Stream Rehabilitation Using LOD Placements and Off-channel Pool Development

Microform - 1991

On the Queen Charlotte Islands, mass wasting triggered by either logging or natural events is the dominant geomorphic process acting to erode unstable terrain. Studies from 1982-84 identified several options for rehabilitating the characteristically steep streams that drain much of the active logging area in the Islands. This study began in May 1986 to further develop and test aspects of log placement strategies and to apply engineering principles in the design and construction of the structures. The rehabilitation sites were identified during a reconnaissance and then subjected to an extensive pre-construction evaluation in spring 1986. This was followed by construction during summer 1986 and the first of two post-construction evaluations, including an engineering assessment and a geomorphic evaluation. The final post-construction evaluation took place one year later, in August 1987. A total of 20 large organic debris (LOD) placement sites were constructed, with Macmillan Creek selected as the principal study stream.
