DROUGHT INFORMATION STATEMENT...CORRECTED
NATIONAL WEATHER SERVICE LAS VEGAS NV
417 AM PDT SAT MAY 21 2016

CORRECTED TYPOS

...EXTREME TO EXCEPTIONAL DROUGHT CONDITIONS CONTINUE ACROSS WESTERN
SAN BERNARDINO...INYO AND SOUTHWEST ESMERALDA COUNTIES...

SYNOPSIS...ANOTHER ROUND OF SIGNIFICANT PRECIPITATION OCCURRED
DURING THE CLOSING DAYS OF APRIL MAKING APRIL 2016 ONE OF THE
WETTEST MONTHS ON RECORD. LAS VEGAS RECORDED ITS SECOND WETTEST
APRIL, WHILE NEEDLES CA, DEATH VALLEY NP AND BISHOP RECORDED THEIR
FOURTH WETTEST AND BARSTOW ITS FIFTH.

THE WET PATTERN HAS CONTINUED INTO MAY FOR PARTS OF THE REGION,
WHICH HAS BROUGHT SLIGHT IMPROVEMENTS REGARDING SHORT TERM DROUGHT
INDICES.

THE LATEST U.S. DROUGHT MONITOR DEPICTS THAT THE EASTERN SLOPES OF
THE SOUTHERN SIERRA NEVADA REMAIN IN D4, OR EXCEPTIONAL DROUGHT.
EXTREME DROUGHT, OR D3 CONDITIONS, EXISTS ACROSS THE OWENS VALLEY,
WHITE MOUNTAINS, FAR WESTERN ESMERALDA COUNTY, NEVADA AND WESTERN
SAN BERNARDINO COUNTY, CALIFORNIA. SEVERE DROUGHT CONDITIONS, OR D2,
EXIST ACROSS EASTERN ESMERALDA COUNTY, SOUTHWEST NYE COUNTY, EASTERN
INYO AND CENTRAL SAN BERNARDINO COUNTY. THE REST OF EASTERN SAN
BERNARDINO COUNTY, WESTERN MOHAVE COUNTY, CLARK AND SOUTHWEST
LINCOLN COUNTIES ARE IN D1 OR MODERATE DROUGHT CONDITIONS. ACROSS
FAR EASTERN MOHAVE COUNTY AND NORTHEASTERN LINCOLN COUNTY IN NEVADA
CONDITIONS ARE IN D0, OR ABNORMALLY DRY.

DUE TO THE SEVERITY OF THE ONGOING DROUGHT, DROUGHT CONDITIONS ARE
EXPECTED TO PERSIST ACROSS MUCH OF THE AREA.

THE LATEST SEASONAL FORECAST (JUNE THROUGH AUGUST 2016) ISSUED BY
THE CLIMATE PREDICTION CENTER SHOWS THERE ARE EQUAL CHANCES OF
BELOW, NEAR, OR ABOVE NORMAL PRECIPITATION ACROSS THE SOUTHERN GREAT
BASIN AND MOJAVE DESERT. ABOVE NORMAL CONFIDENCE EXISTS DURING THIS
THREE-MONTH PERIOD FOR ABOVE NORMAL TEMPERATURES ACROSS THE ENTIRE
REGION.

SUMMARY OF IMPACTS... AGRICULTURAL

LADWP AND INYO COUNTY SUPERVISORS COULD NOT AGREE ON A PLAN OR
PROPOSED REDUCTIONS TO AGRICULTURAL INTEREST, WHICH MEANS THERE WILL
BE NO CHANGE AND AGRICULTURAL LEASES WILL GET 45,000 ACRE-FEET FOR
IRRIGATION. POTENTIAL AGRICULTURAL LOSERS COULD BE THOSE LEASES
DEPENDENT ON SURFACE WATER.

A CALIFORNIA NUT COMPANY HAS MOVED SOME OPERATIONS TO NORTHWEST
ARIZONA. ONCE FULLY DEVELOPED THE OPERATION COULD DRAW UP TO 24,000
ACRE-FEET A YEAR OUT OF KINGMAN`S AQUIFER.

FEBRUARY 25, 2016 DEPARTMENT OF AGRICULTURE SECRETARIAL DROUGHT
DESIGNATIONS WERE ANNOUNCED. THE U.S. DEPARTMENT OF AGRICULTURE
DESIGNATED CLARK, NYE, LINCOLN AND ESMERALDA COUNTIES IN NEVADA.

DECEMBER 23, 2015 INYO AND SAN BERNARDINO COUNTIES IN CALIFORNIA
WERE DECLARED AS PRIMARY NATURAL DISASTER AREAS DUE TO THE ONGOING
DROUGHT. ALL FARM AND RANCH OPERATORS IN THOSE COUNTIES ARE ELIGIBLE
FOR LOW INTEREST EMERGENCY LOANS FROM THE USDA FARM SERVICE AGENCY,
PROVIDED ELIGIBILITY REQUIREMENTS ARE MET. FARMERS IN ELIGIBLE
COUNTIES HAVE EIGHT MONTHS FROM THE DATE OF THE DECLARATION TO APPLY
FOR LOANS TO HELP COVER PART OF THEIR ACTUAL LOSSES.

IN LATE OCTOBER 2015, WATER FLOWED IN THE LOS ANGELES AQUEDUCT FOR
THE FIRST TIME IN SIX MONTHS AFTER WORKERS REMOVED AN EARTHEN AND
CONCRETE DAM THAT DIVERTED WATER. A DEAL WAS REACHED TO KEEP FLOWS
IN THE OWENS RIVER. THE LOS ANGELES DEPARTMENT OF POWER AND WATER
MOSTLY FULFILLED IRRIGATION CONTRACTS LAST SUMMER IN THE SOUTHERN
END OF THE OWENS VALLEY. DUE TO THE ONGOING DROUGHT, LIVESTOCK HAS
BEEN ESTIMATED TO BE REDUCED BY 40 TO 50 PERCENT IN THE OWENS VALLEY
IN RECENT YEARS.

WATER SUPPLY

THE CURRENT LAKE MEAD WATER ELEVATION ECLIPSED THE LOWEST RECORDED
ELEVATION FROM 2015 AND NOW SETS A NEW RECORD FOR BEING THE LOWEST
SINCE THE RESERVOIR WAS BEING FILLED IN 1937. THE RECORD WILL
CONTINUE TO BE BROKEN AS THE WATER LEVEL IS PROJECTED TO CONTINUE
TO LOWER THROUGH THE END OF JUNE.

THE LATEST U.S. BUREAU OF RECLAMATION GIVES LAKE MEAD ONLY A 37
PERCENT CHANCE OF FALLING INTO SHORTAGE CONDITIONS NEXT YEAR. BUT
THAT CHANCE RISES TO 59 PERCENT IN 2018. THE U.S. BUREAU OF
RECLAMATION DECLARES A SHORTAGE WHENEVER AN ANNUAL STUDY PROJECTS
THE RESERVOIR LEVEL WILL BE LESS THAN 1075 FEET ABOVE SEA LEVEL ON
JANUARY 1. A SHORTAGE COULD FORCE ARIZONA AND CALIFORNIA TO
IMPLEMENT WATER RESTRICTIONS, AND SOME ARIZONA FARMERS WOULD LOSE
THE WATER THAT FLOWS TO THEM THROUGH THE CENTRAL ARIZONA PROJECT
CANAL.

THE NEVADA DROUGHT FORUM, A STATEWIDE PANEL, HAS RECOMMENDED
STATEWIDE WATER METERING, WATER EFFICIENCY STANDARDS FOR NEW
DEVELOPMENT AND ADOPTING TIER RATE STRUCTURES TO PROMOTE
CONSERVATION. THE STATE`S BIGGEST WATER USER, AGRICULTURE, WOULD BE
ENCOURAGED TO USE DRIP IRRIGATION, CROP COVERING AND CONVERT
PLANTINGS TO LESS THIRSTY VARIETIES. THE REPORT ALSO ASKS LOCAL
GOVERNMENTS TO ADDRESS THE ISSUE OF THIRSTY LANDSCAPING REQUIREMENTS
SET BY MANY HOMEOWNERS ASSOCIATIONS. THE SOUTHERN NEVADA WATER
AUTHORITY`S CASH FOR GRASS PROGRAM HAS BEEN VERY SUCCESSFUL AND HAS
REPLACED MORE THAN 173 MILLION SQUARE FEET OF TURF GRASS (MORE THAN
3,000 FOOTBALL FIELDS) WITH LANDSCAPING THAT`S A BETTER FIT FOR
NEVADA`S CLIMATE.

THE VICE PRESIDENT OF SUSTAINABILITY FOR MGM RESORTS INTERNATIONAL
TOLD A PANEL OF THE NEVADA DROUGHT FORUM THAT CONSERVATION EFFORTS
BY THE COMPANY HAVE SAVED ABOUT 2 BILLION GALLONS OF WATER SINCE
2008. THE COMPANY HAS INSTALLED LOW-FLOW FIXTURES AND CHANGED
METHODS FOR DOING LAUNDRY AS PART OF THEIR WATER CONSERVATION
EFFORTS.

GROUND WATER

GREAT BASIN UNIFIED AIR POLLUTION CONTROL DISTRICT BOARD APPROVED A
REVISED STATE IMPLEMENTATION PLAN WHICH WILL HELP BRING OWENS LAKE
INTO COMPLIANCE WITH PM10 REGULATIONS WHILE SAVING WATER.

THE LOS ANGELES DEPARTMENT OF WATER AND POWER IS PLANNING FOUR NEW
PRODUCTION WELLS IN INYO COUNTY. ONE WILL REPLACE A WELL IN LAWS,
TWO IN BISHOP AND ONE IN BELL CANYON WEST OF BIG PINE.

THE NEVADA 78TH LEGISLATURE IS DISCUSSING TWO BILLS RELATED TO
GROUND WATER. SENATE BILL 65 WOULD UPDATE LANGUAGE AFFECTING WATER
RIGHTS AND GROUNDWATER AS WELL AS IMPLEMENT SEVERAL CHANGES TO LAWS
AFFECTING DOMESTIC WELLS. SENATE BILL 81 EXPANDS THE POWER OF THE
STATE`S WATER AUTHORITY TO GOVERN AND MANAGE GROUNDWATER SHORTAGES
IN AREAS SUFFERING FROM SEVERE DROUGHT. BOTH BILLS FAILED TO GET OUT
OF COMMITTEE DURING THE NEVADA 78TH LEGISLATURE.

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 ANGELES DEPARTMENT OF WATER AND POWER AND INYO
COUNTY TO PLAN FOR DRY TIMES.

RECREATION/TOURISM

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.

FIRE WEATHER

THE LATEST SIGNIFICANT WILDLAND FIRE POTENTIAL OUTLOOK FOR THE REST
OF MAY CALLS FOR NORMAL ACTIVITY ACROSS THE ENTIRE AREA.

FOR JUNE ABOVE NORMAL SIGNIFICANT FIRE POTENTIAL WILL DEVELOP IN THE
FINE FUEL AREAS OF FAR SOUTHERN NEVADA AND NORTHWEST ARIZONA.

FOR JULY-AUGUST NORMAL SIGNIFICANT FIRE POTENTIAL WILL OCCUR ACROSS
NORTHWEST ARIZONA AND SOUTHERN NEVADA WHILE ABOVE NORMAL SIGNIFICANT
FIRE POTENTIAL EXPANDS INTO THE SOUTHERN SIERRA NEVADA.

AN AERIAL SURVEY WAS DONE BETWEEN AUGUST 10TH AND 14TH ACROSS THE
SOUTHERN SIERRA NEVADA IN SOUTHWEST INYO COUNTY, CALIFORNIA AND
SHOWED SOME POCKETS IN WHICH GREATER THAN 15 TREES PER ACRE WERE
DYING DUE TO STRESS FROM THE DROUGHT AND OTHER SOURCES SUCH AS BUGS.

WILDLIFE

CONSERVATIONISTS AND GOVERNMENT AGENCIES CAME TOGETHER TO BUILD A
WATER CATCHMENT FACILITY IN THE RUGGED BLACK MOUNTAINS IN WESTERN
MOHAVE COUNTY. THE PROJECT WILL PROVIDE WATER FOR BIGHORN SHEEP AND
OTHER WILDLIFE IN THE AREA.

THE BUREAU OF LAND MANAGEMENT CONDUCTED AN EMERGENCY ROUNDUP OF WILD
HORSES IN THE SPRING MOUNTAINS OF SOUTHERN NEVADA FROM AUGUST 29TH
THROUGH SEPTEMBER 2ND IN THE COLD CREEK AREA. A TOTAL OF 201 HORSES
WERE ROUNDED UP. THE HORSES WERE SUFFERING WEIGHT LOSS DUE TO
STARVING FROM THE DROUGHT, WHICH HAS SIGNIFICANTLY REDUCED THE
AMOUNT OF VEGETATION THAT CAN GROW FOR THE HORSES TO EAT. SOME
HORSES WERE EATING THE BARK OF JOSHUA TREES BECAUSE THEY HAD NOTHING
ELSE TO EAT. A TOTAL OF 28 HORSES FROM THE 201 ROUNDED UP HAD TO BE
EUTHANIZED BECAUSE THEY WERE SO BADLY EMACIATED. THE REMAINING
HORSES WERE TAKEN TO A FACILITY TO BE FED AND NURTURED BACK TO
HEALTH.

PRECIPITATION/TEMPERATURE OUTLOOK...

THE LATEST SEASONAL FORECAST (JUNE THROUGH AUGUST 2016) ISSUED BY
THE CLIMATE PREDICTION CENTER SHOWS THERE ARE EQUAL CHANCES OF
BELOW, NEAR, OR ABOVE NORMAL PRECIPITATION ACROSS THE SOUTHERN GREAT
BASIN AND MOJAVE DESERT. ABOVE NORMAL CONFIDENCE EXISTS DURING THIS
THREE-MONTH PERIOD FOR FOR ABOVE NORMAL TEMPERATURES ACROSS THE
ENTIRE REGION.

HYDROLOGIC SUMMARY AND OUTLOOK...

ABOVE NORMAL PRECIPITATION WHICH HAS OCCURRED IN THE GREEN RIVER AND
YAMPA RIVER BASIN DURING THE FIRST HALF OF MAY HAS LEAD TO MINOR
INCREASES IN THE RUNOFF GUIDANCE. THE COLORADO BASIN WATER SUPPLY
FORECAST FOR APRIL-JULY RUNOFF VOLUMES INTO LAKE POWELL INCREASED
FROM 77 PERCENT TO 84 PERCENT OF AVERAGE AND NOW FORECAST AT 6.0
MAF.

AS OF MAY 19, 2016, LAKE MEAD`S ELEVATION WAS 1074.52 FEET OR 37
PERCENT CAPACITY. LAKE MEAD HAS NOT SEEN LAKE ELEVATIONS THIS LOW
SINCE LAST JUNE AND ALSO SINCE THE RESERVOIR WAS BEING FILLED IN
1937. THE OUTLOOK IS FOR THE WATER ELEVATION TO GO DOWN ABOUT
ANOTHER FOUR FEET BY THE END OF JUNE THEN HOVER BETWEEN 1072 AND
1075 FEET THROUGH THE END OF SEPTEMBER. THE RESERVOIR IS PROJECTED
TO RISE BACK TO AROUND 1080 FEET IN EARLY 2017.

LAKE POWELL`S CURRENT ELEVATION IS 3596.63 OR 47 PERCENT CAPACITY.

DATA FOR RESERVOIRS ACROSS THE REGION (AS OF 5/19/2016)

RESERVOIR                   PERCENT FULL
LAKE MEAD                        37
LAKE MOHAVE                      95
LAKE HAVASU                      96
