Thunder Bay River Streambank Restoration
Thunder Bay River Watershed,
Thunder Bay River Watershed Council
Basin Program Funds:
Sediment currently introduced by erosion from river banks, shorelines and
road/stream crossing has had serious and growing negative impact on water
quality. This is apparent in the gradual, but documentable, decline in quality
fisheries habitat throughout the Thunder Bay river system.
The purpose of the Thunder Bay River Streambank Restoration project is to
install streambank erosion control demonstration sites at selected locations
along the Thunder Bay River to serve as a catalyst for future stabilization
Five sites with high visibility to the community will be chosen
to demonstrate the effective use of stabilization techniques to prevent further
soil erosion. An information/education component of the project will publicize
the results of the demonstration projects through various vehicles such as
newspaper articles, the Thunder Bay Watershed Council newsletter and television.
The Great Lakes Basin Program is spending $10,000 over a 12 month
period to support the installation of 5 streambank erosion control measures.
Seven streambank sites totaling 2,380 lineal feet have been rehabilitated using
various techniques such as rock rip-rap, toe stabilization with tree revetment,
and bank seeding with jute netting. Approximately 125 cubic yards per year of
sand have been prevented from eroding at these restored sites. One of the demonstration
sites has been publicized through the Thunder Bay Watershed Council's newsletter
(distribution of 200), the Huron Pines RC&D newsletter (distribution of 250),
the Alpena local newspaper (distribution of 12,000) and at a NRCS meeting in
which 250 people were in attendance. This site demonstrates the use of whole
tree revetment anchoring method, seeding, hay mulch and jute netting. This technology
has been transferred to an engineering firm doing similar restoration at the
Air National Guard base in Alpena.
As a result of this project, the Thunder Bay Watershed Council
has collaborated with the Federal Energy Relicensing Commission (FERC) in
developing actual restoration scenarios and cost estimation for restoration
associated with hydroelectric generation.
