Hydrogeologic Assessment and Simulation of Stream-Aquifer Relations in the Lower Apalachicola-Chattahoochee-Flint River Basin
Current hydrologic information and groundwater-flow modeling in the lower Apalachicola - Chattahoochee - Flint (ACF) River Basin (inset map) are insufficient to describe effects of time-variant irrigation pumping on streamflow. Therefore, existing models cannot accurately predict ground-water or streamflow conditions during a growing season. The Georgia Department of Natural Resources...
Lake Seminole Hydrologic Analysis - USGS
Water management in the lower Apalachicola-Chattahoochee-Flint (ACF) River Basin has long concerned Alabama, Florida, and Georgia due to competing freshwater demands. Numerous studies have explored the complex relationships among hydrologic components and natural and human-induced stresses. However, prior research lacked mechanisms to collect real-time data critical for developing a precise water...
Geohydrology and Effects of Climate and Pumpage Change on Water Resources of the Aucilla–Suwannee–Ochlockonee River Basin, South-Central Georgia and Adjacent Areas of Florida, Progress and Significant Results, 2006—2007
Episodic droughts and increased pumpage since the mid-1970s have caused unprecedented ground-water level decline in the Upper Floridan aquifer in much of the roughly 8,000 square-mile Aucilla-Suwannee-Ochlockonee (ASO) River Basin. To address concerns about water availability, USGS worked with Georgia Environmental Protection Division to improve understanding of the hydrogeologic framework and...

Southwest Georgia Agricultural Water Conservation and Metering Program
During 2008-2015, the U.S. Geological Survey investigated methods to estimate agricultural water use and growing season pumping rates through the analysis of water-meter data throughout southwest Georgia. Reports are available by year.
