GMSWORKS-3 Peace River Side Channel Restoration - BC Hydro

een suggested, and lower values would apply to channels that require partial or limited
excavations.
Eleven sites (11) sites were short listed, predominantly consisting of closed side channels that
could be excavated into open flowing systems. In side channels above the Halfway River,
ongoing sedimentation and ice effects could be minimal and additional habitat complexing and
restoration works are suggested. Nine of the eleven sites (all except the lower 2 in the reach)
would benefit cold‐clear water fish assemblages including bull trout, rainbow trout and Arctic
grayling.
Side channel locations Site 23L and 32L were rated the highest of the assessed channel sites,
with site 32L selected as the best opportunity for implementation of side restoration objectives
in this study. Information and data gaps, and implementation issues have been provided in the
summary section, which will assist in guiding subsequent steps in the process of developing a
restoration plan for Site 32L. This study recommends ongoing coordination with other
GMSWORKS projects to better determine other factors that could influence the project or
scope.
