DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE BOISE IDAHO
1100 AM MDT WED JUN 3 2015

...DROUGHT PERSISTS ACROSS MOST OF IDAHO AND SOUTHEAST OREGON...

SYNOPSIS...

ACCORDING TO THE MAY 26 U.S. DROUGHT MONITOR...IN IDAHO...MODERATE
TO SEVERE DROUGHT (D1 AND D2 CLASSIFICATION) EXISTS ACROSS THE
PANHANDLE REGION...AND THE SOUTHERN HALF OF THE STATE...EXCEPT FOR
PORTIONS OF FAR EAST AND SOUTHEAST IDAHO. EXTREME DROUGHT (D3
CLASSIFICATION) EXISTS ACROSS MOST OF OWYHEE COUNTY AND MUCH OF
WASHINGTON COUNTY...AND PORTIONS OF CUSTER...BUTTE AND BLAINE
COUNTIES. IN SOUTHEAST OREGON...EXTREME DROUGHT (D3 CLASSIFICATION)
EXTENDS ACROSS HARNEY AND MALHEUR COUNTIES AND SOUTHERN BAKER
COUNTY...WITH SEVERE 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 OUTLOOK INDICATES THAT DROUGHT WILL PERSIST OR
INTENSIFY THROUGH THE SUMMER MONTHS ACROSS SOUTHEAST OREGON AND
IDAHO...EXCEPT FOR EASTERN IDAHO WHERE SOME IMPROVEMENT IS FAVORED.

SUMMARY OF REPORTED IMPACTS...

A NUMBER OF SMALLER RESERVOIRS IN SOUTH CENTRAL IDAHO ARE HOLDING
WELL BELOW AVERAGE STORAGE. IN EASTERN OREGON...THE MAJORITY OF
LARGE RESERVOIRS ARE HOLDING WELL BELOW AVERAGE STORAGE.

MANY FARMERS IN SOUTHEAST OREGON AND PORTIONS OF IDAHO ARE OPERATING
WITH BELOW OR WELL BELOW AVERAGE WATER ALLOTMENTS AND A SHORTENED
IRRIGATION SEASON.

OREGON WATER RESOURCES DEPARTMENT OFFICIALS ARE EXPECTING SEVERAL
EMERGENCY DROUGHT WELLS TO BE DRILLED AGAIN THIS YEAR IN SOUTHEAST
OREGON.

GROUND WATER IS BEING IMPACTED BY LONG TERM DROUGHT WITH OVERALL
DECLINES IN THE SNAKE PLAIN AQUIFER. AQUIFER DECLINES ARE EVIDENT IN
DECREASED REACH GAINS ON THE SNAKE RIVER BETWEEN MILNER AND KING
HILL...IN ADDITION TO FALLING GROUND WATER DEPTHS.

THE LATEST WATER SUPPLY FORECASTS FROM THE NORTHWEST RIVER FORECAST
CENTER INDICATE BETWEEN 40 AND 70 PERCENT OF AVERAGE RUNOFF VOLUMES
ACROSS MOST OF IDAHO FOR THE APRIL THROUGH SEPTEMBER PERIOD. RUNOFF
VOLUMES BETWEEN 20 AND 40 PERCENT OF AVERAGE ARE EXPECTED ACROSS
MOST OF SOUTHEAST OREGON AND PORTIONS OF SOUTHWEST AND SOUTH CENTRAL
IDAHO. FORECASTS AT SOME LOCATIONS IN THE UPPER SNAKE HEADWATERS IN
FAR EASTERN IDAHO CALL FOR 80 TO 90 PERCENT OF AVERAGE...BUT THOSE
ARE THE EXCEPTION.

THE NATIONAL INTERAGENCY FIRE CENTER PREDICTIVE SERVICES INDICATES
THAT SIGNIFICANT WILDLAND FIRE POTENTIAL WILL INCREASE TO ABOVE
NORMAL ACROSS THE IDAHO PANHANDLE IN JUNE. FOR JULY AND AUGUST...
ABOVE NORMAL WILDLAND FIRE POTENTIAL IS EXPECTED FOR NORTHERN AND
CENTRAL IDAHO AND SOUTHEAST OREGON.

STATE DROUGHT EMERGENCY DECLARATIONS HAVE BEEN DECLARED FOR
BLAINE...BUTTE...CUSTER...FREMONT AND LINCOLN COUNTIES IN IDAHO. IN
OREGON...STATE DECLARATIONS HAVE BEEN DECLARED FOR BAKER...HARNEY
AND MALHEUR COUNTIES.

ACCORDING TO THE U.S. DEPARTMENT OF AGRICULTURE FARM SERVICE
AGENCY...AS OF MAY 27 2015...BLAINE...BUTTE...CANYON...CUSTER...
ELMORE...OWYHEE...PAYETTE...TWIN FALLS AND WASHINGTON COUNTIES HAVE
BEEN DESIGNATED AS PRIMARY DROUGHT DISASTER COUNTIES IN IDAHO.
CONTIGUOUS DROUGHT DISASTER COUNTIES IN IDAHO INCLUDE ADA...ADAMS...
BINGHAM...BOISE...CAMAS...CASSIA...CLARK...GEM...GOODING...JEFFERSON
...JEROME...ELMORE...LEMHI...LINCOLN...MINIDOKA...ONEIDA...POWER AND
VALLEY. IN SOUTHEAST OREGON...BAKER...HARNEY AND MALHEUR COUNTIES
ARE PRIMARY DROUGHT DISASTER COUNTIES.

THE SMALL BUSINESS ADMINISTRATION RECENTLY ANNOUNCED THAT NONFARM
BUSINESSES IN A HANDFUL OF SOUTHERN IDAHO COUNTIES ARE NOW ELIGIBLE
TO APPLY FOR LOW INTEREST LOANS TO HELP OFFSET THE COSTS OF
PROLONGED DROUGHT.

THE NATURAL RESOURCES CONSERVATION SERVICE OFFERED AN ADDITIONAL 21
MILLION DOLLARS TO PROTECT WATER AND SOIL QUALITY IN THE MIDST OF
PERSISTENT DROUGHT IN A NUMBER OF STATES...INCLUDING IDAHO AND
OREGON. THE ASSISTANCE WILL ALLOW FARMERS AND RANCHERS TO IMPROVE
GRAZING PASTURES THROUGH IRRIGATION...COVER CROPS AND OTHER MEANS.

CLIMATE SUMMARY...

AS OF JUNE 1 2015...WATER YEAR PRECIPITATION FOR THE MAJORITY OF
IDAHO AND SOUTHEAST OREGON WAS BETWEEN 80 AND 100 PERCENT OF NORMAL.
A PATCHWORK OF AREAS RECEIVED BETWEEN 50 AND 80 PERCENT OF NORMAL...
AND 110 TO 120 PERCENT OF NORMAL.

AVERAGE TEMPERATURES OVER THE 30 DAY PERIOD FROM MAY 3 TO JUNE 1
WERE GENERALLY 2 TO 5 DEGREES ABOVE AVERAGE ACROSS WEST CENTRAL AND
NORTHERN IDAHO AND SOUTHEAST OREGON...AND ABOUT AVERAGE FOR FAR
SOUTHERN AND EASTERN IDAHO.

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 THREE MONTH OUTLOOK FOR JUNE THROUGH AUGUST FAVORS ABOVE NORMAL
TEMPERATURES. PROBABILITIES SLIGHTLY FAVOR ABOVE NORMAL
PRECIPITATION FOR EASTERN IDAHO...WITH EQUAL CHANCES OF EITHER ABOVE
NORMAL...NORMAL...OR BELOW NORMAL PRECIPITATION ELSEWHERE ACROSS
IDAHO AND SOUTHEAST OREGON.

HYDROLOGIC SUMMARY...

AS OF JUNE 1...28 DAY AVERAGE STREAMFLOWS AT USGS GAGING STATIONS
ACROSS NORTHERN AND WEST CENTRAL IDAHO WERE MOSTLY BELOW OR MUCH
BELOW NORMAL...WITH MUCH OF NORTHERN IDAHO BELOW THE 10 PERCENTILE
CLASS FOR LOW FLOWS. ACROSS EAST CENTRAL AND SOUTHERN IDAHO AND
SOUTHEAST OREGON...STREAMFLOWS WERE A MIX OF NORMAL TO MUCH BELOW
NORMAL.

MAJOR RESERVOIR SYSTEMS ACROSS IDAHO WERE GENERALLY HOLDING NEAR
AVERAGE OR ABOVE AVERAGE STORAGE. SOME OF THE SMALLER RESERVOIRS IN
SOUTHERN IDAHO WERE ONLY HOLDING ABOUT 40 TO 70 PERCENT OF AVERAGE.
OVERALL RESERVOIR STORAGE IN SOUTHEAST OREGON WAS WELL BELOW
AVERAGE...WITH THE TWO LARGEST RESERVOIRS...OWYHEE AND WARMSPRINGS
...ONLY HOLDING ABOUT 28 PERCENT OF AVERAGE.
