DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE SACRAMENTO CA
600 PM PDT FRI JUN 03 2016

...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. GOVERNOR BROWN STATED
THAT CALIFORNIANS STEPPED UP DURING THIS DROUGHT AND SAVED MORE
WATER THAN EVER BEFORE...BUT NOW WE KNOW DROUGHT IS BECOMING A
REGULAR OCCURRENCE AND WATER CONSERVATION MUST BE A PART OF OUR
EVERYDAY LIFE.

ACCORDING TO THE U.S. DROUGHT MONITOR, AREAS OF INLAND CALIFORNIA
NORTH OF HIGHWAY 50 WERE IN D1 TO D2 MODERATE/SEVERE DROUGHT...WITH
AREAS SOUTH OF HIGHWAY 50 D3/D4 EXTREME/EXCEPTIONAL. THE DROUGHT
CLASSIFICATIONS ARE DUE IN LARGE PART TO THE LONG TERM PRECIPITATION
DEFICIT, DRYING WELLS AND LOCAL IMPACTS. 

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 
HTTP://WWW.ACWA.COM/CONTENT/LOCAL-DROUGHT-RESPONSE. 

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.

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.

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.

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

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...2015 WAS THE FOURTH DRY WATER YEAR IN A ROW FOR
NORTHERN CALIFORNIA. 2016 WATER YEAR WHICH BEGAN OCT 1ST HAS BEEN
MIXED WITH ABOVE NORMAL RAINFALL FOR NORTHERN AND MOUNTAIN AREAS AND
BELOW FOR MANY VALLEY LOCATIONS. THE NORTHERN SIERRA 8 STATION
PRECIPITATION INDEX THROUGH JUN 3RD IS AT 119% OF NORMAL.
THE 5 STATION SAN JOAQUIN BASIN INDEX IS AT 102% OF NORMAL. 

PRECIPITATION/TEMPERATURE OUTLOOK...                          

THE WET SEASON HAS DRAWN TO A CLOSE OVER NORTHERN CALIFORNIA WITH
VERY LITTLE RAINFALL EXPECTED THROUGH THE SUMMER. THE CURRENT EL
NINO WILL LIKELY TRANSITION TO NEUTRAL CONDITIONS DURING THE EARLY
SUMMER 2016 WITH A 75 PERCENT CHANCE FOR LA NINA CONDITIONS TO
DEVELOP DURING THE FALL AND WINTER.

THE LONG TERM CLIMATE OUTLOOK SHOWS NO CLEAR SIGNAL FOR ABOVE/BELOW
OR NORMAL PRECIPITATION THROUGH 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 107% OF AVERAGE.

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