Upper Owyhee River
Upstream from the reservoir, the Owyhee River and some of its tributaries make for fine fly casting.
One place that can be reached by four-wheel-drive vehicle is Three Forks, where the North, Middle and Main forks of the Owyhee River merge. Look for native redband trout and hybrids.
Otherwise, the best way to fish the river is to do so during a hiking or rafting trip. There’s nothing like getting a trout online in the wild!
