Lake Seminole is a large reservoir formed by damming the Chattahoochee and Flint Rivers. Current management objectives focus on decreasing the dense population of the invasive plant, Hydrilla verticillata, which can cover 55% of the lake. We collected a sediment core from each side of the lake in order to reconstruct the allochthonous inputs and ecological responses since the dam was constructed. Results show that the Chattahoochee side of the lake has experienced multiple periods of differing heavy metal in-‐ puts but has maintained a constant Hydrilla population. The Flint side of the lake has stored large amounts of phosphorus in the sediments as well as maintained a dense population of the cyanobacterium, Lyngbya sp., in concert with the Hydrilla population. In addition, sediment cores contained substantial numbers of the invasive clam, Corbicula fluminea. These findings suggest that the two sides of Lake Seminole are different depositional and benthic environments while maintaining similar and dense Hydrilla populations.
