From the outlet at Lewis Lake the river does not travel far before dropping 30 feet as Lewis Falls. The falls are easily seen from the main road, but parking and taking a short hike up the south side the river allows you to view the falls from a fenced overlook. If you adventure beyond the lookout on self-made trails you can be at the brink of the falls and view the beautiful and broad river before it reaches the brink. While the falls are only 30 feet in height, the width of this waterfall is the full width of the river and is quite impressive. You can often see anglers casting their line just below the falls and from there downstream about 2 miles before the river enters the canyon.
