...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 BUTTE, EL 
DORADO, GLENN, LAKE, SAN JOAQUIN, SHASTA, SUTTER, TUOLUMNE, PLUMAS 
AND YUBA. 

SEVERAL CITIES CONTINUE IN A DROUGHT EMERGENCY, LIVE OAK IN SUTTER 
COUNTY, LODI, MANTECA AND RIPON IN SAN JOAQUIN COUNTY, 
PORTOLA(PLUMAS COUNTY) AND WEST SACRAMENTO.
 
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

SUMMARY OF IMPACTS... 

NUMEROUS LARGE AND DESTRUCTIVE WILDFIRES CONTINUE OVER THE STATES AS 
A DIRECT RESULT OF THE PROLONGED DRY CONDITION OF VEGETATION. AS A 
RESULT GOVERNOR BROWN HAS ISSUED A STATE OF EMERGENCY. 

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.

SAN LUIS RESERVOIR IN SAN JOAQUIN VALLEY NOW FLOWS BACKWARD FOR THE 
FIRST TIME IN ITS 64 YEAR HISTORY. THIS MAY COST POWER COMPANY'S 
MILLIONS OF DOLLARS.

A FULLY OCCUPIED HOUSING DEVELOPMENT APPROX 50 HOMES IN ARBUCKLE, 
COLUSA COUNTY HAS A DRY WELL.

SENIOR WATER RIGHTS HOLDERS ARE NOW FACING WATER CURTAILMENT.

THE DROUGHT'S ECONOMIC TOLL TO CALIFORNIA IS ESTIMATED AT 2.7 
BILLION IN 2015 AND WILL ELIMINATE MORE THAN 21,000 JOBS PER REPORT 
OF THE UC DAVIS CENTER FOR WATERSHED SCIENCES.

NASA SATELLITE DATA SHOWS LAND IN THE SAN JOAQUIN VALLEY IS SINKING 
FASTER THAN EVER BEFORE, NEARLY 2 INCHES PER MONTH IN SOME LOCATIONS 
DUE TO INCREASED WELL WATER PUMPING.


CLIMATE SUMMARY...
2014 WAS THE THIRD DRY WATER YEAR IN A ROW FOR NORTHERN CALIFORNIA. 
THE NORTHERN SIERRA 8 STATION PRECIPITATION INDEX THROUGH AUG 30TH 
IS AT 75% OF NORMAL. THE 5 STATION SAN JOAQUIN BASIN INDEX LAGS 
BEHIND AT 47% OF NORMAL.  

PRECIPITATION/TEMPERATURE OUTLOOK...                              
THE DRY SEASON CONTINUES OVER NORTHERN CALIFORNIA AND WILL LAST 
THROUGH OCTOBER. BRIEF MOISTURE SURGES CAN STILL LEAD TO SMALL 
AMOUNTS OF PRECIPITATION MAINLY OVER THE MOUNTAINS DURING THE LATE 
SUMMER AND TROUGHS OVER THE PACIFIC NORTHWEST CAN SOMETIMES BRING 
LIGHT RAIN TO THE NORTHERN MOUNTAINS. AN EL NINO ADVISORY HAS BEEN 
ISSUED BY THE CLIMATE PREDICTION CENTER LASTING THROUGH THE UPCOMING 
WINTER FOR A POTENTIALLY STRONG EL NINO. THERE IS AN 90% CHANCE OF 
THE EL NINO LASTING THROUGH THE WINTER 2015. EVEN STRONG EL NINO'S 
ARE NOT A GUARANTEE OF ABOVE NORMAL PRECIPITATION. THE LONG TERM 
CLIMATE OUTLOOK SHOWS A SLIGHT SIGNAL FOR ABOVE PRECIPITATION OVER 
THE SAN JOAQUIN VALLEY MOST OF THE SACRAMENTO VALLEY AND THE SIERRA 
DURING THE WINTER. TEMPERATURES ARE EXPECTED TO BE ABOVE NORMAL 
THROUGH THE WINTER. 

HYDROLOGIC SUMMARY AND OUTLOOK... RESERVOIR STORAGE FOR THE 
SACRAMENTO RIVER BASIN IS AT 65% OF CAPACITY.

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