Water quality and dynamics at mouth of the Great Miami River and Lawrenceburg, IN with Michael Miller

Join us for a presentation from Michael Miller.

For the past 15 years, the Citizens Volunteer Water Quality Monitoring program monitored E. coli, nutrients, and conductivity to show the linkage between the Ohio River, the Great Miami River and the Whitewater River in modifying the chemistry of the lakes of Oxbow Inc. These ecosystems are dependent upon timing and magnitude of large discharge events on the GMR, the Whitewater River, and the Ohio River. Fish and macroinvertebrate composition depends on these flood events and the low water events in early autumn. Most of the big fish are present only during the winter-spring floods, leaving the small fish as the food for the fish-eating birds: the white pelicans, white egrets, great blue herons, green herons and kingfishers.
