After a devastating drought in 2021 that left Lake Oroville at their lowest water level ever at 628.47 feet, the lake has now seen an intense increase in water levels.
“This past winter storms provided a huge boost to the state water projects, water supply, especially at our largest reservoir at Lake Oroville,” said Ted Craddock, Deputy Director of the State Water Project.
Across the western U.S., many areas received record or near-record amounts of snowpack over the winter. With the spring and summer temperatures melting the abundant snow, a record volume of streamflow has been recorded in several basins in the southwestern U.S., providing more water for the area later into the summer than is typically seen.
The 2022–2023 snow season started off relatively active across the West, with a few modest storms bringing snow accumulations to the mountains in early November. By the start of December, snow water equivalent across much of the region was above normal.
Tulare Lake has sprung back to life, its shoreline rapidly expanding from the runoff of a winter of epic rainstorms and the melting of the massive southern Sierra snowpack.
The lake, which has been mostly dry for decades, now covers miles of rich farmland and is threatening to overwhelm nearby communities.
Records keep piling up across Utah this winter.
Snowpack reached a new high after Thursday night’s storms. The snow water equivalent in Utah, or the amount of water the snow will release when its melts, sits at 26 inches as of Friday morning. That ties with the previous known record of 26 inches set on April 13, 1983, according to Utah Snow Survey data. And with the snow still falling, Friday is likely a new snowpack record.
Western states gripped by persistent drought are unlikely to see any relief in the coming months, as a third year of La Niña weather patterns reduces precipitation in that region, NOAA scientists predicted Thursday.
According to the agency’s 2022-23 Winter Outlook, below-average rainfall and snowpack are expected in a wide stretch of the United States including Southern California, the Southwest, the southern Rockies, the southern Plains, the Gulf Coast and much of the South.
The Department of Water Resources plans to soon drop State Water Project allocations to 0%, following a temporary 15% bump after December storms. DWR Director Karla Nemeth outlined for the State Water Resources Control Board on Tuesday this and other coming actions.
DWR will resubmit a temporary urgency change petition (TUCP) to the board on Friday, after withdrawing the proposal in February. If approved, the emergency regulation will preserve stored supplies for critical human health and safety needs.
When it comes to water conservation, California is burying its head in the winter snow.
Future generations will not look kindly at our leaders’ complete failure to strategically address the state’s water shortages, which will only get worse with climate change.
Two years of some of the worst drought conditions in state history haven’t slowed Big Ag’s demands for more water. Meanwhile, urban users aren’t coming close to meeting Gov. Gavin Newsom’s call to voluntarily cut their water use by 15% from 2020 levels.
The wet winter the American south-west has hoped for as it battles extreme drought and heat is increasingly unlikely to materialize as scientists now predict that a phenomenon known as La Niña will develop for the second year in a row.
The weather system could intensify the worst effects of the drought that much of the region already finds itself in, including higher wildfire risks and water shortages through 2022.
Skiers and snowboarders pray for snow so they can shred the slopes. Climatologists and hydrologists have an entirely different and more critical reason to cross their fingers for the “white gold.”
