Bristol Bay Borough was incorporated as the state's first borough in 1962. The borough functions as the official governing body for Naknek, South Naknek, and King Salmon and provides a variety of important services. The borough offices are located in Naknek.
The main feature of the borough's setting is the Naknek River and the cliffs bordering Kvichak Bay. At Naknek and South Naknek, where the cliffs are at their highest and the river is at its widest, the combination of the broad tidal river and the brown cliffs with their crowning greenery, present a truly striking picture. Looking across the river from one community to the other, the towns appear dwarfed by the cliffs on which they are situated.
