IN WATER CULTURAL RESOURCES SURVEY FOR THE DALTON PIPELINE ETOWAH RIVER CROSSING BARTOW COUNTY,GEORGIA FERC DOCKET CP15117000

This report presents the results of a submerged cultural resources pedestrian and remotesensing

survey of the area of potential effect (APE) in the Etowah River, Bartow County,

Georgia, where the Dalton Expansion Pipeline Project is proposed to traverse by open cut

trenching. SEARCH was contracted by Cardno, Inc. (Cardno) on behalf of Transcontinental Gas

Pipe Line Company, LLC (Transco).

SEARCH Maritime Archaeology crews surveyed the APE for potential rock dam/fish weir cultural

features by means of pedestrian and snorkeling observations, aerial photography by means of a

tower-mounted camera with Garmin Wide Area Augmentation System (WAAS) Global

Positioning Systems (GPS) positioning, and ground-penetrating radar (GPR) remote sensing with

Differential GPS (DGPS) positioning. Both the aerial photographic and GPR data were post

processed for analysis and figure production.

Water levels were drawn down to low levels by means of closing the flow from the Allatoona

Dam for a limited time as a courtesy by the US Army Corps of Engineers (USACE). This resulted

in water levels ranging from one to just over six feet in the APE study area and allowing the

majority of the 300-foot study area to be visually inspected by wading and the remainder to be

investigated with mask and snorkel. In addition, aerial photographs and GPR data were

gathered to assess their usefulness for recording rock built features.

Background study of Etowah River fish weirs or rock dams, presented in more detail in this

report, indicates that such features would be alignments of rocks that would occur in low slope

shoal areas that would extend, or would have extended, across the entire width of the river.

These alignments could be V-shaped, W-shaped, or full linear dams including L-shapes, across

the river. Damaged sections of such features would be indicated by clusters of rocks in linear

sets. No such features, or portions of such features, were found by means of pedestrian, aerial

photographic, or GPR operations in the study area. No additional work is necessary in the

Dalton Expansion Etowah River crossing APE.
