On September 1, 1999, the Shoreline Stabilization Project was installed by an
excavation contractor. The purpose of this demonstration project is to protect the
shoreline from further undercutting of the bank and to create shallow pools and hiding
zones for fish habitat. The details of this project design are described on this
website, and illustrations can be found as well.

on the south shore of the River, immediately offshore from the Zone 2 floodplain.
The location was changed to the other side of the River due to recent changes in
the flow dynamics at this location.
A
logger removed mature trees that were in danger of
falling into the River and kept their root wads intact. The trees were pruned of
their branches prior to installation.
After temporarily diverting the water away from the
project zone, the bank was
shaped to allow the placement of the tree trunks into the
shoreline.
The contractor anchored the
tree trunks into the shoreline, using permanent anchors
and cable.
Photo shows completed
installation, with root wads facing upstream. These
partially submerged roots will immediately provide places for juvenile fish to hide and
feed. Eventually, the dynamics of the River flow bouncing off of the tree trunk will
create shallow, quiet pools of water with gravel bottoms that will provide an excellent
spawning area.
