Lake Como Fishing Guides
A mountain irrigation lake under the Como Peaks in the Bitterroot Range, close enough to Darby to fish in an evening and wild enough to feel remote.

About the Lake Como
Lake Como sits in a glacial basin on the east front of the Bitterroot Range west of Darby, held by a low dam that raised a natural lake into an irrigation storage reservoir for the Bitterroot valley below. The Como Peaks rise steeply behind it and Rock Creek enters at the head, running down out of the Selway Bitterroot Wilderness. The whole basin is Bitterroot National Forest land, which means the shoreline is public, developed with campgrounds and a trail that circles the water, and unusually accessible for a mountain lake of this character.
The gauge reports lake elevation, and as with any irrigation reservoir that number tells most of the story. The lake fills with snowmelt through late spring, holds near full through early summer, and is then drawn down through the irrigation season to serve the valley below. By late summer the surface can be well down, exposing a wide band of rocky shoreline and changing both the boat access and where fish hold. Anglers who check the elevation trace before driving up save themselves a wasted trip in a dry year.
The fishery is mixed salmonid water. Rainbow trout and westslope cutthroat are the mainstays, with brown and brook trout present, kokanee salmon in the open water and mountain whitefish throughout. Bull trout occur in the drainage and are protected, so identification matters here in a way it does not on most waters. Rock Creek above the lake offers small stream cutthroat fishing into the wilderness, and the Bitterroot River in the valley below is the larger draw for guided trips, which keeps pressure on the lake itself relatively modest outside high summer. The road in from the valley is short and paved most of the way, so this is one of the few mountain lakes in the Bitterroot that can be fished on an evening after work, and that accessibility is much of its appeal to anglers based in Hamilton and Darby.
