Sixty-eight tributaries to the Bulkley River were examined by topographic maps and air photo interpretation to assess the degree and nature of the impacts on these streams by transportation and hydro-electric powerline corridors and agriculture/grazing/municipal land use. Of these 68, twenty-eight were recognized as having high to severe degree of impacts on high-value fish habitat. The remainder were of moderate to low-concern. The most significant source of impacts to these streams is identified as agricultural/rangeland and municipal land-use. An "impact corridor" through the length of the Bulkley River valley is identified. The management implications of these impacts are discussed and future work and research is recommended. Sampling of many of the streams to determine fish species present and distributions is the single most significant recommended action.
