The streams that flow from Boulder Mountain are rocky and and shaded by high sandstone cliffs and trees throughout their winding course. There are sections with deep pools below piles of huge boulders that flow out into long riffles before cascading over more big boulders and forming yet another deep pool. This is how it is all day while fishing these streams. Around every bend in the stream is another breathtaking sight. The pink sandstone cliffs that loom over the stream form a picture perfect backdrop to every pool you encounter.
The image at right shows one of the deep runs than are formed where sandstone meets stream. These sandstone cliffs are always undercut and are perfect habitat for big browns that love to hold in such places. After you work a deeper run like this over with a dryfly, it's time to run a weighted nymph along the bottom near the undercut cliff. This usually results in hooking the biggest trout in the hole before you move up.
A short distance upstream you try your luck at the fast riffle where it enters the deep pool. This previously undisturbed area will usually end up yielding a couple more nice trout before you move on. The streams of Boulder Mountain are some of the finest flyfishing streams in Utah. Most anglers have never realized that there are great trout streams in this part of the state. Rarely fished, these streams are as close to pristine as that overly used term could possibly describe.
