Tips for Anglers

Timing is Key

Keep a close eye on water temperatures and river conditions, as the timing of the salmon fly hatch can vary from year to year. Generally, early June marks the peak of the hatch, but fluctuations in weather and water levels can influence insect activity.

Match the Hatch

When selecting flies, opt for patterns that closely resemble the size and coloration of the salmon flies. Large dry flies and nymphs in shades of orange and black are typically effective during the hatch, enticing trout to rise to the surface in pursuit of their insect prey.

Explore Off the Beaten Path

While popular stretches of river can offer productive fishing during the salmon fly hatch, don’t overlook lesser-known tributaries and backcountry streams. These hidden gems often harbor trophy trout and provide a more intimate angling experience away from the crowds. A great resource to find these locations is the Colorado Parks & Wildlife’s Fishing Atlas.
