• Seasonal Patterns

  Averages move between 24°F in January and 65°F in July. Winter shuts things down for a spell, then spring reopens them fast. Ice-out usually falls in early April, and the weeks after it fish hardest. Going by climate averages, expect open water from about early April until roughly late November. September and October fish steadily right up to the freeze. At Iron Mountain Reservoir the season follows that pattern closely.

• Tackle & Baits

  Public sources are silent on who controls the bank. There is no mapped parking or launch nearby, which keeps numbers down. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Where a permit is needed, the nearest town usually sells it. Some stretches are reserved and marked as such on the ground. If the gate is shut, Canon Number 3 Reservoir at 2.1 miles is the nearest alternative.
