Water temperature is one of the most significant factors in the health of stream ecosystems. Temperature plays a critical role in salmonid reproduction and survivorship and is an essential indicator for monitoring the health of Bristol Bay salmon habitats, which support vital subsistence, commercial and sport fisheries. The objectives of this project are to develop an Implementation Strategy for a voluntary participation water temperature monitoring network for Bristol Bay; expand the annual Water Quality/QAPP Recertification training for local monitors to include standardized water temperature monitoring protocols; initiate temperature monitoring in select drainages; and seek long-term funding for a comprehensive regional monitoring program.
