EXAMINATIONS AND SURVEYS FOR IMPROVEMENT, TO COMPLY WITH REQUIREMENTS OF THE RIVER AND HARBOR ACT OF AUGUST 11, 1888. The act of August 11, 1888, provides for examination and survey of Savannah River, as to whether the damage to the Vernezobia freshet bank in eighteen hundred and eighty-seven was caused by the work at Cross Tides, and whether the maintenance of said bank is essential to the success of the work at Cross Tides, and what will be the cost of so constructing said bank as to confine the water of said river to its bed. Lieutenant Carter was charged with and has completed this examination and survey, the results of which will be found in Appendix O 11. It appearing from the report of the preliminary examination made by the local engineer that the following localities are worthy of improvement, and the public necessity therefor being apparent from the facts and reasons reported, which are concurred in by the Chief of Engineers, Lieutenant Carter was charged with their survey, the results of which will be submitted when received: 1. Savannah River above Augusta, and between Augusta and Andersonville, Georgia. 2. Oconee River, Georgia. 3. Ocmulgee River, Georgia. IMPROVEMENT OF CERTAIN RIVERS AND HARBORS IN THE STATE OF FLORIDA. Officer in charge, Capt. William M. Black, Corps of Engineers, with Lieut. D. Du B. Gaillard, Corps of Engineers, under his immediate orders; Division Engineer, Col. William P. Craighill, Corps of Engineers. 1. St. John's River, Florida.-Operations for the improvement of this river have been carried on in conformity with a project submitted in 1879 by the late General Gillmore, colonel Corps of Engineers. The plan contemplates the formation of a continuous channel 15 feet deep at mean low water from Jacksonville to the ocean. The points where work is required are in a reach near Dame's Point, 12 miles from the mouth, and on the bar at the mouth. Near Dame's Point the mean low-water depth varies from 9 to 10 feet. The bar at the mouth is formed of sand. Before work began, the mean low-water channel depth across it varied from 5 to 7 feet, with a tidal range of 5 feet. The channel across the bar shifts continually north and south through a mile range. The work was divided in two parts, (1) the formation of a channel across the bar at the mouth, by the concentration and direction of the tidal currents by two jetties, to start from the opposite shores of the entrance, and to converge until, on the bar, their outer ends should be approximately parallel and 1,600 feet apart; and, (2) the improvement of the Dame's Point Reach. The estimated cost of the two parts is $1,306,500 and $120,000, respectively. As the improvement at the mouth was at first most urgently required, the five appropriations up to that of 1886, inclusive, aggregating $675,000, were made for improving "the channel over the bar at the mouth," under the estimate for that part of the total project. Since 1887 the depth on the bar has been greater than that in the Dame's Point Reach, and the interests of commerce have demanded that work at the latter point should be started. Accordingly, the appropriation in the act of August 11, 1888, was made for improving the river "from Jacksonville to the ocean, including the channel over the bar at the mouth," under the estimate for the entire project, of which $576,500 remains to be appropriated. On June 30, 1888, the south jetty had a total length of 6,667 feet, of which 4,100 feet were built to the level of mean low water. The north jetty had a total length of 6,585 feet, of which a length of 553 feet, including the shore extension, was at the full height and capped. With this exception, neither jetty has been built a full-sized cross-section. Both jetties are made of one or more layers of log or brush mattresses covered with riprap stone. Since 1886 oyster shells have been used as hearting. The total proposed lengths for the south and north jetties. are 6,800 and 9,400 feet, respectively. The amount expended to June 30, 1888, was $670,957.13. At that time a straight permanent channel had been secured across the bar, having a least mean low-water depth of from 12 to 13 feet. The channel depth across the bulkhead at the inner end of the jetties was from 11 to 12 feet. Operations during the fiscal year ending June 30, 1889, comprised a survey of the Dame's Point Reach, on which to base a detailed project for its improvement, and the continuation of the work on the north jetty, under the contract with Mr. R. G. Ross, of Wilmington, N. C.; the foundation of the north jetty was extended 1,455.2 feet by brush fascine mattresses 120 feet wide, ballasted with stone, the narrow portion of the superstructure was strengthened and built up, and it was ex |
