How We Score Fishing Conditions
🌙 Lunar Phase
New and Full Moons produce peak fish activity (score: 2). First/Last Quarter and crescent phases produce moderate activity (score: 1–1.5).
💨 Barometric Pressure
Rising pressure (score: 2) strongly activates feeding. Stable pressure (score: 1) produces normal activity. Falling pressure (score: 0) suppresses the bite.
🌬️ Wind Speed
Light winds under 3 m/s (score: 2) are ideal. Moderate 3–8 m/s (score: 1). Strong winds above 8 m/s (score: 0.5–0) suppress feeding.
Frequently Asked Questions
What trout in Colorado?
Rainbow, brown, brook, and cutthroat trout are common. Species vary by elevation and location.
Best technique for Colorado?
Fly fishing dominates but spinners, soft plastics, and live bait all work. Adapt to insect hatches and water conditions.
What is the elevation issue?
High elevation (7,000+ ft) means cold water, thin air, and weather challenges. Water cools rapidly at altitude.
When is best to fish?
Summer (June-Sept) is peak. Spring is possible after snowmelt (May+). Fall is excellent. Winter is difficult.
Do I need special gear for high elevation?
Standard trout gear works but dress in layers. Weather changes rapidly. Carry rain gear and sun protection.
