What is "bristol bay"

Bristol Bay (Iilgayaq in Central Yup'ik) is the eastern-most arm of the Bering Sea, at 57° to 59° North 157° to 162° West in Southwest Alaska. Bristol Bay is 400 km (250 mi) long and 290 km, (180 mi) wide at its mouth. A number of rivers flow into the bay, including the Cinder, Egegik, Igushik, Kvichak, Meshik, Nushagak, Naknek, Togiak, and Ugashik.

Upper reaches of Bristol Bay experience some of the highest tides in the world. One such reach, the Nushagak Bay near Dillingham and another near Naknek in Kvichak Bay have tidal extremes in excess of 10 m (30 ft), ranking them — and the area — as eighth highest in the world. This, coupled with the extreme number of shoals, sandbars and shallows, makes navigation troublesome, especially during the area's frequently strong winds. As the shallowest part of the Bering Sea, Bristol Bay is one of the most dangerous areas for large vessels.
