The upper portion of the river includes four major forks -- Clear, West, Elm and East -- and extends approximately 160 river km southeast of Dallas to near Trinidad. In the north, the drainage basin is highly urbanized, while the southern portion is primarily rural, with pastures, rangeland, and cultivated cropland. The population along the headwaters of what was once a prairie stream has grown to more than 3 million people, who get potable water from the Trinity watershed. Historically, river water quality has been poor, but wastewater discharges and storm runoff from growing urban areas have exacerbated the problemP 2000 FRESHWATER POLLUTIONPlanningQ5 01505 Prevention and controlRiver FlowRiver waterRunoffSW 3070 Water quality controlUSAwaterWater qualityJournal
