Through its Civil Works Program, the Corps carries out a wide array of projects that cover coastal protection, flood protection, hydropower, navigable waters and ports, recreational opportunities and water supply. The Corps’ Engineering Research and Development Center (ERDC) operates the Aquatic Nuisance Species Research Program with the goal of minimizing adverse impacts and maximizing control opportunities with respect to aquatic invasive species. The ERDC also has an Aquatic Plant Control Research Program, which is the only federally authorized research program in the Nation directed to develop technology for the management of nonnative aquatic plant species. The Corps interacts with the public through numerous boating facilities at all of the reservoirs under its jurisdiction by posting educational signs at public access points (e.g., boat ramps) warning boaters to check for aquatic invasive species hitchhikers. The Corps educates and informs marina employees, boaters, and the general public about problems associated with improper sewage disposal and encourages the use of pump out stations. It uses a variety of outreach tools, including displays, publications, workshops, promotional items, education programs and websites to reach target audiences. Surveys of Corps reservoirs are conducted to monitor existing aquatic invasive species populations and to detect new infestations. Members of the Corps’ natural resource management staff are also trained to recognize and report the occurrence of aquatic invasive species. In Georgia, the Corps’ involvement in aquatic invasive species management is primarily related to the occurrence of nuisance populations of aquatic plants in Corps-operated navigation and multi-purpose reservoir projects including Lake Seminole and the Walter F. George Reservoir.
