dc.description.abstractAn intensive study of the East Fork Trinity River (Segment 0819) was conducted September 27-30, 1982. The study area on the East Fork consisted of the reach between the dam on Lake Ray Hubbard to the rivers confluence with the Trinity River. Water quality and hydraulic data were collected from 10 mainstream stations, three tributaries, and five municipal dischargers. No releases were being made from Lake Ray Hubbard so headwater flow into the segment originated from Duck Creek. Stream widths ranged from 26 to 77 feet, discharge increased from 26 cfs in the upper portion to 49 cfs in the lower portion of the segment, stream velocities generally increased downstream (range 0.2-1.5 fps), and river elevation varied less than 6 inches. The poor quality effluent from the City of Garland's Sewage Treatment Plant (BOD5 100 mg/l, TSS 22 mg/l, NH3-N 14.4 mg/l, O-P 4.1 mg/l) appeated to completely dominate the quality in the East Fork Trinity River. A dissolved oxygen sag zone was identified on this study to exist for approximately 15 miles downstream from the City of Garland's discharge into the East Fork. Additionally, the effluent from the City of Mesquite's Sewage Treatment Plant, which had elevated levels of ammonia (21 mg/l), apparently extended the sag of dissolved oxygen further downstream. Throughout most of the East Fork Trinity River levels of ammonia ( > 8 mg/l), orthophosphorus (> 2.5 mg/l), BOD5 (> 9mg/l), and fecal coliform bacteria (> 2000/ 100 ml) were elevated.en_US
