DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE LAS VEGAS NV
615 PM PST MON DEC 22 2014

...WINTER STORMS KEEP THE DROUGHT FROM DETERIORATING BUT IMPROVEMENT
WILL TAKE A LONG TIME TO COME...

SYNOPSIS...AFTER A VERY DRY FALL ACROSS THE AREA, DECEMBER 2014 HAS
FEATURED SEVERAL STORM SYSTEMS THAT HAVE RESULTED IN WIDESPREAD
PRECIPITATION FINALLY FALLING ACROSS THE AREA. IN ADDITION,
LINGERING LOW-LEVEL MOISTURE HAS PERSISTED FOR MUCH OF THE FIRST
TWO-THIRDS OF DECEMBER WHICH HAS KEPT VEGETATION FROM DRYING OUT.
THE STORM SYSTEM OF DECEMBER 2ND THROUGH THE 4TH BROUGHT THE MOST
SIGNIFICANT PRECIPITATION TOTALS TO THE MOJAVE DESERT AND SOUTHERN
GREAT BASIN SINCE THE 2014 NORTH AMERICAN MONSOON SEASON DID BACK IN
SEPTEMBER. ALTHOUGH THIS RECENT BATCH OF STORMS HAS BROUGHT NEEDED
PRECIPITATION, IT IS NOT ENOUGH TO ALLOW FOR ANY IMPROVEMENT WITH
THE ONGOING DROUGHT. HOWEVER, IT WILL HELP DETER ANY FURTHER
DEGRADATION OF THE DROUGHT.

THE LATEST U.S. DROUGHT MONITOR DEPICTS NO DEGRADATION OR
IMPROVEMENT THIS MONTH. EXTREME DROUGHT, OR D3 CONDITIONS, EXISTS
ACROSS ALL OF ESMERALDA, CENTRAL NYE, SMALL PORTION OF SOUTHWEST
LINCOLN AND NORTHWEST CLARK COUNTIES IN NEVADA AS WELL AS FAR
NORTHWESTERN SAN BERNARDINO COUNTY ALL BUT FAR SOUTHEAST INYO COUNTY
IN CALIFORNIA. SEVERE DROUGHT CONDITIONS, OR D2, EXIST ACROSS THE
REMAINDER OF SOUTHWEST LINCOLN COUNTY AND CLARK COUNTY IN NEVADA,
CENTRAL SAN BERNARDINO COUNTY AND NORTHEAST MOHAVE COUNTY. DUE TO
THE SEVERITY OF THE ONGOING DROUGHT, DROUGHT CONDITIONS ARE EXPECTED
TO PERSIST ACROSS THE AREA DESPITE THE 90 DAY OUTLOOK FOR JANUARY,
FEBRUARY AND MARCH FROM THE CLIMATE PREDICTION CENTER SHOWING A
GREATER PROBABILITY OF ABOVE NORMAL PRECIPITATION FOR SOUTHERN
CALIFORNIA, SOUTHERN NEVADA AND NORTHWEST ARIZONA. THERE IS A
GREATER PROBABILITY OF ABOVE NORMAL TEMPERATURES ACROSS THE AREA AS
WELL.

SUMMARY OF IMPACTS...

RECREATION/TOURISM

HISTORIC LOW LAKE LEVELS IN THE EASTERN SLOPES OF INYO COUNTY
AFFECTED RESORTS THAT CATER TO FISHERMEN AND OTHERS THAT ENJOY
RECREATIONAL ACTIVITIES. THE SOUTH LAKE BOAT LANDING WAS CLOSED FOR
THE SUMMER SEASON DUE TO THE DROUGHT. BISHOP CREEK WILL FLOW AT 30
TO 35 CFS THROUGH THE END OF 2014 WITH ABOUT 12 CFS BEING
CONTRIBUTED BY RELEASES FROM LAKE SABRINA.

THE LOW LAKE LEVELS IN LAKE MEAD CONTINUE TO IMPACT RECREATIONAL
BOATING CHANNELS BY REDUCING AREAS THAT BOATS CAN PASS THROUGH. THE
FALLING LAKE LEVEL HAS RESULTED IN THE CONTINUED CLOSURE OF THE ECHO
BAY MARINA AND BOAT LAUNCH RAMP AT ECHO BAY.

NATURAL SPRINGS IN THE SHEEP MOUNTAIN RANGE IN SOUTHERN NEVADA HAVE
RUN DRY IN SOME INSTANCES FORCING HIKERS TO HAVE TO BRING WATER WITH
THEM.

NATURAL SPRING THAT PROVIDED WATER TO THE MOUNT CHARLESTON YOUTH
CAMP HAS STOPPED FLOWING. CLARK COUNTY WILL NEED TO SPEND ABOUT
$250,000 FOR WATER SHIPMENTS OVER A 38 WEEK PERIOD.

FIRE WEATHER

NORMAL SIGNIFICANT WILDFIRE POTENTIAL IS EXPECTED FOR THE REST OF
DECEMBER AND JANUARY FOR INYO COUNTY AND THE DESERTS OF SAN
BERNARDINO COUNTY, CALIFORNIA.

AGRICULTURAL

THE UNITED STATES DEPARTMENT OF AGRICULTURE DESIGNATED CLARK, NYE,
LINCOLN AND ESMERALDA COUNTIES IN NEVADA, MOHAVE COUNTY IN ARIZONA
AND INYO AND SAN BERNARDINO COUNTIES IN CALIFORNIA AS PRIMARY
NATURAL DISASTER AREAS DUE TO THE RECENT DROUGHT. ALL FARM AND RANCH
OPERATORS IN THOSE COUNTIES ALL QUALIFY FOR LOW INTEREST EMERGENCY
LOANS FROM THE USDA FARM SERVICE AGENCY, PROVIDED ELIGIBILITY
REQUIREMENTS ARE MET.

LIVESTOCK PRODUCERS USING RANGELAND MAY NEED TO PROVIDE SUPPLEMENTAL
FEED FOR CATTLE. SOME RANCHERS IN NORTHWEST ARIZONA, THE OWENS
VALLEY OF CALIFORNIA AND LINCOLN COUNTY, NEVADA HAVE INCREASED WATER
HAULS FOR LIVESTOCK.

WILDLIFE

IN LINCOLN COUNTY, ESPECIALLY IN NORTHERN PORTIONS, WILD HORSES HAVE
BEGUN TO COME ONTO GRAZING LANDS AND EAT FORAGE INTENDED FOR GRAZING
CATTLE AND OTHER WILDLIFE. THIS HAS RESULTED IN DAMAGE TO SOME
GRAZING LANDS.

GROUND WATER

INYO COUNTY SUPERVISORS PASSED A THREE-PAGE DROUGHT PROCLAMATION FOR
INYO COUNTY. THEY NOTED THE SERIOUSNESS OF THE SITUATION BY
POINTING OUT THE VERY LOW SNOWPACK IN THE SOUTHERN SIERRA, DRY WELLS
AROUND BISHOP AND CONCERNS ABOUT USE OF WATER ON THE DRY LAKE AND
THE NEED FOR LOS ANGLES DEPARTMENT OF WATER AND POWER AND INYO
COUNTY TO PLAN FOR DRY TIMES.

CLIMATE SUMMARY...

THE FALL SEASON HAS BEEN CATEGORIZED BY A LACK OF RAIN AND SNOW
WHILE TEMPERATURES HAVE BEEN WARMER THAN NORMAL.

PERCENT CAPACITY. THE BUREAU OF RECLAMATION HAS PROJECTED TO RELEASE
9.0 MAF FROM LAKE POWELL IN WATER YEAR 2015...UP FROM THE 7.48 MAF
