A water quality survey of the Yellow River was performed during July and August, 1978. The primary purpose of the survey was to develop background data and assess the impact of point source waste dischargers on water quality. Results of the survey indicated good water quality throughout the basin during average summer stream flows. Water temperatures in several of the class B coldwater trout streams were above 21¦C which prohibited trout stocking. The elevated stream temperatures occur frequently every summer and are caused by a combination of high ambient temperatures and a reduction in low temperature ground water discharge. Although the chemical and bacteriological analysis indicated the point source waste dischargers from Postville and Luana had little impact on the receiving streams, biological analysis revealed a stressed environment. Most biological sampling stations had a healthy, diverse macroinvertebrate community reflecting the good water quality.
