Boulder Mountain

Image of Boulder Mountain

Location: The area loosely referred to as the Boulder Mountain is located in Wayne and Garfield counties and includes Boulder Mountain, the Aquarius Plateau, Griffin Top and Escalante Mountain. It is roughly bounded and accessed by Highway 24 on the north, Highway 12 to the east and south and Forest Road 154 to the west.

There are approximately 80 fishable lakes or ponds in the area. There are several Forest Service campgrounds at the major access points. Some of the best fishing at these lakes occurs in fall. Types of fish: The Boulder Mountain is best known for its brook trout. Lakes on the mountain also contain rainbow trout, cutthroat trout, tiger trout, splake, and grayling.

How to fish: A popular technique is fishing a black marabou jig with spinning gear. A long rod will enable you to jig the lure near cover (vegetation, logs, etc). Flyfishers will generally do best using a sinking fly such as a wooly bugger, leech or scud pattern. The old reliable worm will also work. Special regulations apply to some of the lakes so check the proclamation. These are high elevation lakes so be prepared for any changes in weather.

Latest fishing report

Some of the Boulder Mountain lakes closed to fishing on November 1. Make sure you read the Utah Utah Fishing Guidebook before you go to see which lakes are closed. Note: The lakes are listed under individual names, and not Boulder Mountain Lakes.

Expect snow and the possibility of difficult access after recent storms. Fall provides some of the best fishing of the year on Boulder Mountain. The cooling weather triggers fish to feed actively to add extra weight before winter. Fall-spawning species — like brook, tiger and splake trout — also go through pre- and post-spawn aggression that can lead to great fishing success. Continue using your preferred techniques, but look for actively cruising fish near shore. Spin anglers should try marabou jigs, tube jigs, Gulp minnows, spinners, Jake's or Kastmasters. Bait anglers should focus on natural baits like nightcrawlers. Cut bait and frozen minnows are especially effective for predatory tigers and splake — unless they are in spawning mode. Fly anglers should bring an assortment of streamers, terrestrials and bead head nymphs along with your favorite dry patterns. Most of the Boulder lakes are full of freshwater shrimp, so scuds are a must in your fly box. Egg patterns are worth a try for the actively spawning fish that won't touch anything else.
