Map Explanation

Water-surface elevations at this gage are based on a 1-foot change in elevation at the Tar River below Tar River Reservoir gage. A 1-foot change in water-surface elevation at the Tar River below Tar River Reservoir gage does not necessarily result in a 1-foot change in downstream gages.

Base map is hill shade derived from LIDAR. Roads are coverages obtained from the North Carolina Department of Transportation. Orthophotography is from USDA 2005 National Agriculture Imagery Program.

(Green square) = station location.

Gage Height (GH) and Water-Surface Elevation are rounded to the nearest tenth of a foot.

1:24,000 scale shows inundated area near streamgage.

1:12,000 scale shows greater detail, including road names.
