You are now in California and the U.S. category.

California has been blessed with the distinction of being home to some of the richest and the poorest income-earning Americans, according to a 2015 report by the Social Science Research Council. This stark division of wealth between the extravagantly rich and the destitute is displayed vividly in how the state’s residents consume water. On the one hand, some estate owners have been publicly shamed for watering their lawns during extreme drought with thousands of gallons per day – sometimes five or 10 times the average household rate.

Facing pressure from Gov. Jerry Brown, Southern California’s largest water agency could vote as soon as April on whether to take a majority stake in the twin-tunnels project Brown plans for the Sacramento-San Joaquin Delta. The fast-track timeline was disclosed Tuesday at a committee of the Metropolitan Water District of Southern California, which heard a report from staff members about the benefits, risks and financing possibilities of the agency agreeing to pay the majority of the costs in a twin tunnels system.

A pair of storms will swing into California this week, potentially unleashing the most significant precipitation to impact the state in over a month. As the state contends with a worsening drought, depleted snowpack and renewed fears for the water supply in the coming months, the unsettled pattern may slightly ease, but not fully wipe out, these concerns. Abnormally dry winter months have caused moderate to severe drought conditions to blossom in much of central and Southern California, according to the latest report from the U.S. Drought Monitor.

A little-studied, underground layer of rock may provide a vital reservoir for trees, especially in times of drought, report scientists funded by the National Science Foundation (NSF) and affiliated with The University of Texas (UT) at Austin and the University of California, Berkeley. The study, published today in the journal Proceedings of the National Academy of Sciences (PNAS), looked at the water stored inside the layer of weathered bedrock that lies under soils in mountain forest ecosystems.

Machines that prod clouds to make snow may sound like something out of an old science fiction movie. But worsening water scarcity, combined with new evidence that “cloud seeding” can work, is spurring states, counties, water districts and power companies across the thirsty West to use the strategy. Last month, a study funded by the National Science Foundation tracked for the first time how the technology works in nature. The evidence for cloud seeding has been scarce, but recent research has encouraged officials and companies desperate to increase the amount of water in rivers and reservoirs.
