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
