...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, MUCH OF INLAND CALIFORNIA IS IN 
D4-EXCEPTIONAL DROUGHT WITH D3-EXTREME DROUGHT OVER THE NORTHERN 
SACRAMENTO VALLEY AND NORTHERN SIERRA. 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 GLENN, LAKE, 
SAN JOAQUIN, SHASTA, SUTTER, TUOLUMNE 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...

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.

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 TO REDUCE URBAN 
OUTDOOR WATER USE ON JULY 15. 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 DEPARTMENT OF SOCIAL SERVICES HAS PROVIDED OVER 
192,700 BOXES OF FOOD TO JUST OVER 74,000 HOUSEHOLDS TO DATE FOR 
COUNTIES IMPACTED BY THE DROUGHT.  THIS FOOD AID, ENABLED BY 
EMERGENCY DROUGHT LEGISLATION PASSED IN MARCH, IS TARGETED TOWARD 
RESIDENTS ECONOMICALLY IMPACTED BY THE DROUGHT. THE DEPARTMENT IS 
WORKING WITH LOCAL FOOD BANKS TO ENSURE THAT EACH FOOD BANK HAS A 
PLAN TO OUTREACH TO THOSE MOST IMPACTED BY THE DROUGHT.

ON JANUARY 23 2015...GOVERNOR BROWN AND THE STATE WATER 
RESOURCES BOARD GAVE NOTICE OF SURFACE WATER SHORTAGE AND 
POTENTIAL FOR CURTAILMENT OF WATER RIGHTS DIVERSIONS FOR 2015.

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.

CLIMATE SUMMARY...
2014 WAS THE THIRD DRY WATER YEAR IN A ROW FOR NORTHERN CALIFORNIA. 
ALTHOUGH...SIGNIFICANT RAIN FELL OVER PORTIONS OF INTERIOR NORTHERN 
CALIFORNIA IN DECEMBER...JANUARY WAS A RECORD DRY MONTH FOR MOST OF 
THE AREA. FEBRUARY WAS MORE THAN 50% BELOW NORMAL FOR MOST AREAS 
WITH THE EXCEPTION BEING NORTHERN SHASTA COUNTY WHICH WAS NEAR 
NORMAL. RAINFALL DEFICITS REMAIN LARGE. MARCH HAS BEEN BELOW NORMAL 
FOR CENTRAL AND SOUTHERN AREAS OF THE SACRAMENTO VALLEY WITH NEAR 
NORMAL PRECIPITATION OVER SHASTA COUNTY. PRECIPITATION HAS BEEN 
BELOW NORMAL FOR THE SIERRA DURING MARCH. SMALL IMPROVEMENTS FROM 
EARLY SEASON RAINFALL HAVE BEEN MOSTLY ERASED AND THE NORTHERN 
SIERRA 8 STATION PRECIPITATION INDEX THROUGH APRIL 3RD IS AT 83% OF 
NORMAL. THE 5 STATION SAN JOAQUIN BASIN INDEX LAGS BEHIND AT 40% OF 
NORMAL. IN EVEN WORSE SHAPE IS THE SNOW PACK WHICH IS A DISMAL 5% OF 
APRIL NORMAL. THIS IS THE LOWEST SNOW PACK FOR THIS TIME OF YEAR IN 
THE RECORDED HISTORY OF OBSERVATIONS. 

PRECIPITATION/TEMPERATURE OUTLOOK... 
THE RAINY SEASON IS COMING TO A CLOSE FOR NORTHERN CALIFORNIA WHICH 
TYPICALLY LASTS THROUGH APRIL BUT SOMETIMES INTO MAY...ESPECIALLY 
OVER EXTREME NORTHERN AREAS. AN EL NINO ADVISORY HAS BEEN ISSUED BY 
THE CLIMATE PREDICTION CENTER FOR THE SPRING FOR A WEAK EL NINO. 
THERE IS A 50-60% CHANCE OF THE WEAK EL NINO LASTING THROUGH THE  
SUMMER 2015. HISTORICALLY, WEAK EL NINO EVENTS ARE NOT STRONG 
SIGNALS OF NORTHERN CALIFORNIA PRECIPITATION. THE LONG TERM CLIMATE 
OUTLOOK FORECAST SHOWS NO CLEAR SIGNAL FOR ABOVE...BELOW OR NORMAL 
PRECIP THROUGH JUNE. A BRIEF CHANGE IN THE PATTERN TO WETTER 
CONDITIONS IS LIKELY THROUGH APRIL 15TH. TEMPERATURES ARE EXPECTED 
TO BE ABOVE NORMAL THROUGH AT LEAST JUNE.
