The Great Salt Lake is the largest natural lake west of the Mississippi River. At the current level the Great Salt Lake is 75 miles long and about 35 miles wide. A slight rise in water level expands the surface area of the lake considerably. The lake level has varied by as much as 20 feet, shifting the shoreline in some places as much as 15 miles.
