Rainbow Trout
Rainbow trout fishing around Denver offers diverse opportunities, from freestone streams to stocked reservoirs. The South Platte River, particularly sections below dams, is a renowned tailwater fishery. Spring and fall provide the most consistent action, with hatches triggering feeding frenzies. For rivers, nymphing with small patterns like pheasant tails and hare's ears is productive, especially during the colder months. In reservoirs like Dillon or Gross, try trolling spoons or spinners, or casting streamers from shore. A key to success is matching the hatch; observe what insects are present and select your flies accordingly. Access to some prime fishing spots requires a bit of hiking, but the reward of wild rainbows in pristine settings is well worth the effort. Remember to check current regulations, as some areas have catch-and-release restrictions or specific gear requirements.
