MISSOURI RESERVOIR REPORT

Last Updated: December 22, 2025

Missouri has over 200 reservoirs and dams, providing water for drinking, irrigation, and recreation. Major reservoirs include Truman Lake, Table Rock Lake, and Lake of the Ozarks. These reservoirs are fed by streams and rivers such as the Osage, Gasconade, and White River. The area does not have significant snowpack or mountains that contribute to the water supply. The hydrology in the area is typically impacted by seasonal rainfall and drought conditions. In recent years, drought conditions have impacted the water levels in some reservoirs, leading to restrictions on water usage. In 2012, drought conditions caused Truman Lake to reach record low levels. Seasonal trends show that water levels typically decrease in the summer months due to increased water usage and decreased rainfall. Overall, reservoirs and dams play a crucial role in managing water resources in Missouri, but their sustainability is impacted by fluctuations in weather patterns and climate change.
