Perry G. Olcott, D.W. Ericson, P.E. Felsheim, W.L. Broussard
1978, Hydrologic Atlas 582
The Lake Superior watershed is mostly a highland, generally 1,200 feet (366 meters) to 2,000 feet (610 meters) above mean sea level. It extends from Duluth to the Canadian border. Both maximum and minimum altitudes for Minnesota occur in the watershed; 2.301 ft (701 ) at Eagle Mountain, about 12 mi...

Mareta N. West
1978, Oil and Gas Investigation Chart 86
The U.S. Geological Survey (USGS), in a cooperative agreement with the U.S. Department of Energy (DOE), is participating in the Eastern Gas Shales Project.

Backwater at bridges and densely wooded flood plains, Bogue Chitto near Summit, Mississippi
B.E. Colson, C. O. Ming, George J. Arcement
1978, Hydrologic Atlas 592
New techniques for predicting water-surface profiles, needed in the design of economical, structurally sound, and environmentally compatible stream crossings, are under investigation.  The investigation has accelerated with the advent of digital computers capable of analyzing large quatities of data.  Among the techniques is the development of two-dimensional (2-D) digital models....
