The Kansas Department of Health and Environment (KDHE) has rescinded a stream advisory for the Marais des Cygnes River near Osawatomie, Kansas, issued on May 31, 2023. Recent rains have elevated the streamflow in the river such that the volume of wastewater bypassed has been dwarfed by the current runoff. While the bypass of wastewater has been corrected, the current runoff in the river presents safety issues for those entering the stream. These concerns include elevated levels of bacteria and high flow velocities. The public is urged to use caution in and around the Marais des Cygnes River and take proper precautions and hygiene to prevent prolonged exposure to river water during these wet conditions. Bacteria levels should decline to safe levels as the river flows recede once the rain has stopped.
