The report on the Guadalupe River Basin has been prepared to aid in the continued development of the water pollution program to protect the waters of the basin. It is a summary of information and data available as of August 1951 on the uses to which the water resources are put, the pollution reaching the watercourses and the damages resulting from that pollution, the benefits which may result from pollution prevention and abatement, the pollution prevention measures now in effect, and those which are required. This report will serve to publicize the water pollution situation and direct the responsibility for needed corrective measures to municipalities and industries involved. (Author Modified Abstract)
