ABOUT LEWIS LAKE IN
YELLOWSTONE NATIONAL PARK
Lewis Lake Fishing
Lewis Lake is one of the best stillwater fishing locations in the Jackson Hole region. Nestled in the Southeast corner of Yellowstone National Park, this natural lake is home to the Yellowstone Cutthroat trout and Lake trout. It is surrounded by large vistas, dense forests, and is only 45 minutes from the iconic Old Faithful Geyser. The combination of excellent fishing, stunning landscapes, and proximity to geothermal features makes Lewis Lake a unique fishing destination.
Part of what makes Lewis Lake so special is that it opens for fishing in late May on Memorial Day weekend. The lack of pressure from year-round anglers means the fishing could not be better. Some days it feels like we are reeling in a fish every cast! Lewis Lake is also great for those looking to keep the fish they catch and prepare it for dinner after a successful day on the water. This lake is the only body of water where we keep fish, due to its nonnative population of Lake trout.
When the river levels are rising from snowmelt, Lewis Lake is our go to. This beautiful backcountry lake is in the heart of the first national park and affords Teton views almost the entire drive to get there. Not only is it abundant in views and wildlife, the fishing – both fly fishing and spin fishing – is some of the best in the whole valley.
Fish Species
Anglers can expect to find:
- Lake Trout: The primary species in Lewis Lake, known for their size and fight.

Fishing Tips
- Best Spots: Focus on areas near the lake’s inlet and outlet, where water movement attracts fish.
- Fly Selection: Use flies that match the local hatches, and consider streamers and nymphs for deeper waters.
- Techniques: Both fly fishing and conventional methods are effective. Trolling can be particularly successful for lake trout.
