A contract was entered into with P. Sanford Ross, of Jersey City, N. J., for all of the dredging and with the Atlantic Contracting Company, of New York, for all of the other work required for the improve ment. During the fiscal year just closed there were used in the pile and brush work forming the training walls below Spirit Island, the spurdams protecting the banks at Elba and Jones Island, and the Duck Puddle closing dam, 62,859.47 cubic yards of brush fascines; 66,186.93 square yards of brush mattresses; 2,972.75 cubic yards of riprap stone; 302,027.60 feet, B. M., of 6 by 10 inch timber, as waling, cross and back ties, and 33,399.1 pounds of iron bolts for fastening the timber to the pile work; there were driven 2,571 piles, 268 groups of tie piles, and 7 clusters of fender piles, making a total of 3,128 piles. There were put into the lower-flats training wall 829.18 cubic yards of fascines, 174,522.02 square yards of brush mattresses, and 5,082.34 cubic yards of riprap stone. Between the Ocean Steamship Company's wharves and Tybee Knoll 488,518.68 cubic yards of material has been removed by dredging. The total amount expended under the present project to June 30, 1893, including all outstanding liabilities, is $827,669.48. There is now a navigable channel from the city to the sea with a mean low-water depth of 15.5 feet, a gain of about 6.5 feet since the the work was begun. The real gain in navigable depth is somewhat greater than here shown, and vessels of from 21 to 22 feet draft now go from the city to the sea on a single tide. The estimated reduction in freight rates, due to the improvements already executed, is 25 per cent, which effects an annual saving in freights alone of more than the total sum of money expended by the United States upon the harbor within the last twenty-five years.

Savannah River, Georgia.-The present project for the improvement of this river was adopted in 1890, the object being to secure a lowwater steamboat channel not less than 5 feet in depth between the cities of Augusta and Savannah, Ga. The estimated cost of the improvement is $332,000. Prior to improvement navigation was much impeded by logs, snags, piles, and other obstructions. The depth at summer low water over some of the shoals did not exceed 2 or 3 feet. The total amount expended under the present project to June 30, 1892, including all outstanding liabilities, was $24,076.75, and resulted in removing 354 snags, stumps, and logs, and 3,443 overhanging trees from the most troublesome places throughout the whole extent of the river. Five trees were swung to bank, and 24 logs were cut up on bank. Seven spur-dams were constructed for the protection of caving banks below the city of Augusta, and some of the old dams were repaired. There were placed in this work 4,861.40 cubic yards of brush fascines, and 3,352.47 cubic yards of stone. The expenditures during the year ending June 30, 1893, including all outstanding liabilities, amounted to $10,028.60. There have been removed from the river during the present fiscal year 2,619 snags and stumps; 8,495 overhanging trees and projecting logs were cut and removed from the banks. 272,000.00 Amount (estimated) required for completion of existing project................

(See Appendix N 2.) 3. Savannah River above Augusta, Ga.-The present project for the improvement of this part of Savannah River is outlined in report of Capt. O. M. Carter, Corps of Engineers, dated January 31, 1890, and adopted in 1892. It contemplates the establishment of a pole-boat channel between Petersburg, Ga., and the Locks, above Augusta, Ga., 12 to 25 feet wide and navigable at ordinary summer low water for boats drawing 2 feet. This is to be accomplished by the removal of sand shoals, ledges of rock or gravel, and overhanging trees, and by the construction of spur dams and training walls to maintain the depth of the improved channel. The estimated cost of the improvement is $33,000. Prior to July 1, 1892, there was no work done under the present project. During the fiscal year just closed there were new dams built, old ones repaired and extended, and rock excavated from the channel at the following places: Stevens Creek Falls, Half Way Ledge, Four Mile Reach, Pine Log Shoals, Scotts Shoal, and Chicken Sluice. There were used in this work 2,018.66 cubic yards of fascines, 1,186.30 cubic yards of riprap stone, and 200 pounds of explosives. There was excavated from the channel 341.5 cubic yards of rock, and the river banks were cleared from The Locks, above Augusta, Ga., to Petersburg, Ga., a distance of 48 miles. (Amount (estimated) required for completion of existing project.

Darien Harbor, Georgia.-The plan of improvement under which operations have been carried on in Darien Harbor during the last fiscal year was adopted in 1885. The project contemplates the establishment of a navigable channel 12 feet deep at mean low water between Darien and Doboy. The mean rise and fall of this tide is about 6.5 feet. The estimated cost of the improvement is $170,000. No work was ever done under the existing project prior to the fiscal year ending June 30, 1891. The total amount expended under the present project to June 30, 1891, including all outstanding liabilities, is $24,321.97. During the fiscal year just closed there were constructed 20 spur dams for the improvement of the upper river, in the construction of which there have been used 15,068.35 cubic yards of brush fascines, 59,290.25 feet, B. M., of 6 by 10 inch timber, and 6,094.46 pounds of iron bolts. There were driven 1,075 piles, 4 groups of tie piles, and 39 clusters of fender piles, making a total of 1,200 piles. The total expenditures under the present project of improvement to June 30, 1893, including all outstanding liabilities, amounted to $49,546 68.

Altamaha River, Georgia.-The plan of improvement under which operations have been carried on upon the Altamaha River during the last fiscal year was adopted in 1890. The project contemplates the establishment of a steamboat channel 3 feet in depth at ordinary summer low water between Darien and the junction of the Oconee and Ocmulgee rivers. The estimated cost of the improvement is $129,000. Prior to improvement navigation was much impeded by logs, snags, and other obstructions, the low-water depths at some points not exceeding 2 feet. The total amount expended under the present project to June 30, 1891, including all outstanding liabilities, was $2,446,79, and resulted ENG 93-13 in removing many of the most dangerous snags and overhanging trees. Since then and up to June 30, 1892, there were removed 521 snags and 1,011 overhanging trees, and 8 logs were cut up. At Beards Bluff 1,231 linear feet of wattled-pile spur dams were constructed and the old training wall was repaired. The total expenditures under the present project up to June 30, 1892, including all outstanding liabilities, amounted to $8,369.11. During the fiscal year just closed there were constructed at Couper Bar a training wall and 3 spur dams, aggregating 932 feet in length, in the construction of which there were used 4,390.11 cubic yards of brush fascines, 141.51 cubic yards of riprap stone, 12,502.25 feet, B. M., of 6 by 10 inch timber, as waling, cross and back ties, and 1,285.40 pounds of iron bolts for fastening the timber to the pile work.

Oconee River, Georgia.-The plan of improvement under which operations have been carried on upon the Oconee River during the last fiscal year was adopted in 1890. The project contemplates the establishment of a steamboat channel 3 feet in depth at ordinary summer low water between Milledgeville and the mouth of the river. The estimated cost of the improvement is $171,000. Prior to improvement navigation was much impeded by sand bars, overhanging trees, snags, and sunken logs. On some shoals there were low-water depths of not more than 2 feet. Prior to July 1, 1892, there were removed under the present project 1,719 logs, snags and stumps, 16,804 overhanging trees, and 366.5 cords of drift; 116 trees were girdled and 166 logs were cut up; there was placed in the closing dam at Fish Trap Cut 600 cubic yards of stone. In building spur dams at Old Boat Yard there were driven 165 piles; 935 linear feet of piling was wattled with poles, and 991 linear feet of brush mattresses, 18 feet wide, was sunk. A new snag boat, the Satilla, was completed October 3, 1891. The total amount expended under the present project to June 30, 1892, including all outstanding liabilities, is $22,403.61. During the fiscal year just closed there have been removed from the channel 1,588 snags and stumps, 81 overhanging trees, and 61 logs were cut up on the river bank, which work has resulted in putting the channel from the Central Railroad bridge to 113 miles above it in a good, navigable condition.

(See Appendix N 6.) 7. Ocmulgee River, Georgia.-The plan of improvement under which operations have been carried on upon the Ocmulgee River during the last fiscal year was adopted in 1890. The project contemplates the establishment of a steamboat channel 3 feet in depth at ordinary summer low water between Macon and the mouth of the river. The estimated cost of the improvement is $210,000. Prior to improvement navigation was much impeded by rock shoals, sand bars, overhanging trees, snags, and sunken logs, the low-water depth at some places not exceeding 2 feet. The total amount expended prior to June 30, 1891, including all outstanding liabilities, was $13,099.69, and resulted in removing many dangerous obstructions, boats now being able to run without accident at a stage of water some 3 feet lower than before the improvements were begun. Since then and up to June 30, 1892, there were removed from the river 2,912 snags and stumps and 6,756 overhanging trees; 19 trees were girdled and 66 logs were cut up on the bank. The total amount expended under the present project up to June 30, 1892, including all outstanding liabilities, is $28,205.77. During the fiscal year just closed the works at Tillmans Bar were thoroughly repaired, and one new spur dam, as well as 278 linear feet of bank protection, was built at this place. In this work there were driven 124 piles, and there were used 1,163 cubic yards of brush mattresses, 1,112 cubic yards of riprap stone, 2,085 poles, 20 feet by 3 inches, for wattling, 94,332 feet, B. M., 12 by 12 inch timber, and 2,500 pounds of iron spikes. There was also excavated 1,080 cubic yards of material for the construction of the shore protection. The work done during the fiscal year has resulted in putting the channel from the mouth to Macon in good condition and in giving a least depth of 4.7 feet across Tillmans Bar. |
