Review of the Chilliwack River Watershed and
Forest Practices
In response to concerns
raised about BC Timber Sales Amendment 21 in the
Chilliwack River Valley, a study was conducted
to examine concerns about the effects of forest
operations on the flooding and channel stability
of the Chilliwack River.
The report evaluates the effects of past
and future forest operations and summarizes
causes and effects of flooding and landslide
hazards.
