Effects of Channel Dams on Dissolved Oxygen Concentrations in Northern Illinois Streams
The principal objective of this study was to gather physical data concerning the aeration characteristics of the dams for use in calibrating weir formulas developed in Great Britain. This entailed measuring upstream and downstream DOs and temperatures for extended time periods and determining the physical measurements and characteristics of the dams. In all, 53 different structures exist at 48 locations on study area streams. Forty of the 53 structures were sampled at 15-minute intervals for at least 4-hour segments. It was concluded that most channel dams and weirs studied significantly affect water quality in almost all major study area streams. These effects should be incorporated into any mathematical model dealing with dissolved oxygen.
