CA DWR Snow Pack Survey 2/3

DWR:

SACRAMENTO, Calif. – The Department of Water Resources (DWR) today conducted the second manual snow survey of the season at Phillips Station. The manual survey recorded 63 inches of snow depth and a snow water equivalent (SWE) of 17 inches, which is 93 percent of average for this location. The SWE measures the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast.

“The recent blast of winter weather was a welcome sight, but it was not enough to offset this winter’s dry start,” said DWR Director Karla Nemeth. “While there is still a chance we will see additional storms in the coming weeks, the Department and other state agencies are preparing for the potential for a second consecutive year of dry conditions.”

Statewide snow survey measurements reflect those dry conditions. Measurements from DWR’s electronic snow survey stations indicate that statewide the snowpack’s SWE is 12.5 inches, or 70 percent of the February 3 average, and 45 percent of the April 1 average. April 1 is typically when California’s snowpack is the deepest and has the highest SWE.

Fall 2020 was extremely dry, especially in the Sierra Nevada, and follows last year’s below-average snow and precipitation. With only a couple months remaining in California’s traditional wet season, Californians should look at ways to reduce water use at home.

DWR:

SACRAMENTO, Calif. – The Department of Water Resources (DWR) today conducted the fourth snow survey at the Phillips Station snow course. The manual survey recorded 49.5 inches of snow depth and a snow water equivalent (SWE) of 21 inches, which is 83 percent of average for this location. The SWE measures the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast.

Measurements from DWR’s electronic snow survey stations indicate that statewide the snowpack’s SWE is 16.5 inches, or 59 percent of average for the date. April 1 is typically when California’s snowpack is the deepest and has the highest SWE.

“While there is some snow on the ground today at Phillips Station, there is no doubt California is in a critically dry year. State agencies, water suppliers and Californians are more prepared than ever to adapt to dry conditions and meet the challenges that may be ahead,” said DWR Director Karla Nemeth. “With climate change impacting how precipitation falls in California, ongoing water efficiency and long-term efforts like recycling water, capturing stormwater, and planting water-friendly landscapes are essential to securing California’s water future.”

While the Southern Sierra remains well below average for both rain and snow, the picture is somewhat different in the Northern and Central part of the state where California typically receives 75 percent of the State’s annual precipitation. The few storms that impacted California this year have been colder, bringing more snow than rain. This is a positive sign for the Sierra snowpack which accounts for 30 percent of California’s fresh water supply in an average year. For Water Year 2021, the snowpack in the Northern and Central Sierra peaked at 70 percent of average, however rain is below 50 percent of average, which ties this year for the third driest year on record.

The severity of dry conditions is particularly evident in the Feather River watershed where water levels at Lake Oroville, the State Water Project’s largest reservoir, are currently at 53 percent of average. Statewide, following a below average 2020 water year, California’s major reservoirs are at just 50 percent of overall capacity. The amount of water expected to enter California’s reservoirs when the snowpack melts is projected to be just 58 percent of average.

With dry conditions continuing to impact California’s water supply, DWR recently announced an adjustment to the State Water Project allocation for 2021. The department now expects to deliver 5 percent of requested supplies this year, down from the initial allocation of 10 percent announced in December.

California is better prepared for drought than in the past. Following the 2012-2016 drought, DWR enacted many programs focused on managing the state’s water through a strategic, integrated approach with a strong emphasis on water use efficiency and conservation. The State provides assistance and tools to local water agencies to help them reduce their drought vulnerability. DWR’s Water Use and Efficiency Branch (WUE) provides agencies and individuals with assistance for improving water use efficiency and developing and meeting efficient water use requirements.

How about some new dam projects!

Maybe Russ meant "damn projects?" Hmmmm... wonder if that's going to be automatically censored...

Build more Dams already. Raise those that can be raised.
