Lake Koocanusa Professional Review and Guide
"Northwestern Montana contains some of this nation’s most magnificent scenery, ranging from the frosty, snow-laden peaks of the Cabinet Mountains—which contain several species of pine and fir trees, abundant larch, and an impressive grove of western red cedar—to the floor of the Kootenai River Valley and some of Montana’s most productive trout waters.
In 1973 alone, approximately 1 million fingerlings were planted. Since that time FWP has stabilized its plantings to an annual total of approximately 100,000 planted in the tributaries. Besides the planted cutthroat trout, the reservoir now contains virtually all of the fish that inhabited the Kootenai River prior to impoundment by Libby Dam. In fact, kokanee salmon that migrated from British Columbia down to the reservoir made up over 40 percent of the game fish caught in Lake Koocanusa by September 1981. In addition to cutthroat trout and kokanee salmon, the reservoir now contains rainbow and bull trout, mountain whitefish, burbot (or ling), suckers, peamouth, and squawfish. British Columbia began planting Kamloops rainbow in the reservoir in 1985 and FWP followed suit in 1988. The nongame fish population has dramatically increased in the reservoir, so anglers should not be surprised to hook a few peamouth and squawfish."
