456 NOUS41 KILN 252022 PNSILN OHZ053-062-260830- Public Information Statement National Weather Service Wilmington OH 422 PM EDT Mon Aug 25 2025 ...CHANGES IN FLOOD CATEGORY LEVELS AT THE NWS RIVER FORECAST POINT ALONG THE MAD RIVER NEAR SPRINGFIELD, OH WILL CHANGE ON SEPTEMBER 16... Effective Tuesday September 16, 2025, river flood categories for the Mad River near Springfield will change. The U.S. Geological Survey and Miami Conservancy District have moved the gage downstream of the previous location, prompting a change in the equivalent water surface elevation. So a flood as measured by the new gage location will read differently/higher than the previous gage location. As a result of this move, all flood category stages will also change. The changes to these flood levels were closely coordinated with the USGS, Miami Conservancy District and Clark County Emergency Management. The new critical levels are: Action stage will be raised to 9 feet, from the existing Action stage of 6 feet. Flood stage/minor flood level will be raised to 12 feet, from the existing Flood stage/minor flood level stage of 8 feet. Moderate flood level will be raised to 16 feet, from the existing Moderate flood level of 13 feet. Major flood level will be raised to 18 feet, from the existing Major flood level of 15 feet.
