Storm More Than Doubles Totals For Rainfall Year

Butte County got a best soaking of the rainfall year from the storm that rolled through Monday and Tuesday, with another shot due to arrive Thursday. Wednesday might be the only nice day of the week, according to the National Weather Service, which is forecasting Thursday’s storm could linger until next week. The past storm brought more to the area than it had total so far this rainfall year, which began Oct. 1, roughly doubling the rainfall totals. Monday and Tuesday brought 2.24 inches of rain to Chico, 0.95 inch to Oroville, and about 5.4 inches to Paradise.

Reservoirs Provide Tap Water Yet Significantly Contribute To Climate Change

Hydropower dams are generally thought to be a clean source of electricity. By moving water through turbines, dams can generate large amounts of electricity almost continuously and without causing air pollution. It’s partly for these reasons that more than 3,700 hydroelectric dams are currently proposed or under construction worldwide. But a growing body of science reveals a dark side. It turns out the reservoirs formed by dams are a significant source of greenhouse gases – particularly methane, about 34 times more potent than carbon dioxide. In the last 10 years, dozens of studies have shed light on this problem.

 

OPINION: How To Revive A Dying Delta

Scientific reports published over the past several years have been unambiguous. The delta, the largest estuary on the West Coast, is on the brink of collapse. Starved of freshwater inflow due to dams and water diversions, the Sacramento-San Joaquin River Delta’s health has faced a precipitous decline over the past few decades. The recently released Bay Delta Water Quality Control Plan offers our last best hope to revive the estuary that defines our region.

BLOG: Delta Tunnel Alternative: Embracing Flooding For Water Supply

When California officials got serious about building two giant tunnels to divert freshwater out of the Sacramento-San Joaquin Delta, it didn’t take critics long to propose alternatives. One of the first was a grassroots scheme that, at first, seemed radical and counterintuitive: Let winter floods retake vast parts of the San Joaquin Valley – the very farmland that needs those Delta water diversions. The floods would recharge depleted groundwater that could then be used to irrigate the farms, preventing the need for Delta water exports.

Sites Reservoir Backers Prepare To Seek Bond Money

Backers of the proposed Sites Reservoir west of here believe they have plenty of momentum going into next year’s application period for Proposition 1 water bond funds. The number of agencies signed on to participate in the project has grown from 14 to 34, including from the San Francisco Bay area and San Joaquin Valley, said Jim Watson, general manager of the Sites Authority. And the Legislature recently passed Assembly Bill 2553, a bipartisan measure that will give flexibility in construction methods to help speed the project.

Late-Week Storm To Deliver Critical Rainfall To California

Rain will douse California late this week, with the potential for some rain to reach southern portions of the state. While the rain will be beneficial in terms of the drought, enough rain can fall to cause travel disruptions and localized flash flooding from Thursday to Friday. More than 40 percent of California is dealing with extreme to exceptional drought, according to the latest U.S. Drought Monitor released on Oct. 20. Prior to the late-week dousing, showers will affect portions of northern and Southern California into Tuesday before dry weather returns for a time.

Weak La Nina May Help Ease Drought

Federal climatologists predict that dry conditions will generally recede over the winter in Oregon, Idaho, Washington and parts of Northern California, providing an early and upbeat outlook on next year’s water supply. The Climate Prediction Center forecast a 70 percent chance of a weak La Nina, a cooling of the ocean around the equator. La Nina generally tilts the odds in favor of wetter and cooler winters in the northern U.S., according to the center. It’s not a sure bet, though. La Nina’s influence will vary by region. The odds it stays through the winter are 55 percent.

Avocado Shortage Affecting Restaurants, Grocery Stores Across Central Coast

Some bad news for avocado lovers — some local restaurants have taken the fruit off their menus due to a shortage. Several things play into this shortage, including California’s drought and an early harvest. Plus, according to local avocado farmers, growers in Mexico went on strike because they weren’t happy about the prices they were getting. “And that’s what you have now, is a created shortage by them because they did a shutdown,” said Alan Cavaletto, Morro Creek Ranch General Manager.

A Solution To California’s Drought?

New research may have found a solution to address California’s prolonged period of drought. A study conducted by researchers at Stanford University suggests that California’s aquifers, underground areas where water collects, may have up to three times the amount of useable groundwater as previously estimated. The research estimates that the previously untapped deep groundwater source could hold up to 2,700 billion tons of freshwater under the state’s Central Valley.  Historically, deep groundwater aquifers have been developed for gas and oil extraction, rather than used as a viable water source.
