Snow Surveys Help Plan Snowmelt Runoff Forecasts

/in , , /by /Water News Networkby California Department of Water Resources

The California Department of Water Resources May 1 conducted the fifth snow survey of the season at Phillips Station. The manual survey recorded 59 inches of snow depth and a snow water equivalent of 30 inches, which is 241% of average for this location on May 1.

The last time there was measurable snow at the Phillips snow course on May 1 was 2020, when only 1.5 inches of snow and .5 inches of snow water equivalent was measured.

DWR’s electronic readings from 130 snow sensors placed throughout the state indicate the statewide snowpack’s snow water equivalent is 49.2 inches, or 254% of average for May 1.

The snow water equivalent measures the amount of water still contained in the snowpack and is a key component of DWR’s water supply run-off forecast.

California’s Snowpack Shows Huge Gains from Recent Storms

/in , /by

The snow water equivalent of California’s snowpack is 190% of average for March 3, 2023. After three years of drought, the bountiful winter is good news, but a drier future demands more conservation and innovative solutions for water supply in the Southwestern U.S.

The Department of Water Resources on March 3, conducted the third snow survey of the season at Phillips Station in the Sierra Nevada. The manual survey recorded 116.5 inches of snow depth and a snow water equivalent of 41.5 inches, which is 177% of average for the location on March 3. Snow water equivalent measures the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast.

California’s Snowpack

DWR’s electronic readings from 130 snow sensors placed throughout the state indicate the statewide snowpack’s snow water equivalent is 44.7 inches, or 190% of average for this date.

Recent Storms

“Thankfully the recent storms combined with the January atmospheric rivers have contributed to an above-average snowpack that will help fill some of the state’s reservoirs and maximize groundwater recharge efforts. But the benefits vary by region, and the Northern Sierra, home to the state’s largest reservoir Lake Shasta, is lagging behind the rest of the Sierra,” DWR Director Karla Nemeth said. “It will also take more than one good year to begin recovery of the state’s groundwater basins.”

It Will Take More than a Single Wet Year to Recover Groundwater Levels in Some Parts of the State

Although the statewide snowpack is currently just behind the record snow year of 1982-83, the snowpack varies considerably by region. The Southern Sierra snowpack is currently 209 percent of its April 1 average and the Central Sierra is at 175 percent of its April 1 average. However, the critical Northern Sierra, where the state’s largest surface water reservoirs are located, is at 136 percent of its April 1 average. With one month of the traditional wet season remaining, DWR is providing updated runoff forecasts to water managers and is closely monitoring spring runoff scenarios and river flows to ensure the most water supply benefits from this year’s snowpack while balancing the need for flood control.

“The recent storms over the past week broke a month-long dry spell in a dramatic way,” said DWR’s Snow Surveys and Water Supply Forecasting Unit Manager Sean de Guzman. “We are hopeful that we will see more cold storms to add to our snowpack for the next month and help set up a long, slow melt period into spring.”

‘Good News’ but Conservation Remains Critical

“The results of today’s snow survey is good news for the state’s water supply, especially for those parts of the state that rely on snowmelt as their primary source of water,” said San Diego County Water Authority Water Resources Manager Jeff Stephenson. “The above average snowpack levels come after three consecutive years of drought that resulted in below normal water levels at the state’s major reservoirs. For the San Diego region, the recent local storms allow residents and businesses to turn off sprinklers and irrigation for at least several weeks, if not longer. This allows the region to keep more water in local reservoirs for use later in the year.”

California’s Snowpack and a Hotter, Drier Climate

“Despite the recent wet weather and the region’s diverse water supply portfolio, the long-term forecast of a hotter, drier climate, for the Southwest U.S., means that water use efficiency remains a key part of saving our most precious resource, in wet or dry years,” added Stephenson.

Stephenson said that there are rebates and other free services available to residents and businesses of San Diego County that can help conserve water and save money.

Airborne Snow Observatory Surveys

To ensure water supply managers have the most current forecasts of snowpack runoff, DWR is utilizing the best available technology to collect the most accurate snow measurements. DWR’s Snow Surveys and Water Supply Forecasting Unit is utilizing Airborne Snow Observatory (ASO) surveys across 12 of California’s major snow-producing watersheds to collect data on the snowpack’s density, depth, reflectiveness, and other factors down to a 3-meter resolution. These flights, which utilize LiDAR and imaging spectrometer technology, provide DWR with more information on water content than ever before, which is then fed into advanced physically based and spatially explicit models to generate the most accurate water supply runoff forecasts possible. These forecasts are used to develop the Bulletin 120 for forecasted spring run-off to determine water allocation and stream flows for the benefit of the environment.

Groundwater Basins ‘Slower to Recover’ From Drought

While winter storms have helped the snowpack and reservoirs, groundwater basins are much slower to recover. Many rural areas are still experiencing water supply challenges, especially communities that rely on groundwater supplies which have been depleted due to prolonged drought. It will take more than a single wet year for groundwater levels to substantially improve at a statewide scale. Drought impacts also vary by location and drought recovery will need to be evaluated on a regional scale and will depend on local water supply conditions.

On February 13, Governor Newsom issued an Executive Order directing state agencies to review and provide recommendations on the state’s drought response actions by the end of April, including the possibility of terminating specific emergency provisions that are no longer needed, once there is greater clarity about the hydrologic conditions this year.

Save Our Water

Californians should still continue to use water wisely so that we can have a thriving economy, community, and environment. DWR encourages Californians to visit SaveOurWater.com for water saving tips and information as more swings between wet and dry conditions will continue in the future.

DWR conducts five media-oriented snow surveys at Phillips Station each winter near the first of each month, January through April and, if necessary, May. The next survey is tentatively scheduled for April 3.

Snow Survey: Good Start but Drought Relief Depends on Coming Months

Snow Survey: Good Start but Drought Relief Depends on Coming Months

The California Department of Water Resources first manual snow survey of the season Tuesday at Phillips Station recorded 55.5 inches of snow depth and a snow water equivalent of 17.5 inches, which is 177% of average for the location. The snow water equivalent measures the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast. Statewide the snowpack is 174% of average for this date.

Survey: December storms delivered big snow totals

California is expected to see continued rain and snow over the next seven days, with the threat of flooding in parts of California. Conditions so far this season have proven to be strikingly similar to last year when California saw some early rainstorms and strong December snow totals only to have the driest January through March on record.

“The significant Sierra snowpack is good news but unfortunately these same storms are bringing flooding to parts of California,” said DWR Director Karla Nemeth. “This is a prime example of the threat of extreme flooding during a prolonged drought as California experiences more swings between wet and dry periods brought on by our changing climate.”

One year ago, the Phillips survey showed the seventh highest January measurements on record for that location. However, those results were followed by three months of extremely dry conditions and by April 1 of last year, the Phillips survey measurements were the third lowest on record.

More telling than a survey at a single location are DWR’s electronic readings from 130 stations placed throughout the state. Measurements indicate that statewide, the snowpack’s snow water equivalent is 17.1 inches, or 174%  of average for January 3.

Opportunities to save more water

“After three consecutive years of drought, the recent series of storms is a good start to the season,” said Jeff Stephenson, water resources manager with the San Diego County Water Authority. “However, we had a similarly strong early winter last year, which did not continue. While the Water Authority and its 24 member agencies have worked and continue to develop diverse water supply sources, there are still opportunities, including rebates, to save more water.”

In San Diego County, watersmartsd.org, provides sources of residential and business rebates, including indoor and outdoor incentives, and free landscape makeover classes. 

Stephenson added that the region has reduced its reliance on imported water supplies, including from the Sacramento-San Joaquin Bay Delta, which means more of that source is available for other parts of California.

Strong start but “a long way to go”

The January 2023 manual snow survey results are similar to results in 2013 and 2022 when the January 1 snowpack was at or above average conditions, only for dry weather to set in and lead to drought conditions by the end of the water year (September 30).

In 2013, the first snow survey of the season also provided promising results after a wet December similar to today’s results. However, the following January and February were exceptionally dry, and the water year ended as the driest on record, contributing to a record-breaking drought. In 2022, record-breaking December snowfall was again followed by the driest January through March period on record.

“Big snow totals are always welcome, but we still have a long way to go before the critical April 1 total,” said DWR’s Snow Surveys and Water Supply Forecasting Unit Manager Sean de Guzman. “It’s always great to be above average this early in the season, but we must be resilient and remember what happened last year. If January through March of 2023 turn out to be similar to last year, we would still end the water year in severe drought with only half of an average year’s snowpack.”

Sierra snowpack supplies 30% of California’s water

On average, the Sierra snowpack supplies about 30% of California’s water needs and is an important factor in determining how DWR manages the state’s water resources. Its natural ability to store water is why the Sierra snowpack is often referred to as California’s “frozen reservoir.” A below-average snowpack impacts water users across the state, putting further stress on the environment and critical groundwater supplies.

Due to these increasing swings from dramatically wet to dry conditions, Governor Newsom’s recently released “California’s Water Supply Strategy, Adapting to a Hotter, Drier Future” calls for investing in new projects and technologies that will modernize how the state manages water.

Current climate research indicates the state will see bigger swings from extreme heat and dry conditions to larger and more powerful storms that deliver temporary large boosts to the state snowpack as well as flood risk.

DWR conducts five snow surveys at Phillips Station each winter near the first of each month, January through April and, if necessary, May. The next survey is tentatively scheduled for February 1.
