Upper Colorado River States Add Muscle as Decisions Loom on the Shrinking River’s Future

The states of the Lower Colorado River Basin have traditionally played an oversized role in tapping the lifeline that supplies 40 million people in the West. California, Nevada and Arizona were quicker to build major canals and dams and negotiated a landmark deal that requires the Upper Basin to send predictable flows through the Grand Canyon, even during dry years. But with the federal government threatening unprecedented water cuts amid decades of drought and declining reservoirs, the Upper Basin states of Wyoming, Utah, Colorado and New Mexico are muscling up to protect their shares of an overallocated river whose average flows have already dropped 20% over the last century.

Opinion: Climate Change is Here. It’s Time Californians Stopped Clinging to the Past

Life moves pretty fast. If you don’t stop and look around once in a while, you could miss it.

So says Matthew Broderick in “Ferris Bueller’s Day Off,” and he might as well be talking about California these days. As the planet continues to heat up, the state’s landscapes, watersheds and weather are shifting so fast it can be difficult to keep track.

Striking Before-and-After Satellite Photos Show the Great California Snowmelt Underway

As California’s wet winter has given way to warmer spring weather, the state’s record snowpack has begun to melt.

Though the accumulated snow still measures 249% of normal as of April 18, new satellite photos show that the white blankets enveloping mountains across the state have started to recede.

California’s Strategy Fails as Feds Pressure States to Conserve Colorado River Water

The Department of Interior has indicated that if states don’t cooperate on dividing Colorado River water, more cuts may be on the way.

The agency indicated that California could also face cutbacks, which means that the state’s wait-and-see strategy may have fallen short.

California has senior water rights to the Colorado River, and so far, that has worked in its favor.

How IoT-powered Soil Sensors Helped a California Golf Resort Save Millions of Gallons of Water Per Month

Although much of California no longer suffers from drought conditions thanks to the recent record rainfall, the Golden State isn’t quite yet out of the woods when it comes to a scarcity of water.

And that means sustainable water management must continue to be top of mind for executives in a variety of industries, including turf management, agriculture, and hotel and resorts.

Environmentalists Sound the Alarm on Salton Sea as Oasis is Left in the Dust

More than a century ago, an accidental oasis in the California desert created a popular residential and vacation spot for families.

But over the last few decades, environmental experts say climate change and drought in the Salton Sea have led to a destination that’s been plagued with dust bowls, receding waters and other hazards.

Record Snowpack Conditions in California, Parts of Southwest

After a three-year drought in California and throughout the Southwest, many states throughout the West are measuring record snowpack conditions at NRCS SNOTEL stations and snow courses. Utah especially has seen a benchmark year for snowfall levels throughout the state.

Record Snowpack Conditions in California, Parts of Southwest

After a three-year drought in California and throughout the Southwest, many states throughout the West are measuring record snowpack conditions at NRCS SNOTEL stations and snow courses. Utah especially has seen a benchmark year for snowfall levels throughout the state.

Record snowpack

In California, the statewide snowpack (April 5) was 243% of normal, with the Northern Sierra at 198%, Central Sierra at 242%, and Southern Sierra at 302%. The California Department of Water Resources reported that the 2022-23 season will go down as one of the largest snowpacks on record in California.

In Nevada and Utah, current SWE percentages of median for select basins are as follows: Central Lahontan 273%, Central Nevada Desert Basins 267%, Great Salt Lake 224%, Lower Green 202%, Upper Colorado-Dolores 207%, and Upper Colorado-Dirty Devil 219%, according to the NRCS SNOTEL network.

In Arizona and New Mexico, snowpack levels are above normal, especially in the ranges of northern and central Arizona. In Arizona, the total reservoir system (Salt and Verde River system) is currently 100% full as compared to 72% full at the same time last year, according to the Salt River Project. For the Colorado River system, the U.S. Bureau of Reclamation is reporting (April 4) Lake Mead at 28% full and Lake Powell at 23% full.”

Agricultural weather highlights

“A significant Western warming trend during the weekend and early next week will increase streamflow due to melting snow. On April 10-11, temperatures should briefly top 95°F in lower elevations of the Desert Southwest. Periods of Northwestern precipitation will add to the runoff potential in that region. Meanwhile, little or no precipitation will fall during the next 5 days across a vast swath of the country, including southern California and the Plains, Southwest, Midwest, and Northeast.

Farther south, however, 5-day rainfall could total 1 to 3 inches or more from eastern Texas to the Carolinas, with the bulk of the rain falling by Saturday. The NWS 6- to 10-day outlook for April 11 – 15 calls for the likelihood of below-normal temperatures in California, the Great Basin, and the Northwest, while warmerthan-normal weather will dominate the central and eastern U.S. Meanwhile, above-normal precipitation from the Rockies into the Plains and upper Midwest should contrast with drier-than-normal conditions in the East (excluding Florida’s peninsula) and much of California.”

Dramatic Photos Show How Storms Filled California Reservoirs

Water levels fell so low in key reservoirs during the depth of California’s drought that boat docks sat on dry, cracked land and cars drove into the center of what should have been Folsom Lake.

Those scenes are no more after a series of powerful storms dumped record amounts of rain and snow across California, replenishing reservoirs and bringing an end — mostly — to the state’s three-year drought.

Water Windfall: Key California Reservoir Fills for Just Third Time in 12 years

Five months ago, San Luis Reservoir — the massive lake along Highway 152 between Gilroy and Los Banos — was just 24% full, an arid landscape of cracked mud and lonely boat ramps painfully far away from the dwindling water’s edge.
