Travel time for solutes, upper Sabine River basin, Texas, April 16-30, 1972

The U.S. Geological Survey, in cooperation with the Sabine River Compact Administration, conducted time-of-travel studies in the Sabine River Basin on April 16-30, 1972. One study was made on the main stem of the Sabine River in four reaches from Lake Tawakoni to Toledo Bend Reservoir, a distance of 219 miles. Two other studies were made on reaches of Lake Fork Creek and Big Sandy Creek. The purpose of these studies was to provide travel-rate data to be used by the Sabine River Authority of Texas in constructing a hydrologic model of the basin.
