Fishing report by Free Stone Fly Shop in Hamilton:
The East Fork is running clear and cool, offering excellent opportunities for both dry fly enthusiasts and nymph anglers. While this stretch of river fishes best during the early and late hours, the fish are responding well to terrestrials and attractor patterns throughout the day. The East Fork’s smaller, more intimate water makes for exciting sight-fishing, with cutthroat and rainbow trout eager to rise when a well-placed dry fly drifts past.
Current Conditions
- Flows: Moderate and steady, with good wading access across most of the river.
- Water Temperature: Starting in the low 60s during the early morning and warming to the mid-60s by afternoon—perfect for dry fly action before the midday slowdown.
- Weather: Warm, sunny days with light afternoon breezes. The cooler overnight temps are keeping mornings crisp and productive.
What’s Working
- Dry Flies: Hoppers (Morrish Hopper, Thunder Thighs, and Pink Chubby, sizes 8–12) and smaller attractor patterns like Purple Haze and Parachute Adams (sizes 14–16).
- Nymphs & Droppers: Frenchies, Pheasant Tail nymphs, and small Perdigons (sizes 14–18) are effective when fish aren’t looking up.
- Evening Bugs: Rusty Spinners and PMD patterns are producing during the last hour of light.
Guide Tips
- Fish the riffle corners, undercut banks, and softer inside seams where trout are holding and waiting for easy meals.
- Terrestrials are the ticket midday—don’t hesitate to twitch your hopper pattern for extra attention.
- The clear water calls for a delicate approach. Use longer leaders and light tippets to avoid spooking fish.
