GEOLOGICAL SURVEY OF ALABAMA. 



The initial point is top of left abutment at the edge toward 

 the river, on the downstream side of the -bridge, from which 

 side soundings and meter measurements are made. The rod 

 of wire gage is nailed to outside guard rail, downstream side, 

 next to the last panel of stationary bridge before reaching the 

 pier at end of draw span. The rod is 14 feet long and divided 

 to feet and tenths. The bench mark is the top of capstone on the 

 large circular center pier of turn span. It is 26.80 feet above 

 datum of gage at downstream side of pier. 



The drainage area is 6,850 square miles, and is mapped on 

 atlas sheets Springville, Anniston, Gadsden, Fort Payne, Rome, 

 Tallapoosa, Marietta, Cartersville, Suwanee, Ellijay, Dalton, 

 Cleveland, Ringgold, and Stevenson of the United States Geo- 

 logical Survey.
