California’s ‘Shade Balls’ Deemed Successful in Saving Water

One year later, the shade balls dumped in the Los Angeles Reservoir have proven to be successful in saving water, according to the L.A. Department of Water and Power. In August of last year, L.A. officials released an additional 20,000 balls into the Los Angeles Reservoir, bringing the total number of balls in use to 96 million. The 36-cent plastic balls were designed to block sunlight, preventing chemical reactions that can cause harmful algae blooms.

Think California’s Current Drought is Bad? Past Incarnations Have Lasted Hundreds of Years

California is now five years deep into one of its most severe droughts on record, and scientists are continually probing the different factors that affect the state’s climate, and how much those are related to the overall warming of the globe. Increasingly, this means looking back into the past for clues about how the region has changed over the last few thousand years and what influences might shape its future. In this connection, new research published Thursday in the journal Scientific Reports suggests the Pacific Ocean may play a bigger role than anyone thought — and an unexpected one.

Cal Fire: Dying Trees Are State’s Largest Natural Disaster

As the California drought persists, dying trees are slowly becoming the state’s largest natural disaster, Cal Fire said.

Group Studies New Way of Dealing With Dairy Wastewater

I drove out past Merced last year to see a dairy farmer testing a new idea. He irrigated 40 acres of feed corn with drip lines, which are much more common in orchards and vineyards than annual crops. The lines did more than conserve water. They delivered fertilizer, in the form of nitrogen-rich wastewater from one of the farm’s manure lagoons. Such precise application could reduce the risk of pollutants seeping into drinking-water aquifers – a concern with the widespread practice of flood irrigating with lagoon water.

Delta Island Purchase Gets Go Ahead by State Supreme Court

The California Supreme Court has ruled that a Southern California water supplier can go ahead with the purchase of five Delta Islands, regardless of the opposition and lawsuit against it. Metropolitan Water District (MWD) will go ahead with the $175 million sale of the Delta Islands as ruled by the Supreme Court. Since MWD initiated the sale, several injunctions have been placed against it stopping the purchase from going through. Several lawsuits have also been filed by San Joaquin and Contra Costa counties, Delta Island farmers and a series of environmental groups.

 

Global Warming Could Make The Drought Last For a Century, Says UCLA Study

Greenhouse gases trapped in the upper atmosphere are acting like natural climatic forces that made some ancient droughts last for 1,000 years, UCLA researchers say. Global warming created by these gases could be making a more arid climate, like what California has seen in its current five-year drought, “the new normal,” said UCLA geography professor Glen MacDonald, the study’s lead author.

Denham Introduces New Water Infrastructure Bill

Congressman Jeff Denham introduced the New WATER Act Thursday in hopes of authorizing a pilot project that would provide long-term, low-cost financing for water resources infrastructure in reclamation states.“The Central Valley desperately needs to build more infrastructure for water storage and delivery,” said Denham, who introduced the bill Thursday.

 

Gov. Brown Signs Water Conservation Measure

Assembly Bill 1928, by Assembly member Nora Campos (D-San Jose) was signed by Governor Brown this week. The bill resets deadlines for the California Energy Commission to establish water efficiency performance standards and labeling requirements for landscape irrigation equipment by Jan. 1, 2018. “AB 1928 will help California further reduce water waste by taking the next step in improving outdoor water conservation and allow consumers to make informed choices about water-efficient equipment” said Campos.

 

New State Water Plan May Force Tighter Conservation Restrictions

San Francisco faces potentially drastic cutbacks in its water supply, as state regulators proposed leaving more water in three Northern California rivers Thursday to protect wildlife in the Sacramento-San Joaquin River Delta estuary, the linchpin of California’s water supply. The draft rules by the State Water Resources Control Board would raise the amount of water into the Merced, Stanislaus and Tuolumne rivers to 30 to 50 percent of what would naturally flow in them. That means less water would be available for urban users and farmers in the northern San Joaquin Valley, compounding their need to conserve.

An Era of Limits: California Proposes Steering More Water to Fish, Less to Farms, Cities

In a move that foreshadows sweeping statewide reductions in the amount of river water available for human needs, California regulators on Thursday proposed a stark set of cutbacks to cities and farms that receive water from the San Joaquin River and its tributaries. To protect endangered fish at critical parts of their life cycle, regulators proposed leaving hundreds of thousands of additional acre-feet of water in the San Joaquin River system.
