GEORGIA RESERVOIR REPORT

Last Updated: February 23, 2026

In the current assessment of the nation's dams and reservoirs, we observe a diversity of storage levels that highlight the varied hydrological conditions across the country. With the latest observations in hand, several key trends have emerged. Notably, significant surpluses are present in California's reservoirs like Lake Almanor and Don Pedro Reservoir, where storage levels have surpassed historical averages, likely due to robust winter precipitation and runoff. Conversely, Lake Powell in Arizona and Elephant Butte Reservoir in New Mexico are experiencing alarmingly low water levels, reflecting prolonged drought conditions that have beleaguered the Southwest. These storage deviations can have far-reaching implications for water supply, ecological health, and flood control.

Zooming into the specifics, reservoirs such as San Luis Reservoir in California are seeing an uptick in storage, possibly benefiting from the state's complex water management strategies and recent wet weather patterns. On the other end of the spectrum, Colorado's Granby Reservoir and Green Mountain Reservoir have lower than average storage levels, signaling potential water allocation challenges if the trend persists. These anomalies in reservoir conditions are intrinsically linked to factors such as snowpack levels, river flows, climate variability, and water consumption patterns. Hydrologists and water managers monitor these indicators closely to strategize responses to ensure water security and environmental stewardship, balancing the needs of urban centers, agriculture, and natural ecosystems.

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.
