About

Henrys Fork, Idaho — 1983 Wild and Scenic, Railroad Ranch. The Henry's Fork carries the name of Andrew Henry, a fur trapper and partner of William Henry Ashley who explored the upper Snake River drainage in 1824–1825 (Source: henrysfork.org). Half a century later, in 1880, the Oregon Short Line Railroad founded the Railroad Ranch, a 5,000-acre cattle operation that ran a herd of purebred Hereford cattle along the river's banks (Source: henrysfork.org). The waters they grazed beside drain a sprawling system — the watershed today encompasses 1.7 million acres and more than 3,000 miles of rivers, streams, and canals (Source: henrysfork.org). Recognition of that abundance came in stages. In 1983, Congress designated 64 miles of the Henry's Fork a National Wild and Scenic River (Source: wikipedia.org), and the following year a group of concerned citizens established the Henry's Fork Foundation in 1984 to debate the river's future, taking up riparian fencing projects and other improvements (Source: henrysfork.org). What began as trapping ground and cattle range now stands among the West's most carefully tended trout waters, its character guarded by the people who fish and farm it.
