To track changes in water availability in the Great Miami River Watershed, the Miami Conservancy District records precipitation, runoff, and groundwater levels to estimate water inflows and outflows for an area of more than 3,630 square miles. The most recent report "Water Quantity Report for the Great Miami River Watershed" has been released for 2023.
The average annual precipitation recorded in the Great Miami River Watershed during 2023 was 36.91 inches. This amount was 5.01 inches below the 30-year average precipitation (1991 – 2020) for the watershed.
The Miami Conservancy District flood protection system stored high water 15 times during 2023. The average annual number of storage events for the five storage basins, over the entire life of the system, is 20. None of the storage events that occurred in 2023 were large enough to exceed Miami Conservancy District's top-10 storage event ranking.
Groundwater levels measured in 2023 ended the year at or close to the levels measured at the beginning of the year. Average annual groundwater levels measured in all index wells have been stable over the long term.
