 Description

Kvichak Bay is located at the head of the much larger Bristol Bay and encompasses lands from Etolin Point near Nushagak Bay east and south to about 35 km south of the village of Knickknack (Cape Chichagof). The bay is fed by the Kvichak and Naknek rivers and several other smaller drainages. About 530 km2 of intertidal habitat fringes the bay, mostly unvegetated mud flats and sand flats. Areas especially attractive to shorebirds in autumn occur south of Knickknack off Johnston Hill; from Nakneck north to Libbyville: throughout Halfmoon Bay; and along the western shore from Lake Point to Etolin Point near Nushagak Bay. At low tide extensive interdial habitat is exposed throught upper Kvichak Bay, but its use by shorebirds has never been documented.

Kvichak Bay is an important as a stop-over/staging area for waterfowl, supporting close to 200,000 King Eiders and high numbers of black Scoters in the spring and fall. It is also a part of an ecological system which supports a multi-million dollar salmon fishing industry.

Information from limited assessments shows that Kvichak Bay is used by Black-bellied Plovers, Pacific Golden Plover, Greater Yellowlegs, and Dunlin. Studies in nearby areas suggest that dominate species would also include: Western Sandpiper, Long-billed Dowitcher, Short-billed Dowitcher, Rock Sandpiper, and Bar-tailed Godwit.


The combined lagoon and by system along the southern shore of Bristol Bay support hundreds of thousands of individual shorebirds and high proportions of several flyway populations of shorebirds. Shorebirds that use these habitats migrate south to spend the winter along Pacific coast of the Americas or cross the Pacific Ocean to Australia, New Zealand, Southeaster Asia, and Oceania. Dominant species include the Dunlin, Wester Sandpiper, Long-billed Dowitcher, Short-billed Dowitcher, Rock Sandpiper, and Bar-tailed Godwit. The entire population of the Beringian Marbled Godwit stages in these bays, and this subspecies of Marbled Godwit breeds exclusively on the norther Alaskan Peninsula. For species that migrate directly across the ocean to Hawaii or other South Pacific islands (e.g., Pacific Golden-Plover, Bar tailed Godwit, Ruddy Turnstone), Bristol Bay lagoons provide the last stopover before undertaking long overwater flights. Dunlins, dowitcher, and possibly Western Sandpipers also use the Peninsula?s lagoons to replenish energy reserves before departing for non-stop flights across the Gulf of Alaska.
