Southwest Montana Lakes

The major lakes of Southwestern Montana are mainly concentrated along the Madison River drainage.  These lakes tend to be on the shallow side and have good populations of Mayflys, making them excellent targets for fly fisherman.  Known as "Gulpers", the large Rainbows that feed on these hatches draw anglers from far and wide.  Boats or float tubes are very useful here in order to cover more water and reach fish that are rising out of reach from the shore.
