(See Appendix L 24.)

IMPROVEMENT OF LUMBER AND WACCAMAW RIVERS, NORTH CARO

LINA AND SOUTH CAROLINA, AND OF CERTAIN RIVERS AND HARBORS IN SOUTH CAROLINA.

Officer in charge, Capt. Frederic V. Abbot, Corps of Engineers; Division Engineer, Col. William P. Craighill, Corps of Engineers.

1. Waccamaw River to Waccamaw Lake, North Carolina and South Carolina.In 1880 this river was navigable for boats of 12 feet draft at all stages of water from Georgetown 23 miles to Bull Creek, and at high water 4 miles farther to Buck's lower mills; thence for boats of 7 feet draft at high water 22 miles farther to Conway; thence it possessed an obstructed channel for boats of 3 feet draft atordinary winter water 68 miles to Reeves Ferry; thence an obstructed channel with 3 feet depth at high water 30 miles to Lake Waccamaw.

The project provides for a chamel 12 feet deep at all stages of water and 80 feet bottom width from the mouth of the river to Conway; thence a cleared channel to Lake Waccamaw. The estimated cost is $138,400.

The work of the year has been snagging. Up to June 30, 1892, $77,900 has been spent, giving a thoroughly cleared channel with 100 feet least width, 7 feet deep at low water as far as Conway, and 40 feet width and 3 feet deep 68 miles above Conway.

The commerce of the past year passing over this river amounts to 83,103 tons. July 1, 1891, balance unexpended ..

2. Lumber River, North Carolina and South Carolina.—The river was obstructed by logs, snags, and overhanging trees, and in places by sand bars. It was crossed by a number of bridges without draws. The project contemplates the removal of snags, logs, overhanging trees, etc., for 70 miles below Lumberton, at an estimated cost of $35,000. The work of the year has been snagging. The bridges have been provided with draw spans or discontinued. The commerce of the year amounts to 6,800 tons. Total expenditures to June 30, 1892, $9,503.38. July 1, 1891, balance unexpended

3. Little Pedee River, South Carolina.—This river was much obstructed by snags and overbanging trees, and in places was subdivided into several branches. The project contemplates providing for steamboat navigation to Lumber River and pole-boat navigation to Little Rock. The estimated cost is $50,000. The work of the year has been snagging.

The project provides for thoroughly cleared 9-foot navigation 52 miles to Smith Mills, and 3}-foot navigation to Cheraw, 172 miles above the mouth, at all stages of water, at an estimated cost of $117,000. The work of the year has been snagging. This year's commerce amounts to 92,471 tons. Total expenditures to June 30, 1892, $75,642.61. July 1, 1891, balance unexpended...

The project provides for closing the northern mouth of Lynch River and snagging Clark River. The estimate cost is $7,500. The work of the year has been snagging. This year's commerce amounts to 6,586 tons. Total expenditures to June 30, 1892, $5,000. July 1, 1891, balance unexpended...

7. 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. This year's commerce amounts to 110,523 tons. July 1, 1891, balance unexpended ...

8. 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.

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....

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 114 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. Total
expenditures to June 30, 1892, $2,185,814.36.

11. 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

13. 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.
