An invasive mussel that has taken up residence in Lake Powell on the Colorado River is threatening Utah’s push to develop a $1.8 billion pipeline to deliver water to fast-growing areas. The Army Corps of Engineers has asked the state to provide a plan on how it will prevent the pipeline from transporting quagga mussels from the lake on the Arizona-Utah border, The Salt Lake Tribune reported Friday. The 140-mile (225-kilometer) pipeline aims to transport water to Washington and Kane counties in southern Utah. The line is planned to end at Sand Hollow Reservoir near St. George.

The Department of Water Resources (DWR) announced Thursday it will increase the 2019 State Water Project allocation to 75 percent from 70 percent. According to DWR officials, this will be the final allocation for the calendar year. The initial allocation in November 2018 was 10 percent. “This winter’s robust storms resulted in above average snowpack and reservoir levels bringing California a much-improved water year from last year,” said DWR Director Karla Nemeth in a press release. “The full reservoirs will provide a healthy buffer for if we return to drier conditions next year.” According to the DWR’s website, a full reservoir provides optimal recreation opportunities and serves as a vital “water bank account” to help California cope with future drought conditions.
A federal judge has struck down Trump administration decisions that cleared the way for Cadiz Inc. to build a water pipeline across public land in the California desert. The ruling is a blow to the company’s decades-long effort to pump groundwater from beneath its desert property 200 miles east of Los Angeles and sell it to urban Southern California. Cadiz wants to use an existing railroad right of way across federal land to pipe supplies from its proposed well field to the Colorado River Aqueduct. In 2015, during the Obama administration, the U.S. Bureau of Land Management said Cadiz couldn’t use the right of way and would therefore have to obtain federal permission to run the proposed pipeline across surrounding federal land.
On a sunny afternoon in mid-April, Professor Eric Sanford crouched in a tide pool off Bodega Bay and turned over algae-covered rocks in search of a chocolate porcelain crab, a dime-size crustacean with blue speckles. The creature has been spotted in small numbers around Bodega Bay for decades. But five years ago a severe marine heat wave, dubbed “the blob,” caused a sharp increase in its numbers north of the Golden Gate, says Sanford, a marine ecologist who researches climate change and coastal ecosystems at UC Davis’ Bodega Marine Lab. “I look at how organisms adapt to climate change,” says Sanford, who regularly publishes articles in scientific journals on how life between the Northern California tides is changing.
A California Senate committee has voted in favor of a bill requiring that water providers notify their customers if they detect a class of chemicals called PFAS in drinking water. The Environmental Quality Committee passed AB 756 on Wednesday, 6-0. The bill now heads to the Appropriations Committee. If it passes there, the full Senate will vote on it. PFAS, which stands for per- and polyfluoroalkyl substances, are waterproof, grease-repellent, and heat-resistant chemicals that are fairly ubiquitous, found in popcorn bags, firefighting foams, nonstick pans, makeup, and even food like ground beef. Scientists estimate there are 4,700 PFAS, some of which have been linked to cancer, infertility, developmental disorders, increased cholesterol and weakened immunity.

This is the final allocation for the calendar year. The initial allocation in November 2018 was 10 percent. The 2019 allocation of 75 percent amounts to 3,145,105 acre-feet of water. “This winter’s robust storms resulted in above average snowpack and reservoir levels bringing California a much-improved water year from last year,” said DWR Director Karla Nemeth. “The full reservoirs will provide a healthy buffer for if we return to drier conditions next year.”
