Installing geosynthetic clay liner under Corbin Flats wetland mitigation area.
completed design plans for the wetland mitigation projects and submitted
permit applications to the USAEC and all other agencies with
stream protection oversight. All agency permit authorizations were
received by the end of May, 2008 and materials for wetland construction
were ordered.
Construction at the Clancy Creek forested wetland restoration site
began in June of 2008. The diversion of Clancy Creek into the inactive
treed channel was easily accomplished using hand shovels to
create a new channel through a short distance of terrain contours.
The stream channel flow was initially split into the existing channel
and the reactivated channel for two months to provide fish spawning
habitat in the existing open meadow channel. In August, 2008,
the entire flow at the stream diversion point was directed into the
historic treed channel, and the valley area around the stream channel
was fenced to prevent cattle from grazing. In the autumn of
2008, fir and spruce trees were transplanted from areas of future
mine disturbance to more closely mimic the forest wetland that will
be disturbed during the mine expansion phase.
