Water Shortages Ahead? Sierra Nevada Snow Pack On Track To Shrink 79 Percent, New Study Finds

Every year, like a giant frozen reservoir, snow that falls across the Sierra Nevada mountain range slowly melts in spring and summer months, providing roughly one-third of the water supply for California’s cities and farms, from the Bay Area to Los Angeles. But at the current rate at which the climate is warming, the amount of runoff from Sierra snow into California’s largest reservoirs is heading for a dramatic decline — a 54 percent drop in the next 20 to 40 years and 79 percent in the next 60 to 80 years, according to a new study from scientists at Lawrence Berkeley National Laboratory.

OPINION: Gov. Brown Working To Save His Tunnels

In the world of water politics, where change occurs at a glacial pace, the past few weeks have seen enormous swings in how our state’s most precious resource is managed and delivered. The discussions behind these changes are not easily known and even less easy to understand what they ultimately will mean for cities, farms and, yes, fish in California as climate change accelerates. What is apparent however is that Gov. Jerry Brown is working hard to put his delta tunnels project on the glide path to the finish line before he leaves office in January.

OPINION: Sites Proponents Have Years Of Advocacy Ahead Of Them To Get the 500,000 acre-foot lake finally under construction

Sites Reservoir proponents are happy with what’s happened this year … they’ve collected commitments for some serious coinage – state and federal. They can stay grounded, however, by the fact that they’ve got several billion dollars still to go. There’s a lot of work ahead. The off-stream reservoir adds a sizable storage capacity to Northern California, with none of the environmental and fewer political traps of an on-stream dam.

Interior Secretary Ryan Zinke, Under A Cloud Of Scandal, Is ForcedOut

Interior Secretary Ryan Zinke, who endeared himself to President Trump but was caught up in scandals and infuriated environmental activists, will be departing his post by the end of the year in the latest shake-up of the president’s Cabinet. “Secretary of the Interior @RyanZinke will be leaving the Administration at the end of the year after having served for a period of almost two years,” Trump wrote on Twitter on Saturday morning. “Ryan has accomplished much during his tenure and I want to thank him for his service to our Nation.”

California Cedes Water To Feds In Delta Deal With Trump

Southern Californians could lose billions of gallons of water a year to Central Valley farmers under a deal Gov. Jerry Brown’s administration has struck with water officials working for President Donald Trump. There’s no guarantee the agreement with Trump will accomplish what Brown’s team is seeking: a lasting compromise on environmental regulations that could stave off significant water shortfalls for farms and cities across California. A powerful state agency, the State Water Resources Control Board, hasn’t yet signed off on Brown’s compromise environmental proposal. Environmental groups have called the governor’s idea woefully insufficient to save ailing fish populations.

Top Federal Water Official Gives States Jan. 31 Deadline To Pass Colorado River Drought Deal

Water leaders throughout the West now have a hard deadline to finish deals that would keep the Colorado River’s biggest reservoirs from dropping to deadpool levels – the point at which water no longer can be released. The nation’s top water official is giving leaders of the seven states that rely on the river until Jan. 31 to finalize a Drought Contingency Plan. The combination of multistate agreements would change how reservoirs are operated and force earlier water cutbacks within the river’s lower basin states of Arizona, California and Nevada as reservoirs drop.

A Larger Issue Looms Over Short-Term Colorado River Plan: Climate Change

With the water level in Lake Mead hovering near a point that would trigger a first-ever official shortage on the Colorado River, representatives of California, Arizona and Nevada are trying to wrap up a plan to prevent the water situation from spiraling into a major crisis. The plan is formally called the Lower Basin Drought Contingency Plan. But at an annual Colorado River conference this week, many water managers stressed that it’s merely a stopgap plan to get the region through the next several years until 2026.

UC Merced Researchers Assess Western Forests’ Ability To Survive Next Drought

By Lorena Anderson, UC Merced – UC Merced researchers have evidence that California’s forests are especially vulnerable to multi-year droughts because their health depends on water stored several feet below ground. “Each year our forests, grasslands and shrublands depend on water stored underground to survive the dry summers, but during multi-year dry periods there is not enough precipitation in the wet winter season to replenish that supply,” said Joseph Rungee, UC Merced graduate student and lead author on a new paper published in the journal Hydrological Processes.

Federal Officials Say Sewage Spill Stopped At U.S-Mexico Border Friday Morning

While a ruptured pipe in Mexico continues to spill sewage into the Tijuana River, federal officials said that as of Friday morning the effluent was being captured at the border and diverted to a wastewater treatment facility. Over the last few days, efforts to remove sediment and debris from pumps in the Tijuana River helped restart a diversion system that effectively ended the cross-border impacts at 7 a.m., which reportedly started Monday night from a broken pipe that leaked millions of gallons and shuttered South Bay beaches.

Tijuana Sewage Nightmare A Grim ‘Groundhog Day’ For San Diego County

Broken sewage infrastructure in Tijuana early this week sent roughly 7 million gallons a day of sewage into the Tijuana River, leading to beach closures along the south San Diego coast. The cause was a ruptured collector pipe in a part of the sewage system that has already received millions of dollars in upgrades in recent years, according to the International Boundary and Water Commission (IBWC), a joint U.S.-Mexico agency that oversees binational water issues.
