San Luis Obispo Harbor, California.-The project for this improvement is intended to secure a protected anchorage and landing at Port Harford by the construction of a breakwater on Whaler Reef extending from Point San Luis to Whaler Island, and thence to a point where the outer reef rises above high water. The total length of the structure when completed will be about 2,300 feet. That portion of the breakwater between Point San Luis and Whaler Island is completed, and a commencement has been made upon the extension beyond the island. A contract was entered into January 20 last with the San Francisco Bridge Company to deliver and place in position upon the outer reef about 11,000 tons of rock. The Light House Board having granted permission to take material from the reservation at Morro Rock, the contractor is engaged in running a tunnel so that all the material required to fill the contract can be blasted at one time. The work of depositing the material in place upon the line of the breakwater will be commenced in July, and the work contracted for will be completed before December. Work will be continued in the future upon the other extension of the breakwater. The amount of $125,000 asked for the fiscal year ending June 30, 1893, is for a continuance of these operations. The total amount appropriated for the improvement is $65,000, and the total amount expended is $25,917.44.

(See Appendix U U 4.) 5. Wilmington Harbor, California.-Previous to the commencement of the improvement in 1871 there was a depth not to exceed 1 foot at the entrance at low tide. In 1881 this depth had been increased to 10 feet. The present project, which was adopted on that year, is intended to secure a depth of 16 feet at mean low water. That depth has been obtained through the channel from the railroad wharf to Deadman Island. In the channel along the island, and at the entrance, the least depth is 13.5 feet a gain of 1.5 feet during the last year. It is intended to still increase this depth by dredging and by extending the jetties. During the past year, operations have consisted in making needed repairs to the timber work of the east jetty; dredging a channel 300 feet wide to a depth of 16 feet at mean low water from the railroad wharf to Deadman Island, and in raising and extending the jetties. Sixty-two thousand two hundred and ninety-five and forty-six hundreths cubic yards of material were dredged from the inner channel, and deposited in San Pedro Bay. Contracts were entered into for the delivery of 33,000 tons of rock for the jetties. At the close of the year the contractors had delivered 15,123.47 tons of material, which was used in building up the west jetty to its full height at various points and upon its extension seaward. The work of dredging and of jetty extension will be carried on during the coming season, and in the future under the existing project to the extent of the funds made available. The amount estimated to complete existing project is $51,000. The total appropriated is. The total expended is July 1, 1890, balance unexpended.......

San Diego Harbor, California.-The work heretofore carried on at San Diego had for its object the preservation of the harbor which was being injured by the deposition of material brought down by the San Diego River in flood stages. The river was diverted from its course and caused to empty into False Bay. This was accomplished by building a substantial levee across the old channel of the river near its entrance to the harbor and excavating a new water way leading to False Bay. This work was completed in 1876, since which time operations have consisted simply in keeping the levee in good condition. The total amount expended upon the work to the close of the fiscal year, including a small amount from the present appropriation, is $82,085.37. The dredging at the head of the middle ground, so as to provide a channel at that point 500 feet wide and 24 feet deep at mean low water, was commenced in April. At the close of the fiscal year 4,220 cubic yards of sand had been dredged, providing a channel 150 feet wide. Dredging will be continued to the extent of the available funds. It is expected that the channel will be completed by the end of August. The approved, project for securing a depth of 26 feet at mean low tide over the bar contemplates the construction of a jetty of brush and stone 7,500 feet in length, extending from the south shore of Coronado North Island out on Zuninga Shoals. Before commencing operations the title to the land at the root of the jetty must be acquired by the United States. As the parties owning the land have declined to sell the tract desired, condemnation proceedings will be undertaken to secure the tract for the Government. When this is accomplished the construction of the jetty will be commenced. The amount appropriated for dredging is $8,000 and the amount expended, including outstanding liabilities, is $1,967.47. The amount appropriated for jetty on Zuninga Shoal is $52,000, and the amount expended is $85.00. The amount asked for the fiscal year ending June 30, 1893, is for a continuance of work upon the jetty and for the care of the levee at Old Town. July 1, 1890, balance unexpended.....

(See Appendix U U 6.) EXAMINATIONS FOR IMPROVEMENT, TO COMPLY WITH REQUIREMENTS OF RIVER AND HARBOR ACT APPROVED SEPTEMBER 19, 1890. The required preliminary examinations of the following localities were made by the local engineer in charge, Lieutenant-Colonel Benyaurd, and reports thereon submitted. It is the opinion of LieutenantColonel Benyaurd, based upon the facts and reasons given, that these localities are not worthy of improvement. This opinion being concurred in by me, no further surveys were ordered. 1. San Rafael River, California.-Report transmitted to Congress, and printed as House Ex. Doc.

Benyuard, Corps of Engineers, was constituted "to examine the Pacific coast between Points Duma and Capistrano with a view to determining the best location for a deep-water harbor," and to report a project and estimate of cost for the same. The report of the Board will be submitted when received. IMPROVEMEMT OF SAN JOAQUIN, MOKELUMNE, SACRAMENTO AND FEATHER RIVERS, PETALUMA CREEK, AND HUMBOLDT HARBOR AND BAY, CALIFORNIA. Officer in charge, Maj. W. H. Heuer, Corps of Engineers; Division Engineer, Col. G. H. Mendell, Corps of Engineers. 1. San Joaquin River, California.-This river before improvement began had a 6-feet deep low-water channel less than 100 feet wide to Stockton, and a channel less than 2 feet in depth, for a few months annually, on the upper river to Hill's Ferry. The project adopted in 1877 had for its object the securing and maintaining, by dredging, of a channel 100 feet wide and 9 feet deep to Stockton, and the making of cut-offs, and the general temporary im provement of the upper river by wing dams, snagging, and the partial or complete closure of some of the outlets. The project as adopted has been carried on continuously whenever funds permitted, and as a result the time of annual navigation on the upper reaches of the river has been prolonged, and a 9-foot channel maintained to Stockton by dredging. Without this annual dredging navigation to Stockton would soon be closed, as the channel in Stockton Slough is not and can not be made self maintaining. At the close of the last fiscal year the river was so high that its real condition could not be ascertained, but it was believed that the unusual floods had refilled the Stockton Channel to a great extent, and also carried away a considerable portion of the submerged dam at Paradise Cut. This was found to be true, and from the middle of October, 1890, to the middle of May, 1891, dredging was carried on continuously, Stockton Slough being again dredged to a 9-foot depth at low water, and two sand bars being removed from the main river. This enabled navigation to Stockton to be carried on uninterruptedly the whole year. This dredging required the removal of 138,242 cubic yards of material in cuts aggregating 16,374 feet long, each cut being made 50 feet wide. This work was done at an average cost of 10 cents per cubic yard. During May and June, 1891, contracts were made to rebuild the dam at Paradise Cut, which was destroyed by the excessive floods of the spring of 1890, and build a dam at Laird Slough. A contract has also been let to make a cut-off at Head Reach. At the end of the fiscal year operations were being commenced on all three of these works. Up to the end of the fiscal year ending June 30, 1890, $180,330.49 had been spent on this river; during the present fiscal year an additional $15,490.01 has been spent. The expenditure of this money, has enabled navigation to Stockton to be carried on continuously without interruption or delay. The navigation of this river is carried on 10 steamboats, the largest having a gross tonnage of 880 tons, and 14 barges with an average tonnage of 300 tons. Dredging will be again required in Stockton Slough to maintain navigation, and snagging and wing-dam building or small cut-offs may be required in the upper river. The cut at Head Reach will require to be enlarged and another cut-off should be made at Twenty-one Mile Slough. All this can be done in one fiscal year. As owners of land where cut-off was to be made demanded an exorbitant price for it, which we did not pay, the navigation company and a few public-spirited citizens bought the right of way over the proposed line of cut and deeded it free of expense to the Government. Should any money be appropriated for making the cut-off at Twenty-one Mile Slough, it is recommended that it be with the proviso that none of the money for making the cut-off shall be expended until the right of way on the line of the cut-off shall be deeded to the United States Government free of expense.

Mokelumne River, California.-Before improvement began on this river in 1884 it was obstructed by snags and overhanging trees, causing delay and danger to navigation, and the project adopted aimed at the removal of these obstacles. There has been appropriated $13,000, of which $12,457.62 has been spent, and in 1884, 1885, 1886, 1887, and 1888 all obstructions were removed and the project completed leaving the river in good navigable condition. No work has been done in the last fiscal year, but au examination was made which showed obstructions in the shape of a sharp point of land and a shoal caused by a drainage canal, dug by private parties, which are a great and increas ing injury to the navigation of the river. Snags will also again lodge in the river and overhanging trees will again require removal. To remove these obstructions and again clear the river of trees and snags it is estimated will cost $9,100. It is not believed that the improvements have caused any reduction in the rates of freight or insurance, but the rate of freight by steamer is $1 less than by rail from compet ing points, thus effecting a large saving in freight annually. One steamer, the Constance, makes three round trips and carries all the freight offering. July 1, 1890, balance unexpended June 30, 1891, amount expended during fiscal year..
