An aquatic inventory was conducted in the Owen Creek Watershed from late June through mid-August 1998. These studies were a continuation of an aquatic inventory program initiated in 1996 in the Thautil and Owen Operating Areas (Morice TSA 20). The major focus of the study was to provide a broad-based aquatic inventory at an operational and landscape level to facilitate planning for forest development that minimizes impacts in the aquatic resources of the watershed. Emphasis was placed on accurately describing the distribution of fish within the study streams and establishing a riparian classification for all stream sections.
