DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE BOISE IDAHO
1214 PM MDT FRI AUG 15 2014

...MODERATE TO EXTREME DROUGHT REMAINS ACROSS MUCH OF SOUTHERN IDAHO
AND SOUTHEAST OREGON...

SYNOPSIS...

MODERATE TO EXTREME DROUGHT CONDITIONS PERSIST ACROSS MUCH OF
SOUTHERN IDAHO AND SOUTHEAST OREGON. BELOW NORMAL SNOWPACK FOR THE
2013/2014 WINTER AND BELOW NORMAL SPRING RAINS SET THE STAGE FOR
INADEQUATE STORAGE IN MANY RESERVOIRS AND LOW STREAMFLOWS...ALLOWING
SHORT AND LONG-TERM DROUGHT IMPACTS TO PERSIST THROUGH THE HOT AND
DRY SUMMER MONTHS.

ACCORDING TO THE AUGUST 12 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...AND
ACROSS ACROSS SOUTH SIDE SNAKE RIVER BASINS...AND ACROSS MUCH OF THE
THE WEISER BASIN. EXTREME DROUGHT (D3 CLASSIFICATION) EXISTS ACROSS
PART OF THE MAGIC VALLEY IN SOUTH CENTRAL IDAHO. IN SOUTHEAST
OREGON...SEVERE TO EXTREME DROUGHT (D2 AND D3 CLASSIFICATION) EXISTS
ACROSS HARNEY AND MALHEUR COUNTIES...AND MOST OF BAKER COUNTY.

SUMMARY OF IMPACTS...

IN IDAHO...SURFACE IRRIGATION WATER SHORTAGES HAVE OCCURRED IN THE
WOOD AND LOST RIVER BASINS...AND ACROSS THE MAGIC VALLEY...AND SOUTH
SIDE SNAKE RIVER BASINS FROM SALMON FALLS CREEK WEST ACROSS THE
OWYHEE RIVER BASIN. IN MALHEUR COUNTY OREGON...MOST IRRIGATION
CANALS HAVE BEEN SHUT OFF...OR HAVE DWINDLED DOWN TO A TRICKLE AND
SOME CROPS WILL LIKELY BE LOST. OWYHEE IRRIGATION DISTRICT PLANNED
TO COMPLETELY SHUT OFF WATER TO CANALS ON AUGUST 15.

IN THE JUNIPER AREA OF NORTHERN MALHEUR COUNTY...LAND OWNERS ARE
SEEING SOME SPRINGS DRY UP WHICH IS CREATING A CHALLENGE FOR
LIVESTOCK WATERING. DROUGHT STRESSED VEGETATION FUELED A NUMBER OF
LARGE WILDFIRES IN SOUTHEAST OREGON IN JULY.

IMPACTS WILL EVOLVE AND CHANGE THROUGH THE SUMMER MONTHS. ADDITIONAL
IMPACT LIKELY INCLUDE LOW STREAMFLOW AFFECTING FISH AND WILDLIFE
HABITAT...REDUCED ACREAGE AND OVERALL PRODUCTION FOR SOME FIELD
CROPS...POOR RANGELAND CONDITIONS FOR CATTLE AND OTHER RANGE ANIMALS.

THE WILDLAND FIRE OUTLOOK FOR AUGUST INDICATES THAT THE POTENTIAL
FOR SIGNIFICANT FIRES IS ABOVE NORMAL ACROSS FAR SOUTHWEST IDAHO AND
SOUTHEAST OREGON...AND NORMAL ELSEWHERE IN IDAHO. THE OUTLOOK FOR
SEPTEMBER IS FOR CONDITIONS TO RETURN TO NORMAL.

STATE DROUGHT DECLARATIONS HAVE BEEN DECLARED FOR THE FOLLOWING
IDAHO COUNTIES...BUTTE...BLAINE...CLARK...CUSTER...AND LINCOLN.
OREGON STATE DROUGHT DECLARATIONS INCLUDE HARNEY AND MALHEUR
COUNTIES. BAKER COUNTY COMMISSIONERS HAVE SENT A REQUEST TO THE
OREGON GOVERNOR FOR A STATE DROUGHT DECLARATION. 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 AUGUST 13...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...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.

TEMPERATURES WERE GENERALLY NEAR NORMAL ACROSS SOUTH CENTRAL AND

REMAINDER OF IDAHO AND ACROSS SOUTHEAST OREGON.

PRECIPITATION AND TEMPERATURE OUTLOOK...

FOR THE REMAINDER OF AUGUST...NEAR NORMAL TEMPERATURES ARE FAVORED
FOR SOUTHEAST OREGON AND SOUTHWEST IDAHO...WITH BELOW NORMAL
TEMPERATURES FAVORED ELSEWHERE IN IDAHO. PROBABILITIES FAVOR ABOVE
NORMAL PRECIPITATION FOR NORTH AND NORTHEAST IDAHO...AND NEAR NORMAL
PRECIPITATION ELSEWHERE.

THE OUTLOOK FOR SEPTEMBER THROUGH NOVEMBER FAVORS ABOVE NORMAL
TEMPERATURES ACROSS THE REGION...BELOW NORMAL PRECIPITATION FOR THE
IDAHO PANHANDLE...AND NORMAL PRECIPITATION ELSEWHERE.

HYDROLOGIC SUMMARY...

OVER THE 30 DAY PERIOD FROM JULY 16 THROUGH AUGUST 14...
PRECIPITATION WAS ABOVE NORMAL ACROSS THE SOUTHERN HALF OF IDAHO AND
BELOW NORMAL FOR MOST OF NORTHERN IDAHO. AN ANOMALOUSLY WET STORM
SYSTEM IN EARLY AUGUST PRODUCED 2 TO 4 INCHES OF RAINFALL IN A 48
HOUR PERIOD OVER PORTIONS OF SOUTH CENTRAL IDAHO. IN SOUTHEAST
OREGON...PRECIPITATION WAS NORMAL TO ABOVE NORMAL IN EASTERN MALHEUR
COUNTY AND NEAR THE NEVADA BORDER...WITH BELOW NORMAL PRECIPITATION
ELSEWHERE.

USGS 28 DAY AVERAGE STREAMFLOWS AS OF AUGUST 14 WERE NORMAL FOR MOST
OF NORTHERN AND CENTRAL IDAHO...AND THE MAINSTEM SNAKE RIVER ABOVE
KING HILL...AND ON THE BEAR RIVER. HOWEVER...STREAMFLOWS FOR MANY OF
THE TRIBUTARY BASINS OF THE SNAKE RIVER WERE BELOW OR MUCH BELOW
NORMAL...INCLUDING THE WOOD AND LOST RIVER BASINS...THE PORTNEUF
BASIN...AS WELL AS SOUTH SIDE SNAKE RIVER BASINS. IN SOUTHEAST
OREGON...STREAMFLOWS WERE GENERALLY BELOW TO MUCH BELOW NORMAL.
