P.W. Skinner J.F. Blakey 1973 <p>The proposed water-quality network for the Sabine River Basin of Texas and Louisiana consists of nine monitoring stations, a central control station, a slave-central station, and a leased-line telecommunications system. This monitoring network would provide continuous transmission of water-quality data to the office of the water manager.</p> <p>Level I operations at a proposed site would monitor current and potential problems, water-quality changes in subreaches of streams, and water-quality trends in time and place. Level II operations would monitor current or potential problems only. An optimum system would require Level I operations at all nine stations. A minimum system would require Level II operations at most of the stations.</p> application/pdf 10.3133/ofr7325 en U.S. Geological Survey A network for continuous monitoring of water quality in the Sabine River basin, Texas and Louisiana reports
