California Town Wonders if Restored Floodplain Prevented Disaster

When devastating floods swept California last month, the community of Grayson – a town of 1,300 people tucked between almond orchards and dairy farms where the San Joaquin and Tuolumne rivers converge – survived without major damage.

In the minds of some townspeople and experts, that was thanks partly to the 2,100 acres (850 hectares) of former farmland just across the San Joaquin that have been largely restored to a natural floodplain.

Wet Winter Won’t Fix Colorado River Woes

Snowpack has been running well above average this winter across the Colorado River watershed. It’s a rare bright spot after 23 years of grinding megadrought brought the driest conditions in 1,200 years to the basin that supplies 40 million people in Arizona, California, Colorado, Nevada, New Mexico, Utah, Wyoming, and Mexico.

Should the generous rains and mountain snows continue into spring, they could help head off a deeper water crisis, including perhaps an unprecedented loss of hydropower generation from severely depleted Lake Powell and Lake Mead.

California Finds Itself Isolated, Alone in Battle Over Colorado River Water Cuts

After a key deadline passed this week without an agreement on how to address the Colorado River’s crisis, California is now sharply at odds with six other states over how to take less water from the shrinking river.

Now that California has rejected a plan offered by the rest of the region, the state has entered a political tug-of-war with high stakes. So why has the state that uses the most Colorado River water decided to go it alone?

Recent Rains Are ‘Nowhere Near’ What California Might See in the Future, Climate Expert Says

The atmospheric rivers that pummeled California are a far cry from what a series of extreme storms could potentially bring, climate scientist Daniel Swain said at a legislative hearing on Wednesday that explored the impacts of the recent storm sequence.

“We’re nowhere near the kinds of events that we think are possible in a warming climate,” said Swain, a researcher at UCLA and The Nature Conservancy.

Despite an ‘Incredible’ Snowpack, Drought Not Over in California

California may celebrate having double the expected snowpack after a string of atmospheric river storms, but state water experts warn that more needs to come to offset years of record-breaking drought.

At the season’s second monthly snowpack survey conducted Wednesday at Phillips Station — at the intersection of Highway 50 and Sierra-at-Tahoe Road — the California Department of Water Resources measured current snow depths and water content.

California Has Huge Snowpack, but Dry Trend Raises Worries

The mountain snowpack that supplies a significant amount of California’s water got an incredible boost from recent powerful storms and is outpacing the state’s wettest season on record, state water officials said Wednesday.

But its too soon to know if the winter will be a drought-buster, they said.

Monthly Reservoir Report for February 2

The New Year’s Atmospheric River storms of 2023 have abated and catchments across the State are draining as exemplified by continuing baseflows through their hydrograph recession limbs.  River flows are still elevated, but releases have been incrementally curtailed and stage levels continue to drop.

Despite early positive signs, however, the reality of what this storm (or series of storms) brought in terms of drought relief is made eminently clear by reviewing various data sources.

California Water Agencies Submit Colorado River Modeling Framework to Bureau of Reclamation

California water agencies that rely on the Colorado River today proposed a modeling framework for the U.S. Bureau of Reclamation to evaluate as it considers actions to help stabilize reservoir elevations and protect critical infrastructure to ensure the Colorado River system can continue to support 40 million people, nearly 6 million acres of agriculture, and Tribes across seven states and portions of Mexico.

California Fires Back at Other Western States With Its Own Colorado River Plan

Dueling plans for how to save the fast-drying Colorado River have been submitted by California and six other states to federal authorities, who have made clear they may impose draconian cuts if consensus is not reached regionally on deep reductions. That agreement could be hard to come by.

California swung hard at six other Western states late Tuesday, submitting its own proposal for more than 3 million acre feet in reductions — both from current and future agreements — if necessary from the river’s dwindling reservoirs, Lake Powell and Lake Mead.

California Releases Its Own Plan for Colorado River Cuts

California released a plan Tuesday detailing how Western states reliant on the Colorado River should save more water. It came a day after the six other states in the river basin made a competing proposal.

In a letter to the U.S. Bureau of Reclamation, California described how states could conserve between 1 million and nearly 2 million acre feet of water through new cuts based on the elevation of Lake Mead, a key reservoir.
