Streamflow values across the area are at near normal levels for
this time of year. Ground water levels are also in the normal
range. Upstream reservoir levels are near to above normal for the
time of year as are area soil moisture conditions.

During the next seven days, there are small chances for showers
today and again early next week but the weekend is expected to be
dry. The result will be near to below normal rainfall over the
area during the week. The outlook from the Climate Prediction
Center for the rest of March shows above normal rainfall while the
outlook for March through May indicates near normal rainfall.

In consideration of the above factors, this outlook calls for an
above normal risk of flooding through April.

If needed, the next Winter/Spring Flood Outlook will be issued by
April 4th.
