Fishing At Lake Koocanusa
AKA: Koocanusa Reservoir
What to fish for...
Fishing for largemouth bass, rainbow trout, cutthroat trout, brook trout, pumpkinseed sunfish, yellow perch, kokanee salmon and northern pike at Lake Koocanusa in Montana.
Over half of Lake Koocanusa is in Montana, the remainder of the lake is in Canada. Along the USA shores are scattered camping areas. The lake boasts 28,800 surface acres and approximately 150 miles of shoreline, and is located in the northwest corner of the state. There various areas accessible for fishing from the bank, but many of the better fishing areas can only be reached via boat. Several boat launch ramps are located on either side of the lake. These water are teeming with healthy populations of bass, trout, sunfish, perch, kokanee and pike. Fishing success is enhanced annually with stocking of trout. And, because the lake is in a remote area, it does not get the fishing pressure other Montana lakes receive.
