bout five miles to the east of Livingston, just off Interstate 90, where Highway 89 turns north, toward White Sulphur Springs. This lower river, from here on down through Big Timber is similar to the water around Livingston, but the riffles and pools are farther apart so there is more unproductive water. The fish populations are not as high as in the upper river and water through town, but there are some very large rainbows and browns to be caught in this stretch. In late summer, wind gusting across hayfields blows a lot of grasshoppers in the river which creates explosive reactions from big fish.|
