19th century
Eagle Island in Idaho was settled in 1863 by Truman Coe Catlin, who later shifted from crop farming to dairy farming, starting the island's dairy tradition. He also pioneered irrigation in the area by constructing a wide irrigation ditch. The most notable early community developer was Thomas Hugh Aiken, a Canadian surveyor, who helped establish the Eagle community in the 1870s. Despite the construction of Arrowrock Dam in 1915 and subsequent dams, flooding has been a recurrent issue for residents, leading to continued efforts to mitigate flood risks.

20th century
The Eagle Fish Hatchery, established in the late 1940s in Idaho, was originally part of a trout program until the 1980s. In 1991, it was restructured to support the conservation of Snake River sockeye salmon, an endangered species listed that year. The hatchery's mission shifted to preserving the species and its genetic diversity through the development of eight broodstocks derived from smolts, anadromous adults, and residual populations. It also houses the IDFG Eagle Fish Health Laboratory.
