Coralville Water Quality Study, Water Year October 1, 1977 to September 30, 1978,
Abstract
The Coralville Reservoir Water Quality Project was initiated in 1964 and has continued without interruption since that time. The purpose of the study has been the determination of the effects of a flood control reservoir on the chemical and biological characteristics of its parent river. Samples were collected from the Iowa River upstream from the reservoir; at Johnson County Road W-8 (formerly '0'); from the top, mid-depth and bottom at the reservoir at the Mehaffey Bridge downstream from the Lake MacBride spillway; and from the Iowa River at two points downstream from the reservoir about one mile below the Coralville dam and at the University of Iowa Water Treatment Plant. During the current water year, samples were collected on a weekly basis and analyzed for temperature, conductivity, turbidity, dissolved oxygen, Ph, carbon dioxide, alkalinity, ammonia and orthophosphate. All other parameters, including plankton, were determined on a twice monthly basis.
