DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE BOISE IDAHO
205 PM MST THU JAN 22 2015

...DROUGHT PERSISTS ACROSS MUCH OF SOUTHERN IDAHO AND SOUTHEAST
OREGON...

SYNOPSIS...

ONLY MINOR CHANGE HAS OCCURRED TO THE DROUGHT STATUS ACROSS IDAHO
AND SOUTHEAST OREGON SINCE THE BEGINNING OF THE 2015 WATER YEAR.

ACCORDING TO THE JANUARY 20 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 NEAR THE OREGON BORDER
ACROSS WESTERN WASHINGTON AND WESTERN ADAMS COUNTIES. EXTREME
DROUGHT (D3 CLASSIFICATION) EXISTS ACROSS PART OF THE MAGIC VALLEY
IN SOUTH CENTRAL IDAHO...AND ACROSS A PORTION OF WESTERN OWYHEE
COUNTY AND FAR SOUTHWEST WASHINGTON COUNTY. IN SOUTHEAST OREGON...
EXTREME DROUGHT (D3 CLASSIFICATION) EXTENDS ACROSS HARNEY AND
MALHEUR COUNTIES AND SOUTHERN BAKER COUNTY...WITH MODERATE TO SEVERE
DROUGHT (D1 AND 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 MARCH 31 2015 INDICATES DROUGHT
WILL CONTINUE FOR AREAS THAT ARE ALREADY EXPERIENCING DROUGHT...AND
SOME EXPANSION OF DROUGHT CONDITIONS IS LIKELY IN NORTHERN IDAHO.

SUMMARY OF REPORTED IMPACTS...

POOR RESERVOIR STORAGE CARRYOVER...LOW STREAMFLOWS...AND LAGGING
SNOWPACK IN SOME AREAS HAVE AFFECTED WATER SUPPLY EXPECTATIONS FOR
THE COMING GROWING SEASON. THE NORTHWEST RIVER FORECAST CENTER
INDICATES BETWEEN 50 TO 75 PERCENT OF NORMAL WATER VOLUMES DURING
THE APRIL THROUGH SEPTEMBER PERIOD FOR SEVERAL LOCATIONS IN SOUTH
CENTRAL AND SOUTHWEST IDAHO...AS WELL AS IN SOUTHEAST OREGON. THE
OWYHEE PROJECT HAS BEEN ONE OF THE HARDEST HIT DUE TO CONSECUTIVE
YEARS OF DROUGHT. THE WATER SUPPLY FORECAST FOR BELOW OWYHEE DAM IS
FOR ONLY 47 PERCENT OF NORMAL FOR THE APRIL THROUGH SEPTEMBER
PERIOD.

ACCORDING TO THE U.S. DEPARTMENT OF AGRICULTURE FARM SERVICE
AGENCY...IN 2014 THE FOLLOWING 24 COUNTIES IN IDAHO WERE DESIGNATED
AS PRIMARY DROUGHT DISASTER COUNTIES...ADAMS...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.
SEE THE U.S. DEPARTMENT OF AGRICULTURE WEB SITE IN THE RELATED WEB
SITES SECTION BELOW FOR DETAILS.

CLIMATE SUMMARY...

AS OF JANUARY 21...PRECIPITATION FOR THE 2015 WATER YEAR WAS BELOW
AVERAGE FOR MOST OF EASTERN IDAHO AND EXTREME SOUTH CENTRAL
IDAHO...AS WELL AS ACROSS MOST OF MALHEUR COUNTY AND WESTERN BAKER
COUNTY IN OREGON. ELSEWHERE...PRECIPITATION WAS NEAR OR ABOVE
NORMAL.

NRCS SNOTEL DATA FOR IDAHO INDICATED AROUND 70 PERCENT OF NORMAL
SNOWPACK FOR THE SPOKANE BASIN AND PANHANDLE REGION...AND ABOUT 75
PERCENT OF NORMAL FOR THE WEISER AND OWYHEE BASINS. OTHERWISE...THE
REST OF IDAHO SNOWPACK RANGED FROM ABOUT 85 TO 120 PERCENT OF
NORMAL. ACROSS SOUTHEAST OREGON...SNOWPACK WAS 75 TO 85 PERCENT OF
NORMAL.

TEMPERATURES IN DECEMBER 2014 WERE SEVERAL DEGREES ABOVE NORMAL...
ESPECIALLY ACROSS SOUTHERN IDAHO AND SOUTHEAST OREGON. IN JANUARY
2015...TEMPERATURES HAVE GENERALLY BEEN ABOVE NORMAL EXCEPT FOR SOME
OF THE LOW ELEVATIONS WHERE INVERSIONS HAVE KEPT TEMPERATURES BELOW
NORMAL.

BELOW IS A LIST OF PRECIPITATION DATA FOR SELECTED LOCATIONS IN
IDAHO AND SOUTHEAST OREGON FOR THE 2015 WATER YEAR.

PRECIPITATION AND TEMPERATURE OUTLOOK...

THE OUTLOOK FOR THE REMAINDER OF JANUARY FAVORS ABOVE NORMAL
TEMPERATURES AND BELOW NORMAL PRECIPITATION ACROSS THE REGION.

THE THREE MONTH OUTLOOK FOR FEBRUARY THROUGH APRIL FAVORS ABOVE
NORMAL TEMPERATURES. MEANWHILE...PROBABILITIES FAVOR BELOW NORMAL
PRECIPITATION FOR NORTHERN IDAHO...AND EQUAL CHANCES OF EITHER ABOVE
NORMAL...NORMAL...OR BELOW NORMAL PRECIPITATION ELSEWHERE.

HYDROLOGIC SUMMARY...

MAJOR RESERVOIR SYSTEMS ACROSS IDAHO WERE GENERALLY HOLDING NEAR
AVERAGE OR ABOVE AVERAGE STORAGE. A FEW OF THE SMALLER RESERVOIRS IN
SOUTHERN IDAHO WERE ONLY HOLDING 40 TO 70 PERCENT OF AVERAGE. MAJOR
RESERVOIRS IN SOUTHEAST OREGON WERE WELL BELOW AVERAGE.

AS OF JANUARY 22...28 DAY AVERAGE STREAMFLOWS AT USGS GAGING
STATIONS IN SOUTHERN IDAHO WERE BELOW NORMAL ALONG PORTIONS OF THE
SNAKE RIVER...PORTNEUF RIVER...BIG WOOD AND BIG LOST RIVERS. IN
SOUTHEAST OREGON...STREAMFLOWS WERE BELOW NORMAL ON THE MALHEUR
RIVER. ELSEWHERE ACROSS IDAHO AND SOUTHEAST OREGON....STREAMFLOWS
WERE GENERALLY NORMAL OR ABOVE NORMAL.
