IMPROVEMENT OF CERTAIN RIVERS AND HARBORS IN GEORGIA, AND

OF CUMBERLAND SOUND, GEORGIA AND FLORIDA.

Officer in charge, Capt. O. M. Carter, Corps of Engineers, with Lieut. Thomas H. Rees, Corps of Engineers, under his immediate orders; Division Engineer, Col. Wm. P. Craighill, Corps of Engineers.

1. Savannah Harbor, Georgia.—The plan of improvement under which operations have been carried on in Savannah Harbor during the last fiscal year was approved by the Secretary of War on July 22, 1890. The project contemplates the establishment of a navigable channel 26 feet deep at mean high water between the city of Savannah and Tybee Roads. The mean rise and fall of tides varies from about 7 feet at Fort Pulaski to about 6 feet in front of the city wharves.

The estimated cost of the improvement is $3,500,000.

In 1873, prior to improvement, the channel was in places not more than 9 feet deep at mean low water, and the usual high-water draft of vessels was not more than 14.5 feet.

Prior to July 1, 1891, there had been placed in the work, under the present project, 72,178.84 square yards of log and brush mattresses, 27,294.82 cubic yards of stone, 2,339 piles, and 25,825.57 cubic yards of brush fascines; and there had been removed from the channel, by dredg. ing, 396,144.66 cubic yards of material.

During the fiscal year just closed 683.77 cubic yards of stone has been used in the oyster bed training wall. In the pile and brush work, forming the training walls below Spirit Island and the spur dams protecting the banks at Elba Island and Jones Island there have been used 934 piles, 28,969.01 cubic yards of brush fascines, and 1,604.46 cubic yards of stone. There were also driven 44 clusters of piles at the ends of the Jones Island and Elba Island spur dams.

Between the Ocean Steamship Company's wharves and Tybee Knoll 36,170.5 cubic yards of material have been removed by dredging. The expenditures during the year amounted to $133,322.39.

The total amount expended under the present project to June 30, 1892, including all outstanding liabilities, is $346,377.80.

There is now a navigable channel from the city to the sea with a least mean low-water depth of 14 feet, a gain of about 5 feet since the work was begun.

The real gain in navigable depth is somewhat greater than here shown, and vessels of from 20 to 21 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 25 years. July 1, 1891, balance unexpended ..

2. Sarannah River, Georgia.-The present project for the improvement of this river was adopted in 1890, the object being to secure a low-water 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, 1891, including all outstanding liabilities, was $7,411.24, 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.

The expenditures during the year ending June 30, 1892, including all outstanding liabilities, amounted to $16,665.51.

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 the work 4,861.40 cubic yards of brush fascines and 3,352.47 cubic yards of stone. The increased depth of water over the shoals near Augusta has been maintained.

3. 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 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, during which the total amount expended, including all outstanding liabilities, was $4,870.49, resulting in the removal of 13,194.6 cubic yards of material from the worst shoal in the harbor.

The expenditures during the fiscal year just closed, including all outstanding liabilities, amounted to $22,431.21, and resulted in the removal by dredging of 73,445.6 cubic yards of material from the most troublesome shoals. July 1, 1891, balance unexpended....

4. 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 depth at some points not exceeding 2 feet.

The total amount expended under the present project to June 30, 1891, including all outstanding liabilities, was $2,146.79, and resulted in removing many of the most dangerous snags and overhanging trees. Five hundred and twenty-one snags and 1,011 overhanging trees were

ENG 92-12

removed during the fiscal year 1892, 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. July 1, 1891, balance unexpended .

5. 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. Under the present project, prior to July 1, 1891, 1,135 logs, snags, and stumps, and 146 overhanging trees were removed; 600 cubic yards of stone was placed in a closing dam at Fish Trap Cut; 19 piles were driven, and 11 brush mats sunk at Old Boat Yard, in constructing contracting works at that point.

The total amount expended under the present project to June 30, 1891, including all outstanding liabilities, was $8,120.31, and resulted in so improving the river that boats now run at a stage of water 4 feet lower than before improvements were begun.

During the fiscal year just closed the expenditures, including all outstanding liabilities, amounted to $14,283.30. There were removed from the channel 571 snags and stumps, 16,658 overhanging trees, and 366.5 cords of drift; 116 trees were girdled, and 166 logs were cut up.

In building spur dams at Old Boat Yard 13 snags and stumps were removed, 661 linear feet of brush mattresses was sunk, 146 piles were driven, and 935 linear feet of piling was wattled with poles. A new snagboat, the Satilla, was completed October 3, 1891. July 1, 1891, balance unexpended ...

6. 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.

During the fiscal year just closed the expenditures, including all outstanding liabilities, amounted to $15,629.88. 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. July 1, 1891, balance unexpended..

The project contemplates the establishment of a navigable channel not less than 15 feet deep at mean low water. The mean rise and fall of tide is 6,8 feet.

The cost of the project of 1880 was estimated at $73,187.50, and as enlarged in 1886 at $190,000, inclusive of appropriations already made.

In 1880, prior to improvement, the channel was not more than 9 feet deep at mean low water.

During the fiscal year just closed there was removed from the channel by dredging 49,324,3 cubie yards of material.

The amount expended to June 30, 1892, including all outstanding liabilities, is $161,694.86, and has resulted in securing a navigable lowwater channel not less than 13.6 feet deep. July 1, 1891, balance unexpended
