Ugashik bay is a large S- shaped estuary fed by three major drainages, the King Salmon, Dog Salmon and Ugashik Rivers, the latter originating from Ugashik Lakes. Extensive intertidal flats (72 km) occur along the west and east sides of the bay, while intertidal sedge meadows, lakes, and ponds occur at the head of the bay, especially along the peninsula south of the village Pilot Point. Most of ugashik Bay is within the boundaries of the Ugashik Bay State Critical Habitat Area.

Ornithological Summary

Ugashik Bay is an important waterfowl staging area, particularly geese. More than 1% of Emperor goose population occurs there during spring and autumn migration (Sedinger and Bollinger, 1987; Gill et al. 1997; Dau 1982). Area important for waterfowl includes 5-10 km-wide offshore area as well.
Observations of shorebirds at Ugashik Bay come from several sources, mostly autumn waterfowl staging studies. (see references above). Twenty species of shorebirds have been recorded from the area; 8 regularly breed in the area and 12 commonly use it in late summer and autumn. Important spring and autumn records include several thousand and close to 20,000 shorebirds respectively (WHSRN profiles). The most noteworthy shorebird species in the area are Dunlins, Marbled and Bar-tailed Godwits, Greater Yellowlegs.

Total shorebirds: spr/aut; 1000s to 20,000; A4iii.
