Below is a message from Miami Conservancy District - MCD regarding the excessive rainfall which recently occurred:
Over the past week, the Great Miami River Watershed received between 2.5 and 7 inches of rainfall. As runoff moved through the watershed, the Miami Conservancy District flood protection system responded across the region to manage elevated river levels and reduce flood risk for communities, businesses, and critical infrastructure.
During this event, Englewood, Taylorsville, Huffman, and Germantown dams stored floodwater, with peak storage reaching 4.6 billion gallons. This ranks as the 141st largest storage event in MCD history.
River levels reached the First Action Stage in Dayton, West Carrollton, Miamisburg, Franklin, Middletown, and Hamilton. MCD staff monitored conditions around the clock and closed floodgates in West Carrollton, Middletown, and Hamilton as part of coordinated flood operations.
This was the 8th high water event of 2026 and the 19th separate storage event this year.
These moments are an important reminder of the scale and value of the region’s flood protection infrastructure. Water falling across rooftops, roads, fields, parking lots, and streams throughout the watershed ultimately moves downstream together. Managing that water requires a regional system, and a regional commitment.
For more than a century, the Miami Conservancy District flood protection system has helped safeguard lives and property while creating the conditions for Southwest Ohio communities to grow and thrive. From homes and hospitals to roads, utilities, and economic centers, the protection provided by this system supports daily life and long-term regional prosperity.
Just as important are the people behind the system. MCD staff continue to monitor conditions 24/7, operate flood infrastructure when needed, and provide the expertise necessary to keep the system functioning reliably during high water events.
Thank you for your continued partnership and support as we work together to protect and strengthen the region.
