Wary, predatory and nocturnal by preference. The big ones eat streamers. Pre-spawn aggression: this is streamer season for the fish of the year.

About this water

6,000 shallow acres at 6,470 ft, Fremont County, ID. The trophy stillwater of Island Park.

Fishing Henrys Lake: the full guide

The shallow giant factory

Henrys spreads shallow and absurdly fertile at 6,470 feet: scud and leech soup growing cutthroat, brook trout and the famous cutbow hybrids at rates that make 20-inch fish ordinary and 10-pounders annual. It may be America's best public stillwater for a legitimate trophy on flies: and it looks like a puddle doing it.

Stillwater craft

The lake fishes like a giant spring creek: strip leeches and scuds along the weed channels, hang chironomids at the springs, and watch for the cruising wakes that mean hybrids hunting. Classic beats: the State Park flats, Staley's Springs' cold seams, the Cliffs' drop: all worked from tubes and small boats at dawn before the wind.

Brookies of consequence

Henrys grows the country's biggest public-water brook trout: 3-5-lb fish with 7s possible: fall's spawn colors turn them into paintings. October's pre-ice weeks concentrate them at the springs and creek mouths: the lake's most beautiful fishing in its most brutal weather.

Rules of the bowl

The season opens late May and closes with ice (check IDFG dates); limits protect the hybrids; and afternoon wind is a scheduled event: fish 6-11 AM, respect the whitecaps. Island Park's services sit minutes away: pair Henrys with the Henrys Fork and Yellowstone's west side for the region's grand slam.

Common questions

How big do Henrys Lake trout run?

Averages start at 18 inches: hybrids past 10 lb come every season. It is trophy water by design: heavy tippet and big nets are standard.

When does Henrys Lake fish best?

Opener weeks (late May-June) and October's cold finale: mornings always. The wind owns afternoons: plan around it like the locals.
