Prior to doser installation, mean annual pH values in segments of the North Branch were below 5.0, with many falling below 4.0 during low flow periods. After doser installation, mean annual pH rose to over 7.0 for most of the North Branch. This project restored 26 miles of the North Branch above Bloomington Dam, improved water quality in Lake Jennings Randolph, improved 8 miles of tailwater below the dam, and restored 8 miles of tributary waters.
