The Nahwitti River is one of the largest watersheds on Northern Vancouver Island, with a drainage area in excess of 225km2. Cave Creek is one of the tributaries within the Nahwitti watershed; these large tributaries provide valuable spawning and rearing habitat for several species of anadromous salmonids. Cave Creek is located in the upper portion of the Nahwitti River watershed and has been heavily impacted through human development and natural land slides (Figure 1 and Figure 2). The construction and subsequent failure of logging roads, coupled with natural slope failures, had resulted in large inputs of sediment into the Cave Creek system (photo 1). The sediment input had caused significant damage to fish habitat. Through the Nahwitti WBFSP process, the Cave Creek (referred to as Unnamed Tributary 8 in the WBFSP document) channel stabilization and rehabilitation was identified as a priority habitat restoration project (Gold and McCorquodale, 2003). Subsequent assessments of the drainage were conducted in 2004 and 2005, following a modified level I Fish Habitat Assessment Procedure. In the summer of 2005 restoration efforts were completed on the upper section of Cave Creek (Pepper and McCorquodale, 2006). In order to completely stabilize the channel further restoration works were completed on the lower channel in the summer of 2006.
