Water Restrictions Lifted for Millions in SoCal, but Region Still Urged to Conserve

Mandatory water restrictions are being lifted for nearly 7 million people across Southern California following winter storms that have boosted reservoirs and eased the severe shortage that emerged during the state’s driest three-year period on record.

Citing improvements in available supplies, the board of the Metropolitan Water District of Southern California has decided to end an emergency conservation mandate for agencies in Los Angeles, Ventura and San Bernardino counties that rely on water from the State Water Project.

4S Ranch Water Reclamation Facility Honored as California’s Plant of the Year

The Olivenhain Municipal Water District’s 4S Ranch Water Reclamation Facility was named 2022 Plant of the Year by the California Water Environment Association.

At its March 15 meeting, the Olivenhain Municipal Water District Board of Directors accepted the award as the CWEA San Diego section’s 2022 Plant of the Year. The Plant of the Year award acknowledges OMWD’s 4S Ranch WRF accomplishments in regulatory compliance, innovative practices, cost-effectiveness, and superior plant operations.

Scientists: Largest US Reservoirs Moving in Right Direction

Parts of California are under water, the Rocky Mountains are bracing for more snow, flood warnings are in place in Nevada, and water is being released from some Arizona reservoirs to make room for an expected bountiful spring runoff.

All the moisture has helped alleviate dry conditions in many parts of the western U.S. Even major reservoirs on the Colorado River are trending in the right direction.

Southern Sierra Has Biggest Snowpack Ever, Runoff Under Control for Now

The southern Sierra now has the largest snowpack in recorded history (as measured by snow water equivalent). Not just for March 15, but at any time.

As of Wednesday, the snowpack is 271% of normal and 260% of April 1 average.The Kings River Water Association confirms that is likely true for the upper Kings watershed as well.

Rainfall Breaks Records Across San Diego County, With Flooding Closing Roads

Record rainfall was reported across San Diego County on Wednesday, with numerous roads closed by flooding.

Oceanside Harbor received a record 4.21 inches, Vista 2.24 inches, Alpine 1.80 inches, Ramona 1.73 inches and Campo 1.17 inches.

Santa Barbara County Rainfall More Than 200% of Average to Date

The rain brought into Santa Barbara County by an atmospheric river Tuesday turned out to be less that forecast, but it still totaled between about 1.4 and 2 inches in most areas, although there were some notable exceptions.

Damage was also less as a result, with only minor localized mud flows, flooded streets and a couple of downed trees reported as of Wednesday morning.

Storms End Southern California Water Restrictions for 7M

California’s 11th atmospheric river left the storm-soaked state with a bang Wednesday, bringing flooded roadways, landslides and toppled trees to the southern part of the state as well as drought-busting rainfall that meant the end of water restrictions for nearly 7 million people.

Water Authority Seeks Public Input on 2024 Rate Increase and Two-Year Budget

The San Diego County Water Authority has asked for public input over the next two months as it drafts a new two-year budget and sets rates to cover the cost of water-reliability projects that keep San Diego immune from drought.

Agency staff has recommended a $1.85 billion budget for the two-year period beginning July 1, 2023, and ending June 30, 2025.

That represents a 5% increase, but the 2024 rate increase is tentatively set at 14%, though efforts are underway to lower that.

How Rising Temperatures Are Intensifying California’s Atmospheric Rivers

California is no stranger to big swings between wet and dry weather. The “atmospheric river” storms that have battered the state this winter are part of a system that has long interrupted periods of drought with huge bursts of rain — indeed, they provide somewhere between 30 and 50 percent of all precipitation on the West Coast.

The parade of storms that has struck California in recent months has dropped more than 30 trillion gallons of water on the state, refilling reservoirs that had sat empty for years and burying mountain towns in snow.

Opinion: Why Rain-On-Snow Floods From Atmospheric Rivers Could Get Much Worse

California’s latest atmospheric rivers are sending rainfall higher into the mountains and onto the state’s crucial snowpack. The rain alone is a problem for low-lying areas already dealing with destructive flooding, but the prospect of rain on the deep mountain snow has triggered widespread flood warnings.

When rain falls on snow, it creates complex flood risks that are hard to forecast. Those risks are also rising with climate change.
