The report on the quality of the waters of the Jordan River Basin is based on information obtained during the June and August 1972 field investigations. The first of the studies in the Basin consisted of a short-term, intensive water quality study of Emigration Canyon conducted during the week of June 19-25, 1972. Also included in this study was a limited nutrient investigation of the Jordan River in the vicinity of a proposed impoundment on the river. A second intensive effort during the period August 13-26, 1972, involved the entire length of the Jordan River from Utah Lake to the Great Salt Lake, and was focused on water quality and biological activity in the river.
