Black River (White Mountains)

Clear mountain stream flowing through boulders and pine forest, East Fork of the Black River, Arizona White Mountains.

The Black River, high in Arizona's White Mountains, is the kind of cold, clear, conifer-shaded freestone you don't expect to find in a desert state — and it's native-trout country at its heart.

About as good as it gets
River steady at a fishable height. On the feed top to bottom — start on the rises with a dry, drop a nymph if they stay down.

About this water

The Black River, high in Arizona's White Mountains, is the kind of cold, clear, conifer-shaded freestone you don't expect to find in a desert state — and it's native-trout country at its heart. The upper East and West Forks and the wilderness reaches run through Apache trout water, a story of careful recovery on a fish found nowhere else on earth, and that conservation context should set the tone for everything written about it: this is a place to fish gently and frame honestly, not a numbers river. Browns and rainbows are in the system too, and on the open, generally managed water it's lovely high-country fishing — attractors and a dropper through the runs and pools, a dry to a rising fish in the cool of the day. Much of the best water sits on the Fort Apache and San Carlos reservations and requires the tribe's own permit, separate from a state licence, so sort the permissions out first. It runs cold and bold on snowmelt, settles by midsummer, and fishes beautifully in the long mountain autumn.
