...DROUGHT STATE OF EMERGENCY CONTINUES FOR CALIFORNIA...

SYNOPSIS...
GOVERNOR BROWN DECLARED A DROUGHT STATE OF EMERGENCY FOR CALIFORNIA 
ON JANUARY 17, 2014. ON APRIL 25, 2014 GOVERNOR BROWN ISSUED A 
PROCLAMATION ON THE CONTINUATION OF THE DROUGHT EMERGENCY. THIS 
EXECUTIVE ORDER STRENGTHENED THE STATE'S ABILITY TO MANAGE WATER AND 
HABITAT EFFECTIVELY IN DROUGHT CONDITIONS AND CALLED FOR ALL 
CALIFORNIANS TO REDOUBLE THEIR EFFORTS TO CONSERVE WATER. ACCORDING 
TO THE U.S. DROUGHT MONITOR, MOST OF INLAND CALIFORNIA IS IN 
D4-EXCEPTIONAL DROUGHT WITH D3-EXTREME DROUGHT OVER THE EXTREME  
NORTHERN SACRAMENTO VALLEY. THE DROUGHT CLASSIFICATIONS ARE DUE IN 
LARGE PART TO THE PRECIPITATION DEFICIT, LOW RESERVOIR LEVELS AND 
LOCAL IMPACTS. 

SEVERAL COUNTIES HAVE ISSUED LOCAL DROUGHT EMERGENCY PROCLAMATIONS 
IN RESPONSE TO THE DETERIORATING SITUATION INCLUDING EL DORADO, 
GLENN, LAKE, SAN JOAQUIN, SHASTA, SUTTER, TUOLUMNE, PLUMAS AND YUBA. 
THREE CITIES CONTINUE IN A DROUGHT EMERGENCY, LIVE OAK IN SUTTER 
COUNTY AND BOTH LODI AND RIPON IN SAN JOAQUIN COUNTY. SEVERAL 
SPECIAL DISTRICTS HAVE ISSUED LOCAL EMERGENCY DECLARATIONS INCLUDING 
LAKE DON PEDRO COMMUNITY SERVICES DISTRICT, NEVADA IRRIGATION 
DISTRICT, PLACER COUNTY WATER AGENCY, TWAIN HARTE COMMUNITY SERVICES 
DISTRICT,  MOUNTAIN HOUSE COMMUNITY SERVICE DISTRICT AND TUOLUMNE 
UTILITY DISTRICT. COUNTY DROUGHT TASK FORCES HAVE BEEN ESTABLISHED 
IN BUTTE, LAKE, NEVADA, PLACER, PLUMAS, SACRAMENTO, SAN JOAQUIN, 
STANISLAUS, SUTTER, TEHAMA, TUOLUMNE AND YOLO COUNTIES TO COORDINATE 
LOCAL DROUGHT RESPONSE. THE GOVERNORS DROUGHT TASK FORCE MEETS DAILY 
TO TAKE ACTIONS THAT CONSERVE WATER AND COORDINATE STATE RESPONSE TO 
THE DROUGHT.

LOCAL WATER AGENCIES HAVE ENACTED MANDATORY OR VOLUNTEER WATER 
RESTRICTIONS ACROSS THE STATE. FOR MORE INFORMATION ABOUT SPECIFIC 
LOCAL WATER AGENCIES USAGE RESTRICTIONS PLEASE VISIT

SUMMARY OF IMPACTS...

GOVERNOR BROWN HAS ORDERED MANDATORY WATER REDUCTIONS OF 25 PERCENT 
IN CITIES AND TOWNS ACROSS THE STATE. THIS IS THE FIRST TIME IN 
STATE HISTORY THAT A GOVERNOR HAS IMPLEMENTED SUCH REDUCTIONS. 

THE STATE WATER BOARD ADOPTED EMERGENCY REGULATIONS REQUIRING AN  
IMMEDIATE 25 PERCENT REDUCTION IN OVERALL POTABLE URBAN WATER USE 
STATEWIDE.

THE COMMUNITY OF LAKE DON PEDRO(STANISLAUS COUNTY) IS EXPECTED TO RUN 
OUT OF WATER BY MID-SUMMER. 

AGRICULTURAL IMPACTS INCLUDE SOME FARMERS REMOVING TREES FROM THEIR 
ORCHARDS OR LEAVING THEIR LAND UNPLANTED. SUTTER COUNTY HAS REPORTED 
THE LOSS OF 1100 AGRICULTURAL JOBS RELATED TO THE DROUGHT.

MANY COUNTIES ARE UTILIZING CDAA (CA DISASTER ASSISTANCE ACT) MONIES 
TO SUPPORT THE DROUGHT SUCH AS SUPPLYING HOMES WHO'S WELLS HAVE 
RUN DRY WITH WATER FOR DRINKING AND SANITATION.

THE STATE WATER BOARD ADOPTED EMERGENCY REGULATIONS TO REDUCE URBAN 
OUTDOOR WATER USE. THIS ESTABLISHES INDIVIDUAL TEMPORARY 
PROHIBITIONS LIKE LAWN-WATERING THAT CAUSES RUNOFF...HOSING DOWN 
DRIVEWAYS AND USING DECORATIVE FOUNTAINS THAT DON'T RECIRCULATE 
WATER. VIOLATIONS MAY BE PUNISHABLE BY FINES UP TO $500.  

ALL THE COUNTIES WITHIN NORTHERN INTERIOR CALIFORNIA REMAIN 
DESIGNATED AS PRIMARY NATURAL DISASTER AREAS BY THE U.S. DEPARTMENT 
OF AGRICULTURE DUE TO DAMAGES AND LOSSES CAUSED BY THE DRY 
CONDITIONS. GOVERNMENT PROGRAMS INCLUDE ASSISTANCE PAYMENTS AND 
EMERGENCY LOANS FOR FARMERS AND RANCHERS.

THE CALIFORNIA STATE RESOURCES BOARD IS CONSIDERING EXTENDING 
CURRENT WATER RESTRICTIONS AND ADOPTING ADDITIONAL LIMITS ON WATER 
USE AS THE STATE HEADS INTO ITS FOURTH YEAR OF DROUGHT. AMONG THE 
POSSIBLE MEASURES ARE REQUIRING RESTAURANTS CUSTOMERS TO REQUEST 
WATER AND HOTELS GUESTS TO ASK FOR NEW TOWELS AND SHEETS.

ONE SALINITY BARRIER IS BEING PUT INTO PLACE IN THE DELTA TO HELP 
KEEP THE BRACKISH WATER FARTHER WEST. THIS IS THE FIRST BARRIER PUT 
IN PLACE SINCE 1976-77.

CLIMATE SUMMARY...
2014 WAS THE THIRD DRY WATER YEAR IN A ROW FOR NORTHERN CALIFORNIA. 
THE NORTHERN SIERRA 8 STATION PRECIPITATION INDEX THROUGH MAY 31ST 
IS AT 74% OF NORMAL. THE 5 STATION SAN JOAQUIN BASIN INDEX LAGS 
BEHIND AT 45% OF NORMAL. VERY LITTLE IN THE WAY OF SNOW PACK REMAINS 
FOR INPUT INTO RIVER BASINS. 

PRECIPITATION/TEMPERATURE OUTLOOK... 
THE RAINY SEASON HAS COME TO A CLOSE FOR NORTHERN CALIFORNIA. BRIEF 
MOISTURE SURGES CAN STILL LEAD TO SMALL AMOUNTS OF PRECIPITATION 
MAINLY OVER THE MOUNTAINS DURING THE SUMMER. AN EL NINO ADVISORY HAS 
BEEN ISSUED BY THE CLIMATE PREDICTION CENTER FOR THE SUMMER FOR A 
WEAK EL NINO. EL NINO IS A WINTER TIME SIGNAL AND IS NOT A GOOD 
INDICATOR OF INCREASED SUMMER PRECIPITATION. THERE IS AN 80% CHANCE 
OF THE EL NINO LASTING THROUGH THE WINTER 2015. THE LONG TERM 
CLIMATE OUTLOOK FORECAST SHOWS NO CLEAR SIGNAL FOR ABOVE...BELOW OR 
NORMAL PRECIP THROUGH THE FALL. TEMPERATURES ARE EXPECTED TO BE 
ABOVE NORMAL THROUGH THE SUMMER. 

HYDROLOGIC SUMMARY AND OUTLOOK...
RESERVOIR STORAGE FOR THE SACRAMENTO RIVER BASIN IS AT 61% OF 
CAPACITY.

NEXT ISSUANCE DATE...
THE NEXT SCHEDULED PRODUCT WILL BE ISSUED IN LATE JUNE OR SOONER 
IF NECESSARY IN RESPONSE TO SIGNIFICANT CHANGES IN CONDITIONS.
