The Honna River runs roughly north to south through gently rolling terrain on Graham Island, Haida Gwaii, BC. The Honna Community Watershed is ~52 square kilometers and is the drinking water supply for the Village of Queen Charlotte. Resource roads affect water quality in the Honna River, primarily through inputs of road sediments, which can be hazardous to aquatic habitats and create complications for downstream water treatment. Please see below for a list of publications related to this project.
