Water Quality Changes Due to Impoundment
This article discusses 15 years of stream flow, turbidity, and coliform organism data from the Iowa River at Iowa City. The Iowa River drains 4,375 sq. mi. of extensively farmed, fertile prairie soil, 3,271 sq. mi. of which are above Iowa City. The University of Iowa and Iowa City each maintain separate water treatment plants, each using the Iowa River as the primary supply. All samples were taken from the raw water intake of the university plant, 5 or 6 days a week, between 1950 and 1965. Stream flow measurements were furnished by the U.S. Geological Survey. Bacterial analyses were performed by the Iowa State Hygienic Laboratories. The Coralville Flood Control Dam, about 6 miles above Iowa City, was put into operation Sep. 18, 1958. This divides the period of record so that “before” and “after” water quality data can be analyzed.
