DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE BOISE IDAHO
345 PM MDT THU SEP 18 2014

...DROUGHT CONDITIONS REMAIN ACROSS MUCH OF SOUTHERN IDAHO AND
SOUTHEAST OREGON...

SYNOPSIS...

MODERATE TO EXTREME DROUGHT REMAINS ACROSS MUCH OF SOUTHERN IDAHO
AND SOUTHEAST OREGON. WET CONDITIONS ACROSS SOUTH CENTRAL AND
SOUTHEAST IDAHO IN AUGUST PROVIDED SOME RELIEF AS RECORD RAINFALL
OCCURRED IN AREAS AND THE DEMAND FOR IRRIGATION WATER DECREASED.
HOWEVER...TYPICAL HOT AND DRY SUMMER WEATHER...FOLLOWING BELOW
NORMAL SPRING PRECIPITATION AND SUB-PAR WINTER SNOWPACK...SET THE
STAGE FOR DROUGHT TO PERSIST HEADING INTO AUTUMN.

ACCORDING TO THE SEPTEMBER 18 U.S. DROUGHT MONITOR...IN SOUTHERN
IDAHO...MODERATE TO SEVERE DROUGHT (D1 AND D2 CLASSIFICATION) EXISTS
ACROSS THE SNAKE PLAIN...THE WOOD RIVER AND LOST RIVER BASINS...
ACROSS ALL OF SOUTH CENTRAL IDAHO AND OWYHEE COUNTY...EXTENDING INTO
THE WEISER RIVER 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.

SUMMARY OF IMPACTS...

IN SOUTHERN IDAHO AND SOUTHEAST OREGON...MANY RESERVOIRS BEGAN THE
GROWING SEASON WITH WELL BELOW NORMAL STORAGE. AS A RESULT...WATER
WAS SHUT OFF EARLIER THAN NORMAL ON MANY CANALS SYSTEMS. RESERVOIRS
SYSTEMS IN SOUTHERN IDAHO IMPACTED BY LOW STORAGE AND EARLY
IRRIGATION WATER SHUTOFF INCLUDE LITTLE WOOD...SALMON FALLS AND
MAGIC. SOUTHEAST OREGON RESERVOIRS INCLUDE OWYHEE...WARM SPRINGS...
BEULAH...BULLY CREEK...UNITY AND PHILLIPS. CARRYOVER STORAGE FOR THE
2015 WATER YEAR WILL BE BELOW NORMAL FOR MANY RESERVOIRS...
ESPECIALLY ACROSS SOUTHEAST OREGON.

IN THE BURNT RIVER VALLEY IN SOUTHERN BAKER COUNTY...NATURAL SPRINGS
CONTINUE TO DRY-UP AND SOILS ARE EXTREMELY DRY TO A LARGE DEPTH. SOME
RESIDENTS HAVE STATED THAT THIS IS THE DRIEST THEY HAVE EVER SEEN IT
AND LIKEN IT TO DUST BOWL CONDITIONS.

STREAMFLOW AT MANY USGS GAGING STATIONS REMAINS WELL BELOW NORMAL
ACROSS SOUTHERN IDAHO AND SOUTHEAST OREGON. SUMMER TEMPERATURES HAVE
BEEN ABOVE NORMAL...ESPECIALLY ACROSS SOUTHEAST OREGON...LEADING TO
INCREASED STRESS ON VEGETATION AND INCREASED WILDFIRE SUSCEPTIBILITY.

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
COUNTY. 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 SEPTEMBER 17...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. SEE THE U.S. DEPARTMENT OF AGRICULTURE WEB SITE IN THE
RELATED WEB SITES SECTION BELOW FOR DETAILS.

PRECIPITATION AND TEMPERATURE OUTLOOK...

OUTLOOK FOR OCTOBER...PROBABILITIES FAVOR ABOVE NORMAL TEMPERATURES
FOR SOUTHEAST OREGON AND SOUTHWEST IDAHO...AND NEAR NORMAL
TEMPERATURES ELSEWHERE IN IDAHO. PROBABILITIES FAVOR NEAR NORMAL
PRECIPITATION ACROSS THE REGION.

OUTLOOK FOR NOVEMBER THROUGH JANUARY...PROBABILITIES FAVOR ABOVE
NORMAL TEMPERATURES ACROSS THE REGION. NORMAL PRECIPITATION IS
FAVORED FOR EASTERN IDAHO...WITH BELOW NORMAL PRECIPITATION
ELSEWHERE IN IDAHO AND FOR SOUTHEAST OREGON.

HYDROLOGIC SUMMARY...

OVER THE 30 DAY PERIOD FROM AUGUST 19 THROUGH SEPTEMBER 17...
PRECIPITATION WAS NORMAL TO ABOVE NORMAL ACROSS THE SOUTH CENTRAL AND
EASTERN IDAHO...AND THE IDAHO PANHANDLE. BELOW NORMAL PRECIPITATION
OCCURRED ELSEWHERE ACROSS IDAHO AND SOUTHEAST OREGON.

USGS 28 DAY AVERAGE STREAMFLOWS AS OF SEPTEMBER 18 WERE NORMAL TO
ABOVE NORMAL FOR MOST OF NORTHERN AND CENTRAL IDAHO...AND ON THE
MAINSTEM SNAKE RIVER ABOVE AMERICAN FALLS AND THE BEAR RIVER.
HOWEVER...STREAMFLOWS ON THE MAINSTEM SNAKE RIVER BELOW AMERICAN
FALLS...AND IN MOST SUB BASINS OF THE SNAKE RIVER IN SOUTHERN IDAHO
WERE BELOW OR MUCH BELOW NORMAL...INCLUDING THE WOOD AND LOST RIVER
BASINS...PORTNEUF AND BRUNEAU BASINS. IN SOUTHEAST OREGON...
STREAMFLOWS WERE BELOW OR MUCH BELOW NORMAL.
