Santee River, South Carolina.-This river was obstructed by sunken logs and snags. The bar was narrow, crooked, and shifting, with only about 4 feet depth at low tide. The project provides for leaving the Mosquito Creek Canal, which has been completed for about $100,000 as a lumber route, and for a new cut between Estherville and Minim Creek at an estimated cost of $250,000, and for completely snagging the Santee River itself at a cost of $100,000. During the past year the flood gate in the Mosquito Creek Canal was completed. Dredging on the new canal continued, and the rice drainage injured by this cut has been restored, as required by the right of way. Up to June 30, 1892, $113,340.51 has been spent in giving a passage 30 feet wide and 5 feet deep at high water from Santee River to Winyah Bay, in building a drawbridge over Mosquito Creek, and in replacing damaged rice drainage.

Wateree River, South Carolina.-This river had a low-water depth of from 3 to 4 feet from its mouth 67 miles to Camden. It was much obstructed by snags and by two railroad bridges without draws. The project provides for 4-foot steamboat navigation to Camden. Total expenditures to June 30, 1892, $53,177.23. The appropriation of September 19, 1890, completes the original estimated cost, and for this sum the river has been put into a satisfactory condition. The engineer in charge reports that an annual appropriation of $6,500 is needed for maintenance. This year's commerce amounts to 2,244 tons. July 1, 1891, balance unexpended...

Congaree River, South Carolina.—This river had a low-water depth of from 3 to 4 feet from its mouth 48 miles to the railroad bridge at Columbia, thence 1 foot low-water depth 2 miles farther. The lower 47 miles from Granby to the mouth was blocked by snags, and a railroad bridge without a draw. The 3 miles above Granby was impassable, being rapids. The project provides for 4-foot navigation below Granby and a cleared channel through the rapids above. The work of the year has been snagging. Twenty thousand dollars has been spent to June 30, 1892, giving 4-foot navigation to Granby. This year's commerce amounts to 3,686 tons. July 1, 1891, balance unexpended...

(See Appendix M 9.) 10. Charleston Harbor, South Carolina.-The work in progress since 1878 comprises two jetties of riprap with a mattress hearting wherever deemed advantageous, resting upon a mattress of logs and brush. The jetties spring from Sullivan and Morris islands and converge on curves so as to cross the bar on parallel lines about 2,900 feet apart. They are to establish and maintain a channel across the bar not less than 21 feet deep at low water, where heretofore the low-water depth has not exceeded 12 feet. Estimated cost for jetties up to low water $4,380,500; up to 3 feet above mean low water $5,334,500. Work continued under the contracts of Jacob Friday, and by hired labor. The contractor deposited 54, 686 tons of stone at a cost to the United States of $114,990.89; by hired labor 53,641 tons of stone were deposited at a cost to the United States of $91,420.60. The cost per ton by contract was 40 cents greater than by hired labor. Dredging began with the Government dredge, and 101,169 cubic yards of sand were removed between the 1st of August and the middle of February at a cost of 113 cents per yard. Dredging was then suspended to put in a larger boiler, and at the close of the fiscal year the vessel was about ready to sail from New York and resume work. No settlement of the jetties has occurred during the year. About 1 mile of the south jetty and three-fourths of a mile of the north jetty have been raised to high water during the year, and some work below water has been done. About 1,200 feet of breakwater has been built along the Mount Pleasant shore. The annual survey shows marked deepening between the jetties and for some distance beyond their outer ends with a narrow shoal crossed by a narrow crooked 12-foot break outside. There is now but a few hundred feet between 15 feet of water at low tide inside and out.

Ashley River, South Carolina.-The plan of improvement comprised the removal of a shoal about 8 miles above the city of Charleston, S. C., where there was only 9 feet of water at low tide, and another just below the Wando Phosphate Works where there was only 6 feet. Lowwater depths of from 10 to 11 feet with widths of from 100 feet to 200 feet have been obtained, and a balance is left for maintenance. This year's commerce amounts to 415,800 tons. Total expenditures to June 30, 1892, $4,673.66. July 1, 1891, balance unexpended (See Appendix M 11.) $826.34 826.34 12. Wappoo Cut, South Carolina.-The project provides for a channel 60 feet wide and 6 feet deep at low water between Ashley and Stono rivers. There is now a narrow 6-foot channel all the way through. This year's commerce amounts to 140,000 tons. Total expenditures to June 30, 1892, $40,416.77. Amount (estimated) required for completion of existing project.

Edisto River, South Carolina.-The river was much obstructed by snags and shoals. The project provides for a channel for rafts and flatboats from the sea, 260 miles, to Guignard Landing on the South Fork at an estimated cost of $33,385. The work of the year has been snagging. This year's commerce amounts to 132,580 tons. Total expenditures to June 30, 1892, $25,827.74. 14. Salkahatchie River, South Carolina.-The river was much obstructed by snags. The project provides for a continuous flatboat channel from 5 miles above Toby Bluff to Hickory Hill at an estimated cost of $18,000. This year's commerce has amounted to 13,300 tons. The last appropriation completes the estimated cost and no further funds will be required, the improvement being completed and a sufficient balance being left for maintenance.

Removing sunken vessels or craft obstructing or endangering navigation. Three wrecks in the upper branches of the Cooper River were examined in June, 1892, and their removal was authorized by the Secretary of War. (See Appendix M 16.) 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.

Savannah 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 estinated 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. |
