.RIVER AND RESERVOIR CONDITIONS...

RIVERS AND STREAMS IN THE REPUBLICAN RIVER BASIN ACROSS SOUTHWEST
NEBRASKA WERE RUNNING WELL BELOW NORMAL...GENERALLY RUNNING IN THE
5TH TO 24TH PERCENTILES. DUE TO INCREASES RAINFALL IN MAY...OTHER
PORTIONS OF WESTERN AND NORTH CENTRAL NEBRASKA HAVE SEEN INCREASES
IN STREAMFLOW. DURING MAY...MANY OF THE RIVERS AND STREAMS ARE NOW
RUNNING ABOVE AVERAGE IN THE 90TH PERCENTILE OR GREATER. RIVER
FLOODING OCCURRED IN MAY ALONG THE SOUTH PLATTE AND PLATTE RIVER
CHANNELS.

GROUNDWATER DEPTHS VARY ACROSS WESTERN AND NORTH CENTRAL NEBRASKA
FROM WELL BELOW NORMAL TO ABOVE NORMAL...HOWEVER THE MAJORITY OF THE
AREA IS SEEING NEAR OR BELOW NORMAL DEPTHS. LOCATIONS WITH THE
LOWEST READINGS ARE BEING MEASURED ACROSS THE REPUBLICAN RIVER BASIN
IN SOUTHWEST NEBRASKA WHERE SOME VALUES ARE LESS THAN THE 10TH
PERCENTILE.


.FIRE DANGER IMPACTS...

AS OF THE SECOND WEEK OF MAY...SPRING GREENUP HAS COMMENCED ACROSS
WESTERN AND NORTH CENTRAL NEBRASKA. GREENUP COMBINED WITH ABUNDANT
PRECIPITATION OVER THE PAST 3 WEEKS...HAS DECREASED FIRE DANGER
ACROSS WESTERN AND NORTH CENTRAL NEBRASKA.

BOTTOM LINE...RECENT MOISTURE HAS ALLEVIATED THE FIRE DANGER THREAT
FOR THE TIME BEING. HOWEVER...IF DRY CONDITIONS DO SUDDENLY SET
IN...ONE HOUR FUELS COULD CURE QUICKLY...LEADING TO AN INCREASED
THREAT FOR RANGE FIRES.
