IMPROVEMENTS OF RIVERS AND HARBORS IN THE SAVANNAH, GA., DISTRICT This district comprises a very small portion of southwestern North Carolina, western South Carolina, eastern Georgia, and a small portion of northeastern Florida embraced in the drainage basins tributary to the Atlantic Ocean between Port Royal Sound, S. C., and the harbor at Fernandina, Fla. It includes the Atlantic Intracoastal Waterway between these points. District engineer: Lt. Col. Robert Erlenkotter, Corps of Engi neers. Division engineer of the South Atlantic Division, Atlantic, Ga., comprising the Wilmington, N. C., Charleston, S. C., Savannah, Ga., Jacksonville, Fla., and Mobile, Ala., districts: Col. B. L.

JOHNS RIVER, FLA. (SAVANNAH DISTRICT) Location. This section of the waterway connects Port Royal Sound, S. C., with Fernandina, Fla. (See U. S. Coast and Geodetic Survey Charts Nos. 838-841, inclusive.) For Cumberland Sound to St. Johns River section see page 576. Previous projects-between Savannah, Ga., and Fernandina, Fla. Previous improvements in this section were authorized by River and Harbor Acts of August 2, 1882, August 11, 1888, July 13, 1892, and March 3, 1905. For further details see pages 1814, 1821-1823, Annual Report for 1915, and page 585, Annual Report for 1938. Existing project. This provides for a waterway 12 feet deep at mean low water and not less than 90 feet wide between Port Royal Sound, S. C., and Savannah, Ga.; for a waterway 12 feet deep at mean low water, with widths of 90 feet in land cuts and narrow streams and 150 feet in open waters, between Savannah, Ga., and Fernandina, Fla., to follow in general the alinement of the existing waterway, except for such cut-offs or other changes in the route as may be found desirable and justified by the resultant benefits to navigation; and for a suitable anchorage basi at Thunderbolt, Ga. The total distance from Port Royal Sound S. C., to Fernandina, Fla., is 165 miles. The project also provides for the following: (1) removing logs and snags from Generals Cut, Ga.; (2) an alternative and more protected route 7 feet deep at mean low water from Doboy Sound to Brunswick Harbor, vi Darien River, Three Mile Cut, Altamaha River, One Mile Cut Buttermilk Sound, Mackay River, Back River, Clubbs Creek, and Plantation Creek; (3) a protected channel 7 feet deep at mean low water and 75 feet wide around St. Andrews Sound, extending from the main route of the waterway in Jekyll Creek through Jekyl Sound, Little Satilla River, Umbrella Cut, Umbrella Creek and its south branch, through Dover Cut to Dover Creek, thence up Dover Creek and through a narrow neck of land to Satilla River, thence through a land cut south of Todd Creek and through Floyd Creek to the main route of the waterway in Cumberland River; (4) a channel 5 feet deep at mean low water and 50 feet wide to connect Baileys Cut to Satilla River and Dover Creek, Ga.; (5) a loop 8 feet deep at mean low water to reach the wharves at the southern end of Cumberland Sound; (6) an alternative route feet deep and 150 feet wide in that part of Frederica River, Ga., not now traversed by the main route, at no additional cost to the United States. In general, the work is to be accomplished by dredging, supplemented by training walls as necessary. The mean tidal range between Port Royal, S. C., and Fernandina, Fla., is from 6 to 8 feet, with fluctuations from 12 to 21 feet, due to winds and lunar phases. The project has been completed at a cost of $763,599.20 for new work, exclusive of amounts expended under previous proj ects. The latest (1951) approved estimate for annual cost of maintenance is $300,000. The existing project was authorized by the following river and harbor acts: Terminal facilities. Exclusive of terminal facilities at the ports of entry, this improvement serves numerous wharves, some of which are open to the public on equal terms. These facilities are considered ample for existing commerce. Operations and results during fiscal year. Maintenance: Between July 24 and October 9, 1950, the contract dredge Hampton Roads removed 1,036,560 cubic yards of material from the main route of the waterway (Wilmington River, mile 578.5 to mile 583.4) at a cost of $106,064.18. Between May 7 and June 30, 1951 the contract dredge Savannah removed 475,510 cubic yards of material from the main route of the waterway (Jekyll Creek, mile 681.5 to mile 683.3) at a cost of $55,227.62. Plans and specifications for dredging contract in Jekyll Creek cost $1,050.55. Repairs to speed and directional markers cost $6,707.70. Miscellaneous surveys cost $5,780.44. The total cost for maintenance was $174,830.49. The expenditure was $140,852.08. Condition at end of fiscal year. The main 12-foot channel of the existing project was completed in 1941.
