Drainage Areas of Texas Streams Colorado River Basin

Data on the drainage areas of Texas streams are being appropriately com piled in cooperation with the Texas Department of Water Resources so that information of uniform accuracy and reliability will be available for hydrau lic, hydrologic, or general engineering use. Only recently has large-scale topographic-map coverage of the Colorado River basin been completed. The mapping was largely financed through a cooperative program between the Texas Department of Water Resources and the U.S. Geological Survey. This report gives the drainage areas as determined by measurements at 429 points within the Colorado River basin. These data are tabulated in table 1, which gives the latitude and longitude of the points of determination, the drainage area in square miles above each point, and the distance in miles from the point to the mouth of the stream.Waller Creek Working Grou
