Kootenai River
The Kootenai River (1 mile from Libby) is Libby’s home water and one of Montana’s premier trout fisheries. The turquoise river flows through town from Libby Dam, carrying cold, clear water that supports world-class populations of rainbow trout, cutthroat trout, and bull trout. Bull trout are native to the Kootenai drainage and are protected—catch-and-release is required. The river is intimate and wadeable in many sections, with riffles, runs, and undercut banks that hold trout.
Fly fishing is extremely popular on the Kootenai. Dry flies, nymphs, and streamers all produce. The river below Libby Dam benefits from cold, regulated flows that keep water temperatures ideal through summer. Access is available through the fishing access site and at various points along the river corridor. Respect private property and use established access points.
Lake Koocanusa
Lake Koocanusa stretches 90 miles behind Libby Dam (1975) and offers excellent lake fishing within easy reach of Libby. The reservoir holds kokanee salmon, rainbow trout, and lake trout. Kokanee are the primary draw for many anglers, with good populations sustained by FWP stocking. Rainbow trout and lake trout provide additional opportunities. Boat access, shore fishing, and trolling are all productive. The lake’s clear water and mountain scenery make it a popular destination for both fishing and recreation.
Rivers Near Libby
Beyond the Kootenai, smaller streams and tributaries in the Cabinet Mountains and Kootenai National Forest provide creek fishing for trout. These waters flow through forested and canyon settings, offering half-day fishing opportunities. Bull trout and cutthroat are present in many headwater streams—check regulations, as many waters have catch-and-release requirements for native species. The intimate scale of these streams rewards careful, stealthy approaches with light tackle.
