river? For our longest local river, that voice has often been the nonprofit Russian Riverkeeper.
The Trump administration has carried out a major rewrite of a key environmental rule, significantly tightening the definition of which bodies of water are subject to federal regulation under the Clean Water Act, and which are not. The rule, governing what the statute calls “waters of the United States,” (WOTUS) is important to the construction industry because it determines where contractors must get a federal permit before they build near wetlands or streams. Construction groups hailed the new rule, which top officials of the Environmental Protection Agency and Army Corps of Engineers signed on Jan. 23.
The San Diego County Department of Environmental Health issued a General Rain Advisory to avoid water contact at all coastal beaches and bays due to recent rainfall, Jan. 21. Swimmers, surfers, and other water users are warned that rain brings urban runoff, which can cause bacteria levels to rise significantly in ocean and bay waters, especially near storm drains, creeks, rivers and lagoon outlets. Urban runoff may contain large amounts of bacteria from a variety of sources such as animal waste, soil and decomposing vegetation. Bacteria Levels can remain elevated after a rainstorm depending upon the intensity of the storm, volume of runoff and ocean conditions.
The Trump administration on Thursday revealed an overhaul of the Clean Water Act that could remove federal protections for waterways around the country, including as many as two-thirds of those in California.
The arid West, where intermittent rainfall often flows through arroyos and washes, could be especially impacted by the rollback of federal jurisdiction, as the new “Navigable Waters Protection Rule” will remove federal oversight from ephemeral waterways created by rain or snow.
About 66% of California’s waterways are ephemeral or intermittent, according to the government’s own reports that were used in formulating earlier Clean Water Act rules. That number rises to 81% around the entire Southwest, including 94% of Arizona’s watercourses.
MERCED, Calif. (KFSN) — A new project at UC Merced is focusing on irrigation water.
The work could have a significant impact on the crops that are grown throughout the Central Valley.
“We’re trying to take two problems and come up with one solution out of the two of them. We have an excess of drainage water which has excess salt in it, and we need cooling of agricultural greenhouses,” says assistant professor James Palko.
