(See Appendix N 3.) 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. During the fiscal year just closed 150 snags, stumps, and logs, and 466 overhanging trees were removed; 4 trees were pulled back, and 2 logs were cut up on bank. The expenditures during the year amounted to $1,946.79. The total amount expended under the present project to June 30, 1891, including all outstanding liabilities, is $2,446.79, and has resulted in removing many of the most dangerous snags and overhanging trees.

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. During the fiscal year just closed 1,135 logs, snags, and stumps, and 146 overhanging trees were removed, 600 cubic yards of stone were placed in a closing dam at Fish Trap Cut, and 19 piles were driven and 11 brush mats sunk at Old Boat Yard in constructing contracting works at that point. The expenditures during the year amounted to $8,120.31. The total amount expended under the present project to June 30, 1891, including all outstanding liabilities, is $8,120.31, and has resulted in so improv ing the river that boats now run at a stage of water 4 feet lower than before improvements were begun.

Removing sunken vessels or craft obstructing or endangering navigation. The wrecks of the steamers Habersham and General Lee, together with some other vessels and barges sunk during the revolutionary and civil wars, were, after due advertisement, removed by contract during the year. (See Appendix N 10.) EXAMINATIONS AND SURVEYS FOR IMPROVEMENT, TO COMPLY WITH REQUIREMENTS OF RIVER AND HARBOR ACT APPROVED SEPTEMBER 19, 1890. The required preliminary examination of Yellow River, Georgia, from the railroad bridge near Covington to the Ocmulgee, with a view of obtain ing a steamboat channel of 5 feet deep at mean low water, was made by the local engineer in charge, Captain Carter, and report thereon submitted through Col. Wm. P. Craighill, Corps of Engineers, Division Engineer, Southeast Division. It is the opinion of Captain Carter, and of the Division Engineer, based upon the facts and reasons given, that this locality is not worthy of improvement. This opinion being concurred in by me, no further survey was ordered. (See Appendix N 11.) The required preliminary examinations of the following localities were made by the local engineer in charge, Captain Carter, and reports thereon submitted through Col. Wm. P. Craighill, Corps of Engineers, Division Engineer, Southeast Division. It is the opinion of Captain Carter, and of the Division Engineer, based upon the facts and reasons given, that these localities are worthy of improvement. The conclusions of these officers being concurred in by me, Captain Carter was charged with their survey, the reports on which will be submitted when received. 1. The inside route between Savannah, Georgia, and Fernandina, Florida, with a view of obtaining a steamboat channel of 7 feet depth at mean low water. 2. The inside route between Doboy and Sopelo [Sapelo], Georgia, with a view of making the same navigable for sea-going vessels. 3. Brunswick Outer Bar, Georgia, to determine the feasibility and cost of deepening the same to 26 feet at ordinary high water. IMPROVEMENT OF CERTAIN RIVERS AND HARBORS IN FLORIDA. Officer in charge, Capt. W. M. Black, Corps of Engineers, with Lieut. D. DuB. Gaillard, Corps of Engineers, under his immediate orders; Division Engineer, Col. Wm. 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 Gilmore, 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 Point, 12 miles from the mouth, and on the bar at the mouth. Near Dame Point the mean lowwater depth varies from 12 to 13 feet, with a tidal range of 1 to 2 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 5.8 feet. The channel across the bar shifted continuously north and south through a mile range. The work was divided into 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 Point Reach, by dredging, and the construction of works of protection, under a project approved June 11, 1891. As the improvement at the mouth was at first most urgently needed, 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 Point Reach, and the interests of commerce have demanded that work at the latter point should be started. Accordingly, the appropriations since 1888 were 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. At the close of the fiscal year 1889-'90, $828,065.21 had been expended. The south jetty had a total length of 7,147 feet. Of this 1,740 were at the full height and capped; 2,740 were built to the height of mean low water, but with insufficient width of crest; for 800 feet further the average low-water depth on the crest was 1 foot; for the remaining distance the jetty crest was about 5 feet below mean low water. The total length of the north jetty was 9,048 feet. Of this 553 feet were built to full height and capped; 6,404 feet were built up to mean low water, with insufficient width of crest; the mean low-water depth over the remaining length averaged 1 to 5 feet. Prior to 1886 the jetties were built of alternate layers of mattresses and rock. Since |
