Discussion from McGrain and Currens (1978)

Grant County is in the highly dissected Outer Bluegrass Region. Ridgetop elevations in excess of 900 feet are common. Local reliefs along principal drainage lines are generally in excess of 150 feet, but in places are almost 300 feet.

Eagle Creek crosses the western part of the county. It is the largest stream in Grant County and has valley widths of 1/2 mile or more. The lowest elevation, approximately 530 feet, is the point where Eagle Creek leaves the county.

The highest elevations in the county are found along and adjacent to Ky. 330, 2 miles southwest of Corinth. Here, on a drainage divide between Eagle and Three Forks Creeks, elevations of 1,000 feet have been recorded. Many elevations on the north-south divide between the Licking River and Eagle Creek drainage systems in the Dry Ridge-Williamstown area are between 950 and 980 feet. Farther north they decline to approximately 920 feet at the Grant-Kenton County line.

The elevation of Williamstown, the county seat, is 974 feet. Other elevations are Corinth, 980 feet; Crittenden, 920 feet; Dry Ridge, 958 feet; Elliston, 588 feet; Jonesville, 914 feet; and Mount Zion, 925 feet.

The spillway elevation of Boltz Lake is 826 feet; the spillway at Corinth Lake is 840 feet, and the one at Williamstown Lake is 785 feet.

The 7.5-minute topographic quadrangle maps that cover Grant County are shown, by name and by index code (Kentucky Natural Resources and Environmental Protection Cabinet) on the index map.
