Drought in Ohio: 2024 Overview
Southwest Ohio faced severe drought this year, with dry conditions lingering from mid-June through October. As the heat intensified in September, parts of Ohio, especially southeastern Ohio, slipped into extreme drought. For Ohio’s agricultural sector, the timing couldn’t have been worse—many farmers saw decreased yields, and the USDA classified 22 counties as natural disaster zones. Ponds and wells went dry, and the Ohio Department of Natural Resources urged residents to conserve water. While the September remnants of Hurricane Helene brought a brief reprieve, the drought underscored Ohio’s vulnerability to water shortages.
The Buried Valley Aquifer: A Natural Reservoir Beneath Our Feet
In the heart of this challenge lies an incredible resource, the buried valley aquifer, an underground formation of sand and gravel filled with up to 1.5 trillion gallons of water. Formed by glacial rivers thousands of years ago, this aquifer is like a water "savings account" for Southwest Ohio. The buried valley aquifer is not only a crucial drinking water source for communities but also plays a vital role in keeping our rivers and streams flowing, even during droughts. Connected to the Great Miami River, the buried valley aquifer allows for a steady water exchange, reinforcing the river's flow and stability.
Tracking Water Resources with the Miami Conservancy District
The Miami Conservancy District plays a pivotal role in tracking water levels, inflows, and outflows across the Miami Valley. With an extensive network of 42 precipitation stations, stream gauges, and 101 observation wells, Miami Conservancy District monitors the region’s water status, providing crucial data that shows how the aquifer—and the communities it supports—are managing through drought conditions.

Long-Term Trends: A Stable, Resilient Aquifer
Long-term data collected by the Miami Conservancy District from 2000 to 2024 provides a broader perspective on the BVA’s resilience. Across the 101 observation wells, most showed no long-term decline, despite periodic droughts in 1988, 1991, 1994, 1999, 2012, and 2016. Of the 60 buried valley aquifer wells, only 15 recorded slight downward trends, primarily in urban areas with higher groundwater demand, such as Hamilton, Fairfield, Franklin, and Dayton. This stability shows the buried valley aquifer’s capacity to endure even extended dry periods, though urban demand may place added pressure on this precious resource.
A Powerful Takeaway
The drought of 2024 serves as a reminder of the importance of water conservation and the role natural resources like the buried valley aquifer play in regional resilience. Careful monitoring and data collection ensure we’re prepared, and the buried valley aquifer continues to support the Southwest Ohio region, proving that even in challenging conditions, Ohio’s water future is secure when we prioritize sustainable water use and regional resource management.
As climate patterns evolve, the buried valley aquifer’s role as a natural reservoir remains a reassuring reminder of the need to protect and preserve our water resources for generations to come.
