UTAH LAKE. The largest fresh-water lake in Utah, situated 30 miles southeast of the Great Salt Lake, into which it discharges through the river Jordan (Map: Utah, B 1). It is about 25 miles long and eight miles wide, and lies on the extreme eastern border of the Great American Basin, at the western base of the Wasatch Range, and at an altitude of 4505 feet. It is surrounded by mountains on all sides, but receives its principal drainage from the east. The chief town on its shores is Provo City.
