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.

Department of Water Resources (DWR) hydrologists today announced that water content in California's mountain snowpack is 165 percent of the April 1 full season average. "Recent storms have significantly contributed to the above-average snowpack, helping to stabilize California's water supply for the year," said DWR Director Mark Cowin. "While this is beneficial for California's farms' businesses and communities, we remind residents to practice sensible water use and conservation as we transition to warmer weather."

Our up-and-down cycles -- drought followed by flood threats -- remind us that assuring an adequate water supply in California is always a juggling act, and we can't afford to forget the lessons of conservation even in brief periods of plenty."

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.
