 Description

The reservoir holds 1.7 million acre-feet of water, which is emptied almost on an annual basis.  

The habitat consists of emergent mudflats with invading willows and annual cockleburn crops.  50,000-80,000 shorebirds use the site.  Thirty species in total.  

Springfield Bottoms and American Falls Reservoir is a major feeding area for white-ibis in summer and early fall and a major wintering area for ducks and geese in late fall to spring.  Many bald eagles hunt here as well.
