A.E. Weissenborn 1946 <Proposals for the improvement of navigation on the Trinity River in Texas have been under consideration for many years. A Federal project for the constricution of a sex-foot channel to Dallas, together with the necessary locks and dams was authorized in 1902. Under the terms of this act and subsequent legislation seven locks and dams and one auxiliary dam were constructed by the Corps of Engineers, U. S. Army, but the project was never completed. The River and Harbor Act of September 22, 1922, directed the abandonment of the project but provided for a six-foot channel from Liberty to the mouth of the Trinity River; the six-foot channel was maintained until 1930, when it was abandoned owing to lack of traffic. In 1945 Congress approved the construction by the Corps of Engineers, U. S. Army, of a number of reservoirs for flood control along the upper Trinity River. Congress also approved the excavation of a nine-foot channel from Liberty to the mouth of the Trinity River. It did not authorize the improvement of the Trinity River above Liberty, but the Corps of Engineers was authorized to investigate further the economic justification of a nine-foot channel from Liberty to Fort Worth.</p> <br/> <p>In March 1945 Colonel George R. Goethels, Chief of the Civil Works Division of the Corps of Engineers, requested the Director of the Geological Survey, United States Department of the Interior, to prepare a report on the mineral resource of the area that, according to economic studies made by the Corps of Engineers, would be affected by the canalization of the Trinity River to Fort Worth. As a consequence, the staff of the Geological Survey's Regional Office in Rolla, Mo., was assigned the task of preparing the desired information. A. E. Weissenborn, acting Regional Geologist, called on Major H. R. Norman, Division Engineer of the Corps of Engineers, U. S. Army, and discussed with him the purpose, scope, and form of the proposed report. Following this discussion, Dr. John T. Lonsdale, Director of the Bureau of Economic Geology of the University of Texas, at Mr. Weissenborn's request, agreed that the Bureau of Economic Geology should participate in the preparation of the report. My. Weissenborn also called on Robert H. Dott, Director of the Oklahoma State Geological Survey at Norman, Oklahoma. The Oklahoma Geological Survey was unable to participate in writing the report, but was very helpful in supplying published and unpublished or out-of-print information on the mineral resources of Oklahoma.</p> application/pdf 10.3133/ofr4630 en U.S. Geological Survey Mineral resources of the Trinity River tributary area in Texas and Oklahoma reports
