HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE BISMARCK ND
329 PM CST MON JAN 26 2015 /229 PM MST MON JAN 26 2015/

...ABNORMAL RUNOFF FROM RECENT RAINFALL...

RELATIVELY LIGHT RAINS...BETWEEN A FEW HUNDREDTHS OF AN INCH TO
NEAR ONE-HALF INCH OF WATER THAT FELL ACROSS THE SOUTHWESTERN
QUARTER OF THE STATE...HAS PRODUCED UNUSUALLY HIGH AMOUNTS OF
RUNOFF. SOME STREAMS THAT ARE FLOWING AT MUCH ABOVE NORMAL FOR
THIS TIME OF YEAR INCLUDE BUT ARE NOT LIMITED TO...THE KNIFE
RIVER...HEART RIVER...CANNONBALL RIVER...AND BEAVER CREEK NEAR
LINTON. WHILE NO REPORTS OF FLOODING HAVE BEEN RECEIVED...IT IS
POSSIBLE THAT UNSTABLE ICE WILL SHIFT AND CREATE EVEN HIGHER WATER
THIS WEEK.

NOT ONLY ARE SMALL RIVERS AND STREAMS RUNNING HIGH...BUT SEVERAL
RESERVOIRS ARE RISING IN RESPONSE TO INCREASED INFLOW. SHORELINE
CONDITIONS AS RESERVOIR AND RIVER LEVELS RISE WILL DETERIORATE AND
CAN POSE A SIGNIFICANT HAZARD FOR ACCESS. ANGLERS ARE URGED TO
CAREFULLY CHECK THE ICE BEFORE VENTURING OUT WITH A VEHICLE.
