April 2, 2025 – With severe storms and heavy rainfall expected across the Miami Valley, the Miami Conservancy District is taking proactive measures to ensure the region remains protected from potential flooding. Forecasts predict up to six inches of rain between Wednesday and Sunday, increasing the risk of rising river levels and localized flooding.
“The Miami Conservancy District is prepared to manage the high water throughout the major river systems and protect communities from destructive floodwaters, said MaryLynn Lodor, General Manager. “We encourage residents to stay informed and follow safety recommendations as the situation unfolds.”
The Miami Conservancy District, which operates and maintains a system of five flood protection dams across the region, is closely monitoring the situation and implementing precautionary actions. Staff will monitor the levels and conditions of the Great Miami, Mad, and Stillwater rivers and operate flood gates as necessary to reduce the risk of riverine flooding.
“Spring rains are not unprecedented, but this system is predicted to be heavier and produce more significant rainfall event and over a large area of our watershed than we typically experience,” said Mike Ekberg, Miami Conservancy District hydrologist. “Our dams will begin to store water, temporarily creating reservoirs behind them to manage river flow and prevent downstream flooding.”
Flood Protection System in Action
The Miami Conservancy District flood protection system has successfully safeguarded the region from catastrophic flooding for over a century. As river levels rise, the following measures are being activated:
• Storage Events at All Five Dams: MCD anticipates significant water storage behind the dams to manage flow downstream.
• Gate Closures and Pump Station Operations: Gates at key locations will be closed to prevent backflow into protected areas, including the cities of Piqua, Troy, Dayton Miamisburg, West Carrollton, Franklin, and Hamilton, and the Piqua pump station will be in operation as needed.
• 24-Hour Staffing at Key Locations: If necessary, the staff will be on duty around the clock at multiple dams and flood protection features to ensure rapid response and adjustments as conditions evolve.
Current River and Weather Conditions
• Forecasted rainfall: 3-4 inches over the next 72 hours, 5-7 inches over the next five days.
• River levels are expected to rise rapidly starting Wednesday night, with crests anticipated over the weekend.
• Severe storms could bring damaging winds, hail, and possible tornadoes in addition to heavy rainfall.
Public Safety and Precautions
Residents in flood-prone areas are urged to stay informed and take necessary precautions. Miami Conservancy District advises the following safety measures:
• Stay tuned to local news and weather updates for the latest conditions.
• Avoid travel on flooded roads and never attempt to drive through high water.
• Be prepared for possible road closures and high-water warnings in low-lying areas.
