That stretch of the upper Provo is entirely public water. Its just like any small high mountain stream - find slower water in the pocketwater and they will eat any old attractor such as royal wulffs, Stimulator, elk hair caddis, etc... Most of the fish you catch will be brookies along with cutthroat and the oddball brown, rainbow and even grayling. My favorite stretch is from Provo River falls upstream to trial lake.
