American Falls was a landmark waterfall on theSnake River, named after a party of American trappers whose boat went over the falls. TheWilson Price Hunt expedition in 1811 camped at the falls one night and the expedition ofJohn C. Frémont was here in 1843. TheOregon Trail passed north of town, through the present-day reservoir. Power plants first sprang up at the falls in 1901. American Falls was the first town in the U.S. to be entirely relocated.[5] It was moved in 1925 to facilitate construction of the nearbyAmerican Falls Dam. The old townsite sits at the bottom of the reservoir, northwest of the present city. A larger dam was completed in 1978, downstream from the deteriorating 1927 structure, which was later demolished.[6]
According to theUnited States Census Bureau, the city has a total area of 1.69 square miles (4.38 km2), all of it land.[7]
