DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE BOISE IDAHO
1132 AM MDT FRI OCT 17 2014

...DROUGHT CONDITIONS IMPROVE ACROSS PORTIONS OF EASTERN IDAHO BUT
EXPAND ACROSS WEST CENTRAL IDAHO...

SYNOPSIS...

ABOVE NORMAL PRECIPITATION IN AUGUST AND SEPTEMBER LED TO SOME
IMPROVEMENT IN DROUGHT CONDITIONS ACROSS EASTERN IDAHO. MEANWHILE...
DROUGHT CONDITIONS HAVE EXPANDED ACROSS PORTIONS OF WEST CENTRAL
IDAHO. ELSEWHERE...THERE HAS BEEN LITTLE CHANGE IN THE DROUGHT
SITUATION SINCE MID SEPTEMBER AS SUB-PAR WINTER SNOWPACK...BELOW
NORMAL SPRING PRECIPITATION...AND HOT AND DRY SUMMER CONDITIONS
HAVE ALLOWED DROUGHT TO PERSIST.

ACCORDING TO THE OCTOBER 14 U.S. DROUGHT MONITOR...IN SOUTHERN
IDAHO...MODERATE TO SEVERE DROUGHT (D1 AND D2 CLASSIFICATION) EXISTS
ACROSS MUCH OF THE UPPER SNAKE PLAIN (MAINLY NORTH OF THE SNAKE RIVER)
...THE WOOD RIVER AND LOST RIVER BASINS...ACROSS SOUTH CENTRAL IDAHO
AND OWYHEE COUNTY...EXTENDING NORTH ACROSS THE WEISER RIVER BASIN AND
INTO THE LOWER CLEARWATER BASIN. EXTREME DROUGHT (D3 CLASSIFICATION)
EXISTS ACROSS PART OF THE MAGIC VALLEY IN SOUTH CENTRAL IDAHO...AND
ACROSS A PORTION OF WESTERN OWYHEE COUNTY AND THE LOWER WEISER BASIN.
IN SOUTHEAST OREGON...EXTREME DROUGHT (D3 CLASSIFICATION) EXTENDS
ACROSS HARNEY AND MALHEUR COUNTY AND SOUTHERN BAKER COUNTY...WITH
MODERATE DROUGHT (D2 CLASSIFICATION) ACROSS NORTHERN BAKER COUNTY.

DROUGHT SEVERITY CLASSIFICATION POSSIBLE IMPACTS...
(D1)MODERATE DROUGHT...
SOME DAMAGE TO CROPS. SHORT TERM DRYNESS SLOWING PLANTING AND GROWTH
OF CROPS AND PASTURES. SOME WATER SHORTAGES DEVELOPING OR IMMINENT.
VOLUNTARY WATER USE RESTRICTIONS REQUESTED.

(D2)SEVERE DROUGHT...
CROPS OR PASTURE LOSSES LIKELY. WATER SHORTAGES COMMON. WATER
RESTRICTIONS IMPOSED.

(D3)EXTREME DROUGHT...
MAJOR CROP OR PASTURE LOSSES. WIDESPREAD WATER SHORTAGES OR
RESTRICTIONS.

(D4)EXCEPTIONAL DROUGHT...
EXCEPTIONAL AND WIDESPREAD CROP OR PASTURE LOSSES. SHORTAGES OF
WATER IN RESERVOIRS...STREAMS AND WELLS CREATING WATER EMERGENCIES.

THE SEASONAL DROUGHT OUTLOOK THROUGH JANUARY 31 2015 INDICATES
DROUGHT WILL CONTINUE FOR AREAS THAT ARE ALREADY EXPERIENCING
DROUGHT...AND DROUGHT CONDITIONS ARE LIKELY TO DEVELOP ACROSS
PORTIONS OF NORTHERN IDAHO.

SUMMARY OF REPORTED IMPACTS...

RESIDENTS OF THE WOOD RIVER VALLEY SOUTH OF KETCHUM IDAHO HAVE HAD
LOW WATER PRESSURE AND WELLS RUN DRY DUE TO A LOWERING GROUND WATER
TABLE.

IN SOUTHERN IDAHO MANY SMALLER RESERVOIR SYSTEMS ARE STARTING OFF THE
2015 WATER YEAR WITH WELL BELOW NORMAL STORAGE. THIS INCLUDES LITTLE
WOOD...SALMON FALLS...AND MAGIC RESERVOIRS. IN SOUTHEAST OREGON...
RESERVOIRS HAVE LITTLE OR NO CARRYOVER STORAGE FOR THE NEW WATER YEAR.
OWYHEE RESERVOIR WAS DOWN TO NEAR THE INACTIVE STORAGE POOL FOR THE
SECOND YEAR IN A ROW.

STREAMFLOW AT MANY USGS GAGING STATIONS REMAINS BELOW OR WELL BELOW
NORMAL. FIRE SEASON CONTINUES ACROSS SOUTHEAST OREGON AS WILDLAND
FUELS REMAIN CRITICALLY DRY.

STATE DROUGHT DECLARATIONS HAVE BEEN DECLARED FOR THE FOLLOWING
IDAHO COUNTIES...BUTTE...BLAINE...CLARK...CUSTER...AND LINCOLN.
OREGON STATE DROUGHT DECLARATIONS INCLUDE BAKER...HARNEY AND MALHEUR
COUNTIES. DECLARING A DROUGHT EMERGENCY HELPS COORDINATE LOCAL...
STATE AND FEDERAL EFFORTS TO REDUCE THREATS TO AGRICULTURE...
RECREATION AND NATURAL RESOURCES IN THE COUNTY. THE DECLARATIONS
ALLOW INCREASED FLEXIBILITY IN HOW WATER IS MANAGED TO ENSURE THAT
LIMITED SUPPLIES ARE USED AS EFFICIENTLY AS POSSIBLE. THEY ALSO MAKE
THE COUNTIES ELIGIBLE FOR FEDERAL ASSISTANCE.

AS OF OCTOBER 15...THE U.S. DEPARTMENT OF AGRICULTURE FARM SERVICE
AGENCY PRIMARY DROUGHT DISASTER COUNTIES IN IDAHO INCLUDE BINGHAM...
BLAINE...BONNEVILLE...BUTTE...CAMAS...CANYON...CASSIA...CLARK...
CUSTER...ELMORE...FREMONT...GOODING...JEFFERSON...JEROME...LEMHI...
LINCOLN...MADISON...MINIDOKA...OWYHEE...PAYETTE...POWER...TWIN FALLS
AND WASHINGTON. SOUTHEAST OREGON COUNTIES INCLUDE BAKER...HARNEY AND
MALHEUR. ANY COUNTY DECLARED A PRIMARY OR CONTIGUOUS DISASTER COUNTY
MAKES PRODUCERS IN THAT COUNTY ELIGIBLE FOR CERTAIN EMERGENCY AID.

SITES SECTION BELOW FOR DETAILS.

FAVOR NEAR NORMAL PRECIPITATION FOR SOUTHERN IDAHO AND SOUTHEAST
OREGON...AND BELOW NORMAL PRECIPITATION FOR CENTRAL AND NORTHERN

OVER THE 30 DAY PERIOD FROM SEPTEMBER 15 THROUGH OCTOBER 14...
PRECIPITATION WAS GENERALLY BELOW NORMAL FOR THE NORTHERN HALF OF
IDAHO...AND NORMAL TO ABOVE NORMAL ACROSS THE SOUTHERN HALF OF IDAHO.
IN SOUTHEAST OREGON...PRECIPITATION IN SOUTHERN HARNEY COUNTY AND
