WERF Releases Report Assessing the Effects of Low DO on Fish

The Water Environment Research Foundation (WERF) recently released a study on The Effect of Wet Weather Driven Dissolved Oxygen Sags on Fish in Urban Systems. In this study, researchers mounted dissolved-oxygen (DO) transmitters on fish to determine their response to wet weather combined sewer overflow events and low DO in the Chicago Area Waterway System. According to the study, largemouth bass were tolerant of low DO, as it had little impact on their movement or habitat choice. This report is free to WERF subscribers
