American Falls Reservoir

American Falls Reservoir, at 56,000 acres, is the largest reservoir on the Snake River. Highway 39 rides the top of the reservoir’s 9-story-high dam for over half a mile and the lake can be seen stretching northeast as far as the horizon.

BIRDING: American Falls area is one of Idaho’s best year-round sites with the highest concentration of migratory shorebirds in the state.
