Goat
River South Channel Restoration - $18,750
The
end result of this project is to re-establish a controlled flow
to the south channel of the Goat River using an engineered structure
that will allow enough flow to sustain annual flow to benefit
fisheries and other ecosystem components, provide replenished
well water for residents currently experiencing seasonal well
drying, to help reduce flood and erosion on the main channel,
to provide a source of fire protection to south channel residents.
The project aims to provide a design for such a structure. The
south channel no longer receives flow and about 7km of productive
aquatic ecosystem has been lost. This loss of flow was due to
gravel aggradation blocking the head of the channel caused by
historic flood control activities and channel sculpting and
dyking. A controlled flow mechanism is required at the head
of the south channel in order to allow year round controlled
flow into the south channel without causing flooding and erosion
concerns thereby eliminating the need for bank armoring and
further aquatic ecosystem impacts related to flood control.
The
south channel is an important part of the Goat river aquatic
ecosystem. A fish habitat assessment conducted for the Goat
River has identified the south channel as a high priority assignment
for restoring fisheries to the Goat River, Kootenay River and
Kootenay Lake (Cope 2001 Fish and Fish Habitat Assessment for
the Lower Goat River, Creston, BC report prepared for the Columbia
Kootenay Fisheries Renewal Partnership). The structure will
be designed so that it does not take more water than historical
levels from the main channel-20-30% of main channel volume or
as agencies suggest.
The Goat River is regionally significant, historically one of
the main kokanee and the only known red listed Kootenay River
burbot spawning channel in the Canadian portion of the lower
Kootenay River.
