Archaeological and Historical Study Report Morgan Falls Project FERC # 2237 Fulton and Cobb Counties, Goergia

During June and November 2005, and January 2006, Brockington and Associates, Inc., conducted historical research, archaeological reconnaissance, and limited surveys of shoreline areas in the Morgan Falls Hydroelectric Project (FERC #2237). These investigations were conducted for Georgia Power Company (Georgia Power) as part of the Federal Energy Regulatory Commission (FERC) hydroelectric project relicensing process (18 CFR Part 4.51[4], Applicationfor License for Major Project-Existing Dam). Georgia Power implemented shoreline investigations to comply with requirements of the National Historic Preservation Act of 1966 (as amended) and relevant regulations. The Morgan Falls Project is located on the Chattahoochee River, north of Atlanta between Roswell and Sandy Springs, Georgia. Project lands encompass approximately 1,028 acres in Fulton and Cobb Counties, Georgia. Nearly 627.4 acres ofthis property are inundated, encompassed by approximately 29.6 km (18.4 mi) of shoreline. Archaeological reconnaissance and limited shoreline surveys were conducted during a 2- foot drawdown of the project impoundment. Historical research documented previously recorded archaeological sites within the Federal Energy Regulatory Commission (FERC) project boundary. The project boundary extends approximately 7.5 miles upstream from the Morgan Falls facility and encompasses areas from the 868-foot contour and below. Archaeological reconnaissance identified shoreline segments within the Morgan Falls Basin with moderate to high potential for archaeological resources. Limited surveys of selected shoreline segments identified no new archaeological sites or isolated finds. Seven previously recorded archaeological sites were reexamined during the shoreline survey. Based on results of these investigations, two of the previously recorded archaeological sites (9FU216 and 9FU228) are located either within or adjacent to the FERC project boundary. The remaining five previously recorded sites reexamined during 11 this investigation do not extend into the FERC project boundary. Site 9FU216, a prehistoric rockshelter, is recommended ineligible for the NRHP, and no further management considerations are warranted for this site. Site 9FU228, the remains of a nineteenth-century mill, is eligible for the NRHP. This site is currently monitored and maintained by the National Park Service, therefore additional management by Georgia Power should not be required.
