Congress Passes Colorado River Drought Plan With Unanimous Approval From Arizona Lawmakers

A bill that would authorize the federal government to enact a drought plan for Colorado River basin states in times of shortage has passed Congress and is on its way to the White House for the president’s signature. Rep. Raúl Grijalva, D-Ariz., and Sen. Martha McSally, R-Ariz., fast-tracked the measure, clearing a final hurdle for the drought plan, a product of years of long and complicated negotiations that crossed state and party lines. When enacted, the plan will spread the effects of expected cutbacks on the river and protect the levels of Lake Mead and Lake Powell, the river’s two largest reservoirs. Its aim is to protect water users from deep losses and keep the reservoirs and river healthy.

Western Bird Species Are Struggling In Face Of Rapidly Changing Climate

New research finds that climate change is putting stress on wetlands in the West’s Great Basin and that is putting pressure on bird populations navigating the Pacific Flyway. Changing water conditions linked to climate change are impacting the wetland habitats that waterbirds rely on. The basin includes most of Nevada and parts of Utah, Arizona, Oregon and the eastern edge of California. Warmer temperatures and less rain are affecting wetland habitats. “Eleven of those 14 birds that we looked at there were significant correlations between changes in climate and a decrease in population,” said Susan Haig, U.S. Geological Survey researcher emeritus.

Water Board Orders Water Prohibition For Cannabis Grows Through October

On March 29, the State Water Resources Control Board announced that cannabis cultivators with water rights are not allowed to divert surface water for cannabis cultivation activities at any time from April 1 through October 31 of this year unless the water diverted is from storage. The Board’s action is what is known as a “forbearance order” that is a central provision in state marijuana legalization policy. It’s really just common sense because it prohibits using water from surface sources, such as streams, creeks, and rivers during California’s dry season.

Reservoirs Release More Water In Anticipation Of Snowpack

Local reservoir managers are proactively releasing water at higher rates than usual in anticipation of increased inflows from heavy winter rains and snowstorms. The Central Sierra five station index has recorded 43 inches of rain since Oct. 1, the beginning of the water year – 129 percent of normal levels for April 1. The snowpack for the San Joaquin hydrologic region, which encompasses the northern portion of the San Joaquin Valley bordered by the Sierra Nevada on the east and coastal mountains of the Diablo Range on the west, is at 165 percent of its average with about 48 inches in snow water equivalent for this time of year, based on California Department of Water Resources data.

Oroville Residents Submit Petition To ‘Hold DWR Accountable’ To Federal Agency

A petition to “hold the DWR accountable” was hand-delivered this week by Butte County Supervisor Bill Connelly to the Federal Energy Regulatory Commission in Washington, D.C. The Feather River Recovery Alliance is the name of the nonprofit run by local volunteers who organized the petition. It evolved from the local advocacy group Oroville Strong which was affiliated with the Oroville Chamber of Commerce. Specifically, the Feather River Recovery Alliance is asking FERC to not reissue a license to the state Department of Water Resources to operate the Oroville Dam until terms of the agreement are renegotiated, including a new recreation plan. The group says it received 6,469 local signatures on the petition.

What Climate Models Get Wrong About Future Water Availability

One of the most challenging questions about climate change is how Earth’s warming atmosphere will affect water availability across the globe. Climate models present a range of possible scenarios—some more extreme than others—which can make it difficult for cities, states, and countries to plan ahead. Now, however, in a new study, Padrón et al. suggest a way to reduce uncertainty using precipitation patterns from the past. A rule of thumb for global warming’s impact on Earth’s water availability that was sometimes proposed in the past was that dry regions will get drier and wet regions will get wetter, also known as the DDWW hypothesis. But mounting evidence suggests the reality is more complicated.

Zapping Lead Pipes With Electricity Could Make Them Safer For Drinking Water

The toxic effects of lead—developmental delays, organ damage, even death—are well-known. But millions of Americans still rely on lead pipes to deliver drinking water. In an attempt to make them safer, researchers at the University of California, Berkeley, are working on a new technology that uses electrical current to rapidly build a protective layer on the insides of the pipes. In early tests they reduced the amount of the toxic metal entering water, but other scientists are skeptical of the method’s potential as a long-term solution.

California’s Emergency Alert System Has Been A Disaster. A Statewide Fix Is Planned

In Mendocino County, emergency staffers waited for a supervisor to show up before they warned residents of a growing fire siege in 2017. In Santa Barbara County, officials hesitated to issue blanket evacuation orders before mudslides ripped through Montecito in 2018 because they worried they might trigger a panic. And in Butte County in November, whole neighborhoods in Paradise were never told to evacuate as the Camp fire swept toward town. In each case, local emergency preparedness agencies failed to adequately warn communities that death was approaching. Experts say the failures point to an approach to emergency management — administered by individual counties — that has proved outdated in an era of massive, fast-moving wildfires and other extreme weather events.

River Levels Rise As More Water Released From Keswick And Oroville Dams

Water levels will rise on the Sacramento and Feather Rivers as federal and state authorities release more water from Keswick and Oroville Dams. Thursday morning by 10 a.m., the Bureau of Reclamation will increase releases below Keswick Dam from 20,000 cubic feet per second to 30,000 cfs. Sacramento River levels are expected to increase downstream of Keswick Dam. The increased releases are necessary to meet flood space regulatory requirements within Shasta Reservoir.

A California Tax To Clean Up Toxic Drinking Water Has Lawmakers Jumpy

The ghost of Josh Newman haunts the state Capitol, sending shivers through certain politicians’ spines at the mere mention of the scary word “tax.” The former lawmaker’s fate will make it difficult for the Legislature — even with supermajority Democratic control — to pass one of Gavin Newsom’s top priorities: a so-called water tax. The governor says the tiny tax is needed to raise enough money to clean up toxic drinking water throughout California, particularly in low-income farmworker communities of the San Joaquin Valley.
