DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE CARIBOU ME
518 PM EDT THU SEP 30 2021

.SYNOPSIS AND DROUGHT INTENSITY...
DROUGHT CONDITIONS HAVE IMPROVED SIGNIFICANTLY DURING THE PAST 
WEEK ACROSS MOST OF NORTHERN AND EASTERN MAINE. THIS WAS DUE TO 
BACK-TO-BACK RAINFALL EVENTS DURING THE WEEKEND OF SEPTEMBER 
25TH-26TH THAT PRODUCED WIDESPREAD RAINFALL OF 1 TO 3 INCHES 
ACROSS THE REGION WITH LOCAL AMOUNTS IN EXCESS OF 4 INCHES. 

THE ONLY AREAS WHERE MODERATE DROUGHT (D1) REMAIN ARE ACROSS 
NORTHERN SOMERSET COUNTY, A SMALL PORTION OF NORTHWEST 
PISCATAQUIS COUNTY, AND A VERY SMALL PORTION OF WESTERN AROOSTOOK 
COUNTY. 

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 15-28) PRECIPITATION HAS BEEN
WELL ABOVE NORMAL ACROSS MOST OF THE REGION AND HAS RANGED FROM 
150 TO 300 PERCENT OF NORMAL. THE ONLY EXCEPTIONS WERE A SMALL 
AREA ALONG THE WASHINGTON AND HANCOCK COUNTY BORDER WHERE 
PRECIPITATION RANGED FROM 90 TO 130 PERCENT OF NORMAL, AND ACROSS 
NORTHERN SOMERSET COUNTY WHERE PRECIPITATION RANGED FROM 100 TO 
130 PERCENT OF NORMAL. 

.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 150 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 WEEK. 
FLOWS RANGE FROM 73 TO 92 PERCENT OF NORMAL ON THE SAINT JOHN 
RIVER, 337 TO 342 PERCENT OF NORMAL ON THE AROOSTOOK RIVER, AND 
278 TO 296 ON THE PENOBSCOT RIVER. ON THE PISCATAQUIS RIVER FLOWS
RANGE FROM 147 TO 299 PERCENT OF NORMAL. THE MATTAWAMKEAG AT
MATTAWAMKEAG IS AT AN AMAZING 1216 PERCENT OF NORMAL FOR SEPTEMBER
30TH.

SEVEN TO 14 DAY STREAMFLOWS HAVE IMPROVED SIGNIFICANTLY OVER THE
PAST WEEK AND ARE NOW NORMAL ACROSS MUCH OF THE CROWN OF MAINE, 
AND ABOVE TO WELL ABOVE AVERAGE ACROSS THE REMAINDER OF NORTHERN 
AND EASTERN MAINE.

EVAPORATION AT CARIBOU SO FAR THIS SEPTEMBER (THROUGH SEPTEMBER 
29TH) HAS BEEN 2.28", WHILE 6.13" OF RAIN HAS BEEN OBSERVED. SOIL 
MOISTURE LEVELS SHOWED SOME IMPROVEMENT ACROSS THE REGION WHEN 
VIEWED OVER THE LAST 7 DAYS, AND DURING THE MONTH OF SEPTEMBER. 
THE EVAPORATIVE STRESS HAS DROPPED SIGNIFICANTLY SINCE AUGUST WITH
COOLER AND MORE SEASONABLE TEMPERATURES RETURNING.

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. MOST CROPS HAVE BEEN 
HARVESTED AT THIS POINT, AND THE AGRICULTURAL DEMAND FOR WATER 
HAS GREATLY BEEN REDUCED. 

.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 (OCT 
6-10) FAVORS ABOVE AVERAGE TEMPERATURES ACROSS THE REGION. THE 
PRECIPITATION OUTLOOK CALLS FOR INCREASED CHANCES OF BELOW 
AVERAGE PRECIPITATION. THE DAYS 8-14 (OCT 8-OCT 14) OUTLOOK CALLS
FOR AN INCREASED CHANCE OF ABOVE AVERAGE TEMPERATURES. THE ODDS 
ARE SLIGHTLY TILTED TOWARD BELOW AVERAGE PRECIPITATION. 

IT IS LIKELY THAT THERE WILL NOT BE ANY SIGNIFICANT CHANGES TO 
THE AREAS THAT ARE STILL IN MODERATE DROUGHT DURING THE NEXT 
WEEK. STREAMS AND RIVERS WILL LIKELY SEE A GRADUAL FALL DURING THE
NEXT WEEK. 

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