Cooperative Snow Surveys Website - Snowpack

California Cooperative Snow Surveys As the successful use of snow surveys in the forecasting of runoff became known, several water agencies began independent snow survey programs. After a few years, theses agencies, and the State of California, recognized both the inherent value that such information could have for water users throughout the State and the need for centralized coordination of the snow survey program. Following some sporadic attempts at statewide involvement, in 1929 the State Legislature established a statewide program that has continued to this day.

05/01/2014 - Year's Final Snow Survey Comes up Dry
SACRAMENTO ? Today?s final snow survey of the year found more bare ground than snow as California faces another long, hot summer after a near-record dry winter.
Today's manual and electronic readings recorded the statewide snowpack's water content ? which normally provides about a third of the water for California?s farms and cities -- at a mere --18 percent of average for the date.
Just as telling was the April 1 survey that found water content at only 32 percent of average at the time of year it normally is at its peak before it begins to melt into streams and reservoirs with warming weather.

04/28/2014 - Season's Final Snow Survey Scheduled Thursday
SACRAMENTO ? Department of Water Resources snow surveyors Thursday will take the year's final measurement of water content in the Sierra snowpack. Near-record low numbers are expected as California's drought pushes through its third year.
The May 1 survey is taken after the snowpack ? which normally peaks in early April -- has begun to melt into streams and reservoirs with warming spring weather. Statewide, the April 1 "peak" this year was a dismal 32 percent of average water content for the date.

02/27/2014 - Snow Survey Finds Slightly Increased Water Content
SACRAMENTO ? Storms are lightly blanketing the Sierra with fresh snow, but Department of Water Resources (DWR) snow surveyors today reported that snowpack water content remains far below what will be needed by cities and farms this summer. "We welcome the late storms but they are not enough to end the drought,? said DWR Director Mark Cowin. ?We can?t control the weather but we can control the amount of water we use. This drought is a wake-up call that we all have to take water conservation seriously and make it a way of life."

02/25/2014 - DWR's Third Snow Survey of Winter Set for February 27
SACRAMENTO ? Department of Water Resources surveyors hope to find a bit more snow when they go into the mountains Thursday to measure snowpack water content. But water managers say this week's expected storms will do little more than dent California?s persistent drought conditions. "California is in the grip of a game-changing drought and we have no idea how long it will last," said DWR Director Mark Cowin. "We already have been forced to set State Water Project allocations at zero, and we have nothing but more hard choices ahead until we see significant new amounts of rain and snow. One choice we all must make is to get serious about conserving water in our homes and places of work and make it a lifelong habit."

02/13/2014 - DWR releases weekly update of the Bulletin 120: Water Conditions in California
The February 11th update to the Bulletin 120: Water Conditions in California is now available. The forecast includes observed conditions through the morning of February 11, 2014.
The forecasts will be posted on the California Cooperative Snow Surveys website - Water Conditions in California - B120

02/07/2014 - DWR to release first water supply forecasts of the year
The February 1st Bulletin 120: Water Conditions in California and the Sacramento (SVI) and San Joaquin Valley (SJI) Water Year Type Index forecasts will be available Monday, February 10, 2014. Bulletin 120 is a publication issued four times a year, in the second week of February, March, April, and May by the California Department of Water Resources. It contains forecasts of the volume of seasonal runoff from the state's major watersheds, and summaries of precipitation, snowpack, reservoir storage, and runoff in various regions of the State.
This Sacramento Valley Water Year Type Index (40-30-30), originally specified in the 1995 SWRCB Water Quality Control Plan, is used to determine the Sacramento Valley water year type as implemented in SWRCB D-1641. Year types are set by first of month forecasts beginning in February. Final determination is based on the May 1 50% exceedence forecast. Likewise, the San Joaquin Valley Water Year Type Index (60-20-20) is used to determine the San Joaquin Valley water year type. Final determination for San Joaquin River flow objectives is based on the May 1 75% exceedence forecast.

01/30/2014 - Snow Surveyors Find Sparse Snowpack Drought Retains Grip on California
SACRAMENTO -- Freshly fallen snow from late-arriving storms brightened the scenery but did not end California?s drought. The winter?s second snow survey today found far too little water in the still scant snowpack. ?This winter remains dry, making it very unlikely our record drought will be broken this year,? said DWR Director Mark Cowin. ?Now more than ever, we all need to save every drop we can in our homes and places of work.? Manual and electronic readings today record the snowpack?s statewide water content at only 12 percent of average for this time of year. That is a mere 7 percent of the average April 1 measurement when the snowpack normally is at its peak before melting into streams and reservoirs to provide about a third of the water used by California's cities and farms.

01/28/2014 - DWR's Second Snow Survey of Winter Set for January 30
SACRAMENTO ? As winter slips away, the Department of Water Resources (DWR) expects to find far less snow that normal for the date when it conducts its second snow survey of the winter on Thursday. California?s stubborn drought, pushing into its third year, has left the Sierra largely bare of snow and the state?s reservoirs low. Storms finally breaking through a coastal high pressure ridge largely blamed for dry conditions are expected to bring some snow to higher elevations before Thursday?s snow survey, but not enough to dent the drought. Still, conditions may be better than on January 3 when the first survey of the season found more bare ground than snow.

12/30/2013 - Winter's First Snow Survey Set for January 3
SACRAMENTO ? With water officials bracing for a possible third consecutive dry year in California, the Department of Water Resources (DWR) will conduct the season?s first snow survey on January 3. This survey's results likely will be far different than last winter?s initial readings which showed water content in the snowpack at 150 percent of normal for the date, just as California was turning dry after wet storms in November and December. Today's scant snowpack dramatically illustrates the result of the near-record dry weather we have had since last January. Statewide electronic readings indicate that today?s snowpack water content is only 20 percent of normal for the date.

12/17/2013 - Department of Water Resources Names Drought Management Team to Prepare for a Dry 2014
SACRAMENTO ? The Department of Water Resources (DWR) has mobilized a new drought management effort to prepare for and reduce potential impacts of what is expected to be a third straight dry year in 2014. DWR Director Mark Cowin said the department is focusing its personnel and programs ?to offset potentially devastating impacts to citizen health, well-being and our economy.? Cowin has appointed Bill Croyle to lead the effort as department drought manager. Croyle has 30 years of experience in water operations, including seven years as DWR?s flood operations chief and 23 years with the Central Valley Regional Water Quality Control Board.

03/28/2013 - Snow Survey Dramatically Shows Dry Conditions
SACRAMENTO  Snow surveyors today reported that water content in Californias snowpack is only 52 percent of normal, with the spring melt season already under way. With most of the wet season behind us, this is more gloomy news for our summer water supply, said DWR Director Mark Cowin. After a record dry January and February in much of the state, DWR on Friday decreased its water delivery estimate, or allocation, from 40 to 35 percent of requested amounts from the State Water Project (SWP). The 29 public agencies that purchase SWP water requested just over four million acre-feet of water for this calendar year. Collectively, the agencies supply more than 25 million Californians and nearly a million acres of irrigated agriculture. Pumping restrictions imposed this winter to protect Delta smelt and salmon are another reason for the low water delivery estimate.

03/27/2013 - Season's Fourth Snow Survey Scheduled for Thursday
SACRAMENTO -- The Department of Water Resources (DWR) will conduct the season's next-to-last snow survey this Thursday, March 28. It is expected that the manual measurements will confirm electronic readings showing that snowpack water content is well below normal for the date. Remote sensors today indicate that statewide, snowpack water content is 54 percent of average for the date. That is also 54 percent of the average April 1 reading when the snowpack normally is at its peak before the spring melt. The snowpack normally provides about a third of California's water as it melts into streams, reservoirs and aquifers in spring and early summer. November and December storms built a heavy snowpack early this season, but conditions since have been unusually dry.

02/28/2013 - Third 2013 Snow Survey Shows Continuing Dry Conditions
SACRAMENTO -- Snow surveyors today confirmed that water content in the mountain snowpack is well below normal for the date. The snowpack hasnt actually lost much water content since the seasons first survey on January 2, when it was 134 percent of normal for that date, but it hasnt continued to build as winter has deepened because of the continuing warm weather that set in after the storms of late November and early December. In other words, the snowpack has not kept pace with the calendar. As a result, todays snowpack water content is only 66 percent of average for this time of year, and only 57 percent of the average April 1 reading, when the snowpack normally is at its peak before beginning to melt into the states streams, reservoirs and aquifers. The snowpack  often called Californias frozen reservoir  normally provides about a third of the water for Californias farms and communities.

02/26/2013 - Third 2013 Snow Survey Scheduled for February 28
SACRAMENTO  The Department of Water Resources (DWR) will conduct this winters third snow survey on Thursday, February 28. It is expected that manual measurements of snowpack water content will corroborate the low electronic readings from remote sensors up and down the states mountain ranges. Electronic readings today indicate that statewide, water content in the snowpack is only 68 percent of normal for the date, and 58 percent of the average April 1 measurement when the snowpack is normally at its peak before the spring melt. Surveyors from DWR and cooperating agencies will fan out to numerous sites for the third of five manual snow surveys made each winter to forecast the amount of frozen water that will trickle into streams, reservoirs and aquifers when the snow melts this spring and early summer.

01/29/2013 - Second Snow Survey of 2013 Shows Below Normal Conditions
SACRAMENTO -- Snow surveyors today reported that water content in Californias mountain snowpack is below average for the date. Manual and electronic readings today record the snowpacks statewide water content at 93 percent of average for this time of year. That is 55 percent of the average April 1 measurement, when the snowpack is normally at its peak before the spring melt. The snowpack normally provides about a third of the water for Californias homes, farms and industries as it slowly melts into streams, reservoirs and aquifers in the spring and early summer. Were still seeing decent snowpack conditions due to storms in late November and early December, said DWR Director Mark Cowin. Those early season storms also erased the deficit in our reservoir storage, but relatively dry weather this month is once again a reminder that the weather is unpredictable and we must always practice conservation.

01/24/2013 - Second 2013 Snow Survey Scheduled for January 29
SACRAMENTO -- The Department of Water Resources (DW R) will conduct this winters second snow survey on January 29. The second snow survey each season is the first comprehensive look at the snowpack in which all snow courses active in the statewide network, approximately 250, are measured manually. In comparison, just 15 to 20 courses typically are manually measured in the initial surveys. The manual surveys  conducted on or about the first of the month from January through May  supplement and check the accuracy of real-time electronic sensors up and down the states mountain ranges. One focus of attention on January 29 will be the manual survey scheduled for 11 a.m. off Highway 50 near Echo Summit. This combined with the information gathered from all the manual surveys and the electronic sensors will give a comprehensive picture of statewide snowpack conditions.

Manual and electronic readings today record the snowpacks statewide water content at 134 percent of average for this time of year. That is 49 percent of the average April 1 measurement, when the snowpack is normally at its peak before the spring melt. The snowpack normally provides about a third of the water for Californias homes, farms and industries as it slowly melts into streams, reservoirs and aquifers in the spring and early summer. We are off to a good water supply start for the new year, but we have to remember that we have seen wet conditions suddenly turn dry more than once, said DWR spokesman Ted Thomas. We know from

12/31/2012 - First 2013 Snow Survey Scheduled for January 2

SACRAMENTO -- The Department of Water Resources (DWR) will conduct this winters first snow survey on January 2. A traditional center of attention will be the manual survey scheduled for 11 a.m. off Highway 50 near Echo Summit. This and other manual and electronic readings up and down the state will determine the amount of water in the early winter snowpack. Thanks to early season storms, electronic readings indicate that statewide, todays snowpack water content is 146 percent of normal for the date. The snowpack normally provides about a third of the water for Californias households, farms and industries as it slowly melts into streams, reservoirs and aquifers in spring and early summer.

05/23/2012 - Wet April Boosts State Water Project Deliveries
The Department of Water Resources (DWR) today estimated it will be able to deliver 65 percent of requested State Water Project (SWP) water this year. This is up from the 60 percent delivery estimate -- or allocation -- announced on April 16. Originally, DWR projected in November that it would be able to supply 60 percent of the slightly more than 4 million acre-feet of SWP water requested, but a dry December, January and February dropped that figure to 50 percent. A wet March and above-average reservoir storage boosted the allocation back up to 60 percent in April, and today's increase to 65 percent is due to April's wetter-than-usual weather. A 65 percent allocation is not unusually low.

05/01/2012 - Final Snow Survey of 2012 Shows Low Water Content

Manual and electronic readings today show that California's drier than usual mountain snowpack is steadily melting with warming spring weather. Statewide, snowpack water content is only 40 percent of normal for the date, and was only 55 percent of normal the first of April, the time of year when it is historically at its peak. "The fact that we just had a dry winter right after an unusually wet season last year shows that we must be prepared for all types of weather," said DWR Director Mark Cowin. "Reservoir storage will mitigate the impact of dry conditions on water supply this summer, but we have to plan for the possibility of a consecutive dry year in 2013, both by practicing conservation, continuing to develop alternative local water supplies, and working toward improved water storage and conveyance."

04/27/2012 - Final Snow Survey of 2012 Set for May 1
The Department of Water Resources (DWR) will conduct this year's fifth and final snow survey on May 1. One focus of media attention will be the manual survey scheduled for 11 a.m. off Highway 50 near Echo Summit about 90 miles east of Sacramento. Manual surveys up and down the state will be combined with electronic readings from remote sensors to indicate the rate at which the mountain snowpack is melting into the state's streams, reservoirs and aquifers. The snowpack normally provides about a third of the water for California's homes, industry and agriculture. April 2 measurements showed that water content in the winter snowpack -- often called California's frozen reservoir -- was only 55 percent of normal at the time of year when it historically is at its peak. Today, it is 46 percent of normal.

Department of Water Resources snow surveyors today confirmed that California's mountain snowpack holds far less water than normal for this time of year. Manual and electronic readings show that statewide, snowpack water content is only 30 percent of historic readings for the date. That is a mere 26 percent of the average April 1 measurement, when the snowpack is normally at its peak before it begins to melt with rising spring temperatures.

Manual and electronic readings record the snowpack's statewide water content at only 37 percent of normal for the date. That is just 23 percent of the average April 1 reading, when the snowpack normally is at its peak before the spring melt. "So far, we just haven't received a decent number of winter storms," said DWR Director Mark Cowin. "We have good reservoir storage thanks to wet conditions last year, but we also need more rain and snow this winter."

05/02/2011 - DWR Announces Results of Final Snow Survey of 2010-2011 Season
Manual and electronic readings today show that California's near-record snowpack is slowly melting with warming spring weather. But snowpack water content is still 144 percent of the April 1 full season average. Today's readings will help hydrologists forecast spring and summer snowmelt runoff into rivers and reservoirs. The melting snow supplies approximately one-third of the water used by Californians. "All indications are that we're moving toward summer with a good water supply for our farms and cities," said DWR Director Mark Cowin. "We must be aware, however, that California can quickly turn from wet to dry, and we can't afford to forget the lessons of conservation that we learned in the 2007-2009 drought."

04/28/2011 - DWR's Fifth and Final Snow Survey of the 2010-2011 Season in Place for Next Week
The Department of Water Resources (DWR) will conduct its fifth and final manual snow survey of the season, Monday, May 2, at 11 a.m. off Highway 50, near Echo Summit. Electronic readings currently indicate that snowpack water content has dipped, as anticipated, to 151 percent of the April 1, full season average. May snow survey figures are normally lower than April readings, and used to forecast the spring and summer runoff. April 1 readings recorded 165 percent of the April 1 full season average, due to heavy storms in late February and March.

01/28/2011 - DWR Announces Results of Second Snow Survey of 2010-2011 Season
Manual and electronic readings today indicate that California?s mountain snowpack is holding above average water content despite a dry January. Statewide, real-time sensors show that snowpack water content is 78 percent of the April 1 seasonal average. This compares to an average reading of 55 percent for today?s date. The above-average readings are due to heavy storms in October, November and December. January so far has recorded only about 13 percent of average precipitation for the month. ?We are still optimistic for a good water supply, but realize that we can come up short any given year,? said DWR Director Mark Cowin. ?Our unpredictable weather and delivery restrictions make it clear that conservation must always be one of our top priorities."DWR estimates it will be able to deliver 60 percent of requested State Water Project (SWP) water this year. The estimate will be adjusted as hydrologic and regulatory conditions continue to develop.
