Abstract

A series of seven studies of the quality and quantity of low flows in a 35.5-mile reach of the Colorado River upstream from Colorado City, TX, were made from February 1975 to March 1978 to delineate areas of saline inflow. Salt-load trend studies for three long-term continuous streamflow and daily water-quality stations show that the salinity of the flow upstream from Ira (mile 826.3) increased significantly after 1963, but decreased significantly after 1970. The low-flow and salt-load trend studies indicate that part of the salinity in the flow of the Colorado River has resulted from the inflow of oil-field brine; but preponderant evidence indicates that the major part of the salinity is of natural origin. Neither the ban on open-pit disposal nor pumping of saline ground water has significantly reduced the salinity of flow downstream from Cuthbert (mile 810.6). (USGS).
