DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE CARIBOU ME
218 AM EDT SAT SEP 18 2021

.SYNOPSIS AND DROUGHT INTENSITY...
DROUGHT CONDITIONS HAVE IMPROVED DURING THE PAST TWO WEEKS ACROSS
PORTIONS OF NORTHERN AND EASTERN MAINE. PLEASE VISIT THE U.S. 
DROUGHT MONITOR AT WWW.DROUGHTMONITOR.UNL.EDU FOR A VISUAL 
DEPICTION OF THE DROUGHT CONDITIONS ACROSS THE STATE. 

DURING THE PAST 14 DAYS (SEPTEMBER 3-16) PRECIPITATION HAS BEEN 
ABOVE TO WELL ABOVE NORMAL ACROSS MOST OF THE REGION AND HAS 
RANGED FROM 150 TO 300 PERCENT OF NORMAL. THE ONLY EXCEPTIONS ARE 
ACROSS SOUTHEAST WASHINGTON COUNTY WHERE PRECIPITATION RANGED 
FROM 50 TO 100 PERCENT OF NORMAL, AND ACROSS NORTHERN SOMERSET 
COUNTY WHERE PRECIPITATION RANGED FROM 125 TO 150 PERCENT OF 
NORMAL. DUE TO THE NATURE OF SHOWERS AND THUNDERSTORMS, SOME LOCAL
BASINS RECEIVED MORE OR LESS PRECIPITATION THAN DESCRIBED ABOVE. 

.PRECIPITATION...
PRECIPITATION FOR THE MONTH OF JULY RANGED FROM 150 TO 300 
PERCENT OF NORMAL DOWNEAST, NEAR NORMAL ACROSS MOST OF CENTRAL 
MAINE, AND FROM 25 TO 75 PERCENT OF NORMAL ACROSS FAR NORTHERN 
MAINE TO THE NORTH OF THE KATAHDIN REGION. 

PRECIPITATION FOR THE MONTH OF AUGUST RANGED FROM 100 TO 130 
PERCENT OF NORMAL ALONG THE DOWNEAST COAST AS WELL AS ACROSS 
SOUTHEAST AROOSTOOK COUNTY. ELSEWHERE, PRECIPITATION WAS BELOW 
AVERAGE AND RANGED FROM 30 TO 70 PERCENT OF NORMAL. AGAIN, DUE TO 
THE NATURE OF SHOWERS AND THUNDERSTORMS, SOME LOCAL BASINS 
RECEIVED MORE OR LESS PRECIPITATION THAN DESCRIBED ABOVE. 

DURING THE PAST 90 DAYS, PRECIPITATION HAS RANGED FROM 130 TO 200
PERCENT OF NORMAL DOWNEAST AND INTO NORTHERN WASHINGTON COUNTY, 
AND FROM 50 TO 90 PERCENT ACROSS THE REMAINDER OF NORTHERN MAINE.
THERE IS A SMALL AREA IN BETWEEN WITH NEAR NORMAL PRECIPITATION
THAT EXTENDS FROM SOUTHERN PISCATQUIS COUNTY NORTHEAST TO NEAR
PRESQUE ISLE IN AROOSTOOK COUNTY. 

.HYDROLOGIC CONDITIONS...
RIVER FLOWS: HAVE IMPROVED SIGNIFICANTLY OVER THE PAST 2 WEEKS. 
FLOWS RANGE FROM 161 TO 232 PERCENT OF NORMAL ON THE SAINT JOHN 
RIVER, 93 TO 116 PERCENT OF NORMAL ON THE AROOSTOOK RIVER, AND 115
TO 129 ON THE PENOBSCOT RIVER. ON THE PISCATAQUIS RIVER FLOWS
RANGE FROM 63 TO 77 PERCENT OF NORMAL. THE LOWEST FLOWS RELATIVE
TO NORMAL ARE CURRENTLY ON THE FISH RIVER AT FORT KENT AT 28
PERCENT OF NORMAL. 

SEVEN TO 14 DAY STREAMFLOWS HAVE IMPROVED SIGNIFICANTLY OVER THE
PAST 2 WEEKS AND ARE NOW RATED AS NORMAL TO MUCH ABOVE NORMAL 
ACROSS ALL OF NORTHERN AND EASTERN MAINE. 

EVAPORATION AT CARIBOU SO FAR THIS SEPTEMBER (THROUGH SEPTEMBER 
17TH) HAS BEEN 1.32", WHILE 3.74" OF RAIN HAS BEEN OBSERVED. 

GROUNDWATER AND WATER STORAGE (LAKES/RESERVOIRS): A LONG-TERM 
IMPACT OF THE DROUGHT IS LOWER GROUNDWATER LEVELS. GROUNDWATER 
LEVELS ARE VERY SLOW TO RESPOND, AND ALSO CAN BE VERY SLOW TO 
RECOVER. SOME WELLS HAVE SHOWN APPARENT IMPROVEMENT, WHICH IS DUE
TO THE FACT THAT SEPTEMBER TYPICALLY HAS LOWER GROUNDWATER LEVELS
CONDITIONS THAN AUGUST. THIS IMPROVEMENT IN DROUGHT IMPACTED 
AREAS IS NOT DUE TO RECHARGE, WHICH HAS BEEN SLOW TO RESPOND TO 
RECENT RAIN. MONITORING WELLS IN MAINE SHOW NORMAL CONDITIONS 
ALONG THE I-95 CORRIDOR INTO EASTERN MAINE, WITH WELLS WEST OF 
I-95 AS WELL AS ACROSS FAR NORTHERN MAINE SHOWING BELOW NORMAL 
CONDITIONS. 

.SUMMARY OF IMPACTS...
WATER RESOURCES: NONE AT THIS TIME. THERE HAVE BEEN SOME REPORTS
OF PRIVATE WELLS THAT HAVE RUN DRY IN AROOSTOOK AND PENOBSCOT
COUNTIES, BUT THE LOCATION OF THESE WELLS IS UNKNOWN. WE ARE NOT 
AWARE OF ANY COMMUNITY WATER RESTRICTIONS IN OUR REGION AT THIS 
TIME.

WILDFIRE CONDITIONS: THE MAINE FOREST SERVICE HAS REPORTED 612
WILDFIRES IN MAINE THIS YEAR AS OF SEPTEMBER 9TH, BUT ONLY 10 OF
THOSE FIRES HAVE BEEN OBSERVED DURING THE PAST TWO WEEKS. RECENT
RAINS HAVE RAISED OUR FUEL MOISTURE WHICH HAS MITIGATED THE FIRE
DANGER ACROSS NORTHERN AND EASTERN MAINE. 

AGRICULTURAL CONDITIONS: GIVEN THE RECENT RAINS, PRODUCERS ARE
REPORTING EXCELLENT CROP GROWTH AND QUALITY IN AREAS WHERE DROUGHT
CONDITIONS HAVE DIMINISHED. MANY CROPS WILL BE HARVESTED DURING
THE NEXT 1 TO 2 WEEKS IN THE AGRICULTURAL AREAS OF AROOSTOOK 
COUNTY. 

.DROUGHT MITIGATION ACTIONS...
THE STATE OF MAINE HAS ACTIVATED ITS DROUGHT TASK FORCE. HYDRO 
OPERATORS ARE MONITORING CONDITIONS AND BALANCING NEEDS OF LAKE 
LEVELS, HYDROELECTRIC POWER GENERATION NEEDS, AND DISCHARGES TO 
MAINTAIN STREAM FLOW AND RECREATION NEEDS DOWNSTREAM. 

IN RESPONSE TO ESCALATED DROUGHT, THE MAINE EMERGENCY MANAGEMENT
AGENCY HAS PUBLISHED AN ONLINE SURVEY FOR HOME OWNERS TO REPORT 
PRIVATE WELLS RUNNING DRY AND OPPORTUNITIES FOR ASSISTANCE:
HTTPS://MAINE-DRY-WELL-SURVEY-MAINE.HUB.ARCGIS.COM/.

.PRECIPITATION/TEMPERATURE AND HYDROLOGIC OUTLOOKS...
THE CLIMATE PREDICTION CENTERS OUTLOOK FROM DAYS 6 TO 10 (SEP 
23-27) FAVORS ABOVE AVERAGE TEMPERATURES ACROSS THE REGION. THE 
PRECIPITATION OUTLOOK CALLS FOR INCREASED CHANCES OF ABOVE
AVERAGE PRECIPITATION. THE DAYS 8-14 (SEP 25-OCT 1) CALLS FOR AN 
INCREASED CHANCE OF ABOVE AVERAGE TEMPERATURES. THE ODDS ARE 
SLIGHTLY TILTED TOWARD ABOVE AVERAGE PRECIPITATION.

.NEXT ISSUANCE DATE...
THIS PRODUCT WILL BE UPDATED BY OCTOBER 7, 2021.
