OHIO RESERVOIR REPORT

Last Updated: February 2, 2026

Ohio's dams and reservoirs play a critical role in water supply, flood control, and recreation. Recent observations indicate that most reservoirs are maintaining typical water levels for this time of year, with one notable exception. The O'Shaughnessy Reservoir near Dublin, Ohio, has a reported storage level slightly above the average. The current measurement is at 848 feet, marginally surpassing the average of 847.63 feet, as per the Lake or reservoir water surface elevation above NGVD 1929. This slight rise in water level, based on the latest observation dated February 2, 2026, could potentially be linked to localized weather patterns, increased precipitation, or upstream water management decisions. It's important to note that these variations are within expected operational ranges and there are no immediate concerns for safety or water management.

Across Ohio, major dams and reservoirs such as Hoover Dam, Caesar Creek Lake, and Senecaville Lake are closely monitored to detect any abnormal conditions. While the O'Shaughnessy Reservoir's levels are above average, they are not indicative of a broader trend affecting Ohio's water systems. These conditions might not be related to the snowpack, as Ohio's climate typically involves less impact from snowpack melt compared to Western states. River flow rates and recent precipitation events are likely more influential factors in the current reservoir levels. It is imperative for state water management authorities to continuously monitor these indicators and cross-reference them with historical data to ensure proactive measures are taken when necessary. The overall stability of Ohio's dams and reservoirs is indicative of effective water management practices that respond to both natural fluctuations and human impact on the watershed.

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.
