Overview
The Springfield Bottoms and American Falls Reservoir WHSRN site surrounds the American Falls Reservoir in South-east Idaho. This site of regional importance consists of emergent mudflats with invading willows and annual cockleburn crops. 50,000-80,000 shorebirds use the site, thirty species in total. The area is also 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. The reservoir holds 1.7 million acre-feet of water, which is emptied almost on an annual basis.
