Boulder Mountain, East Side Professional Review and Guide
"Located approximately 200 miles southeast of Salt Lake City and 300 miles northeast of Las Vegas, Boulder Mountain (the Boulders) was until just recently among Utah’s best-kept fishing secrets. The 80-some-odd fishable lakes and reservoirs, some connected by small, fast-running streams, are similar in appearance to still waters in the Uintas, but the fish are larger.
Types of Fish: Brookies, rainbows, cutthroats, and sterile hybrids: splake, tiger trout, and brake (male brown–female lake). This eTrail covers the "where, when, and how" to fish in this region. You'll get a full-page map and information on the known hatches, suggested equipment to bring, and the best flies to use."
