...MUCH WARMER TEMPERATURES TO INCREASE FLOODING POTENTIAL ON THE
PARK RIVER NEAR GRAFTON...

Warm temperatures are forecast over the Park River Basin starting
this weekend and persist. High temperatures are expected to be
well above freezing during this period with low temperatures near
or even above freezing.

Based on field observations and satellite imagery most of the snow
has melted in the downstream half of the basin. Even though the snow
has melted, little of that water has made it into the river. Field
reports indicate that there is a lot of ice remaining in the
field drains and ditches waiting to be released into the river
system. Most of the snow in the basin fell in December and has
experienced several warmups since then.

There is uncertainty regarding the timing of the release of the
water in the lower basin which is frozen in the drainage network.
Once the soil warms up and the ice melts, the water may run off
more rapidly. Ice jams are common at this location and can cause
rapid rises.

As river levels rise over the coming days, flood warnings and more
information should be expected for the Park River forecast points.

Those with interests along the Park River should be prepared for
rising river levels.
