In 2019 the Little Miami Conservancy rolled out an historic water quality monitoring system to monitor the health of the Little Miami National Wild & Scenic River. YSI Xylem has generously donated 9 EXO1 "Sondes" which LMC has placed at strategic locations along the Little Miami starting in Greene County and stretching downstream through Warren County, Clermont County and Hamilton County. The Sondes records the critical level of dissolved oxygen in the river round the clock every 15 minutes. In 2020 LMC expanded this important effort to partner with Central State University and Groundwork ORV. Stay tuned to the LMC Facebook page for updates.
