Although presenting a serious local problem where caving banks
are destroying or threatening cropland, bank erosion in the Repub-
lican River valley is not sufficiently widespread to warrant a
Federal bank stabilization program at this time. Many river bank
areas which were raw in 1951 are now covered and protected to some
degree by vegetation; and instances may be found where the concave
(eroding) side of a river bend has filled with an accretion of
sand which has grown up in willows. There are, however, areas of
active bank erosion which are aggravated by streamflow directed
against them by the islands and sandbars within the channel. At
several critical points, local interests have been successful in
checking the erosion by the strategic placement of light revetment,
such as old car bodies or anchored, felled trees, which have sub-
sequently induced sedimentation and vegetation. In laying out the
bank lines for any future improvement, advantage should be taken
of the protective cover already developed.
