GEORGIA RESERVOIR REPORT

Last Updated: December 22, 2025

Across the nation, dams and reservoirs play a vital role in water supply, flood control, and ecosystem management. However, these critical resources are subject to the whims of weather, climate change, and human demand. The latest observations reveal a mixed picture, with some reservoirs experiencing surpluses due to above-average precipitation, while others face drought conditions, reflecting irregularities in snowpack melting and river flows.

For instance, Lake Powell in Arizona, the second-largest man-made reservoir in the country by maximum water capacity, is currently facing significantly low water levels with only about 44% of its average storage reported, a stark illustration of the prolonged drought impacting the Colorado River Basin. Contrastingly, Lake San Antonio in California is experiencing a surplus, holding nearly double the average storage, likely due to recent heavy rains. Similarly, New Melones Reservoir in California has a storage level well above its average, which could be beneficial in addressing the state's water needs amidst variable climatic conditions. Strategic management of these water resources is more crucial than ever, as water management authorities strive to balance environmental sustainability with the demands of urban development, agriculture, and recreation. The data underscores the importance of continued monitoring and adaptive reservoir management in the face of increasingly unpredictable weather patterns.

Georgia relies heavily on reservoirs and dams to meet its water needs. Major reservoirs in the state include Lake Allatoona, Lake Lanier, and Lake Hartwell. These reservoirs are primarily fed by streams and rivers such as the Chattahoochee, Etowah, and Savannah. The hydrology of the area is influenced by the Appalachian Mountains, which provide snowpack that contributes to streamflow. However, drought conditions can impact the availability of water in these reservoirs. In 2007, Lake Lanier reached record low levels due to a severe drought. Seasonal trends also play a role in water availability, with higher streamflow during the winter and spring months. Overall, reservoirs and dams play a crucial role in managing water resources in Georgia, ensuring that residents have access to a reliable supply of water.
