Bristol Bay Watershed Assessment: What we're studying and why

We're conducting a scientific assessment to understand how large-scale development would affect water quality and habitat in the Bristol Bay watershed - the habitat of one of the largest salmon populations in the world. Though the Bristol Bay watershed is composed of nine major rivers, we're focusing primarily on the Kvichak and Nushagak river drainages.
