OHIO RESERVOIR REPORT

Last Updated: December 5, 2025

In Ohio, the state of our dams and reservoirs is a key factor for water management, environmental health, and public safety. One of the major reservoirs, the O'Shaughnessy Reservoir near Dublin, Ohio, has been observed to have a water surface elevation that is below its average. Specifically, the latest data reveals that the O'Shaughnessy Reservoir's current elevation is at 844 feet above the National Geodetic Vertical Datum of 1929 (NGVD 1929), compared to its average of 847.64 feet. This indicates that the reservoir is experiencing lower storage levels than usual for this time of the year. It's important to note that while this report is based on the provided dataset, it is essential to cross-reference with multiple data sources to ensure accuracy and to get a fuller picture of the water storage conditions across Ohio's dams and reservoirs.

The reduced water level in the O'Shaughnessy Reservoir could be attributed to a variety of factors, including below-average precipitation, reduced snowpack, or higher than normal river flows that have not been replenished. Without access to additional data on regional weather patterns, snowpack levels, and river flows, it's challenging to pinpoint the exact cause of the abnormal conditions in the reservoir. However, such deviations can impact water supply for domestic and agricultural use, disrupt aquatic ecosystems, and potentially affect flood control capabilities. It is vital for local authorities and water resource managers to monitor these conditions closely and to cross-reference with hydrological data, weather forecasts, and climate models to manage the resources effectively and mitigate any potential risks associated with these abnormal conditions.

Ohio has several major reservoirs, including Buckeye Lake, Grand Lake St. Marys, and Caesar Creek Lake. These reservoirs are fed by various streams, rivers, and creeks, such as the Licking River, the St. Marys River, and Caesar Creek. Ohio does not have any significant snowpack or mountains that affect its reservoirs. The hydrology of Ohio is primarily influenced by the state's geography, which is characterized by rolling hills and flat plains. Records show that Ohio has experienced major floods in the past, including the Great Dayton Flood of 1913, which resulted in significant damage and loss of life. Drought conditions in Ohio have been relatively rare, but the state has experienced occasional droughts over the years. Seasonal trends show that spring and summer are typically the wettest seasons in Ohio, while fall and winter are drier. Overall, Ohio's reservoirs and dams play a crucial role in providing water for the state's residents and industries.
