HYDROLOGIC STATEMENT
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
815 PM CST MON FEB 9 2009
...ICE IN THE PLATTE...ELKHORN AND LOUP RIVERS IS SHOWING SIGNS
OF BREAKING UP...
AT 805 PM...EMERGENCY MANAGEMENT OFFICIALS REPORTED A VERY MINOR ICE
JAM IN ONE OF THE SECONDARY CHANNELS NEAR BIG ISLAND ALONG THE PLATTE
RIVER SOUTHWEST OF FREMONT. THIS IS A KNOWN AREA THAT FLOODS
FREQUENTLY DUE TO ICE ACTION...BUT NO HOMES OR ROADS APPEAR TO BE
THREATENED AT THIS TIME.
ALSO...RIVER LEVELS ALONG THE ELKHORN RIVER AT BOTH PILGER AND WEST
POINT APPEAR TO BE RISING ALSO. WHILE THE DETAILS ARE UNKNOWN AT
THIS TIME...IT IS POSSIBLE THAT AN ICE JAM MAY BE DEVELOPING OR HAS
ALREADY DEVELOPED DOWNSTREAM WHICH IS BACKING UP THE RIVER. THE
RIVER LEVEL COULD BE JUST BELOW FLOOD STAGE AT WEST POINT...AND IF
ADDITIONAL RISES OCCUR...SOME LOWLAND FLOODING MAY DEVELOP THROUGH
THE NIGHT.
EARLIER MONDAY AFTERNOON...PLATTE COUNTY EMERGENCY MANAGEMENT
REPORTED THAT FLOWS HAD INCREASED IN THE LOUP RIVER WEST OF GENOA.
THERE WAS SOME OPEN WATER...BUT A LOT OF ICE COVER WAS STILL IN PLACE
IN PLATTE COUNTY. EXPECT SOME BREAKUP OF ICE IN THE LOUP RIVER
THROUGH TUESDAY...WHICH COULD EVENTUALLY CAUSE SOME JAMS IN THIS
AREA.
IN THE PLATTE RIVER BORDERING PARTS OF DOUGLAS...SARPY AND
SAUNDERS COUNTIES...IT APPEARED THAT CHANNELS WERE OPENING UP
A LITTLE COMPARED TO THE PAST FEW DAYS. AN ICE JAM THAT HAD DEVELOPED
ON THE ELKHORN RIVER BETWEEN THE DODGE AND MAPLE STREET BRIDGES HAD
FLUSHED THROUGH AND LIKELY WAS MOVING DOWNSTREAM WITHOUT ADDITIONAL
INCIDENT.
AT HIGHWAY 64 WEST OF VALLEY...THE WEST CHANNEL WAS MORE OPEN
THAN IT WAS THURSDAY. THERE WAS STILL QUITE A BIT OF ICE COVER
IN PLACE...BUT THERE WAS SOME NON-FLOWING WATER ON TOP OF THE
ICE AND THE ICE DID NOT APPEARS TO BE QUITE AS THICK. CHANNELS
ALSO SEEMED TO BE OPENING UP FARTHER SOUTH ON THE
PLATTE...ESPECIALLY THE LOWER END.
IT APPEARS THAT THERE MAY BE ENOUGH ROOM IN THE RIVERS FOR
WATER LEVELS TO INCREASE...AND NOT CAUSE SIGNIFICANT FLOODING.
HOWEVER...RESIDENTS ALONG THE LOUP...THE PLATTE AND THE ELKHORN
RIVERS SHOULD BE AWARE THAT 1 TO 3 FOOT FLUCTUATIONS DUE TO
ICE ACTION OR LOCAL ICE JAMS MAY OCCUR THROUGH TUESDAY MORNING.
IF FLOODING DEVELOPS...SEEK HIGHER GROUND IMMEDIATELY.
