taken by the current of the river after it leaves the end of the present south pier, about north, 78° west, from the present west end of that pier. To permanently improve the harbor the south pier should be extended for a distance of 928 feet in this direction, and a north pier should be built parallel to it for a length of 940 feet. These two piers, it is estimated, would cost $116, 666.

Wharton, corps of engi neers. 1. Improvement of St. Mary's River, Michigan.-During the past fiscal year the work for the improvement of the navigation of this river has been confined entirely to dredging in the middle channel of Lake George, in accordance with the original plan of making a channel 200 feet wide and 14 feet deep. It is expected that at the close of the present working season this work will be completed and the contract closed. The officer in charge reports that during the fiscal year there were excavated and removed 76,342 cubic yards of clay and sand. Amount expended on the work during the fiscal year ending June 30, 1869.. Amount available July 1 for continuing the work........ $38,053 10 14, 799 47 Special surveys have been made of other points in the St. Mary's River where improvements are required. The officer in charge estimates that to increase the channel to the necessary width and depth at these several localities will cost as follows: Amount required annually to keep the improvements in good condition, when completed.. Amount that could profitably be expended during the next fiscal year.... (See Appendix C.) 19,570 00 3,000 00 3,000 00 141, 021 00 $10,000 00 60, 000 00 2. Improving mouth of Au Sable River, Michigan, Lake Huron.-During the working season of 1868, thirty cribs were constructed and placed in position in line of piering. At the close of the season there were 240 linear feet of crib-work on the north side and 660 feet on the south. At the opening of the present season, damages caused by the gales and ice of the winter were repaired. Amount available July 1, 1868. Amount available July 1, 1869... $45, 502 38 31, 794 46 13, 707 92 The officer in charge reports that during the present working season he expected to extend the north pier by two cribs and the south by three cribs; to fill a breach made in the south pier with two cribs, and to complete the filling and superstructure on both lines of piers. Amount required to complete the improvement according to original design.. Annual amount required to keep this harbor open after completion of work.... (See Appendix C.) $20,000 00 3,000 00 3. Improvement of mouth of Saginaw River, Michigan, Lake Huron.— This work was completed on the 9th October, 1868, to the full extent contracted for. Dredging has been done throughout a length of 6,800 feet, giving a channel of 195 feet in width and 12 feet in depth "below the low stage during the calm weather of navigation." Amount available July 1, 1868...... Amount allotted from general appropriation of 1868... $28, 149 29 9,000 00 37, 149 29 Amount expended during fiscal year, $36,043 54, leaving a small balance available for contingencies. The engineer in charge estimates that $1,500 will be required annually to keep the channel in good condition. (See Appendix C.) 4. St. Clair Flats, Lake St. Clair.-The total length of the proposed canal is about 8,200 feet; width between dikes, 300 feet; depth of water, 13 feet-below lowest stage known during navigation. Up to the close of the last fiscal year, June 30, 1869, there had been dredged about 4,320 linear feet of the canal bed to the full width and depth-the earth being placed in the banks-and about 7,028 linear feet of dike revetments and banks have been constructed. Amount available from specific appropriation of 1866 and 1867, on July 1, 1868. Allotment from appropriation of 1868... $214, 427 28 86, 000 00 Allotment from appropriation of 1869..

(See Appendix C.) HARBORS ON LAKE ERIE, WEST OF DUNKIRK. Officer in charge, Major Walter McFarland, corps of engineers. 1. Monroe Harbor, Michigan.-Nothing has been done here; though since the close of the year the work of dredging the bar and protecting the north pier has been let, to be completed probably by the beginning of winter. Balance June 30, 1868... Expended during the fiscal year. On hand July 1, 1869.. No further appropriation is asked. (See Appendix D.) $10,590 21 178 73 10, 411 48 2. Harbor of Toledo, Maumee Bay, Ohio.-Nineteen thousand one hundred cubic yards of sand were removed from the channel. The project of a straight ship canal through Maumee Bay, which was submitted by General Cram, was referred by me to a board of engineers, which recommended in its stead the improvement of the western channel by dredging. The recommendation of the board was approved by me, and the reports were submitted to the Secretary of War, and by him transmitted to Congress. Since the termination of the year an allotment of $30,000 has been made for dredging the western channel, which will be expended by the close of navigation. To put this channel in condition suitable to the magnitude of the commerce of Toledo and its rapid growth, there will be required, in addition, $120,000. 3. Sandusky River, Ohio.-The operations of the year have consisted in cutting channels sixty feet wide and eight feet deep through the first shoal place below Whitacie Bar, through the bar off Squaw Island, and the bar at the mouth of the river-removing altogether 27,353 cubic yards of material. Balance June 30, 1868. Expended during the fiscal year.. On hand July 1, 1869..... $8,340 21 7,990 77 349 44 There could be profitably expended in improving these channels in the coming year, $20,000. (See Appendix D 3.) 4. Sandusky City Harbor, Ohio.-The channel over the outer bar has been widened to two hundred and forty feet during the year, and deepened to twelve feet, excepting in two places where the depth is eleven feet six inches. The balance of the appropriation is to be applied to the improvement of the channel over the inner bar. To make this channel two hundred and fifty feet wide an additional appropriation of ten thousand dollars is needed. Balance June 30, 1868.. On hand July 1, 1869.... $24,353 76 13,988 70 10,365 06 All of which will be expended during the present season in deepening the channel over the inner bar. Required for the next fiscal year, $10,000. (See Appendix D 4.) 5. Huron Harbor, Ohio.-Nothing has been done in the improvement of this harbor during the past fiscal year. Since its close, however, estimates of the cost of necessary repairs in both piers have been made, advertised, and the work let, to be completed this fall. Balance on hand June 30, 1868... Expended during the fiscal year.. $13,774 31 200 95 To be applied to further repairs as the necessity for them arises, which will not probably amount to more than $1,500 per year. No further appropriation is asked. (See Appendix D 5.) 6. Vermillion Harbor, Ohio.-Nothing has been done since the close of the last fiscal year, the piers being in very good condition, and giving no indications of needing further repairs very soon. The appropriations and allotments for this work are exhausted. Probable annual cost of keeping the piers in repair, $1,000. (See Appendix D 6.) 7. Black River Harbor, Ohio.-Nothing has been done here during the past year; but the work of repairing the west pier is now in progress. The channel in July of 1869 was twelve feet deep, or about ten and a half feet deep at low water-an increase of two feet over the depth reported in November last. Available June 30, 1868... Expended during the fiscal year. On hand July 1, 1869... No further appropriation is required. (See Appendix D 7.) $10,000 00 24 58 9,975 42 8. Cleveland Harbor, Ohio.-The west pier has been completed, and the east pier extended so far that its completion may be expected in September. All of which will be expended this year in completing the pier extension. Required, as by previous reports, to give fourteen feet draught, $39,000, which can be profitably expended during the fiscal year. (See Appendix D 8.) 9. Grand River Harbor, Ohio.-The east pier extension has been completed and the effect has been to give an average increase of depth of two feet in the cbannel. Further improvement is deferred until it can be decided whether an extension of the west pier will best accomplish the end desired. Balance available July 1, 1868.. Expended during the fiscal year. $45, 582 40 10, 777 37 Balance on hand July 1, 1869.. No further appropriation is required. (See Appendix D 9.) 34,805 03 10. Ashtabula Harbor, Ohio.-The extension of both the east and west piers has been completed, both running out now to the twelve-foot curve, and they are of equal length and parallel. The contract for dredging the harbor out to twelve-feet depth is let at a reasonable rate, and will probably be completed this year. No further appropriation is needed. Amount on hand June 30, 1868.. Balance on hand July 1, 1869... $48,310 16 28, 412 94 19,897 22 Which is sufficient to complete the dredging, and which will probably be expended by December. (See Appendix D 10.) 11. Conneaut Harbor, Ohio.-The breach made by Conneaut Creek into the lake and behind the east pier has been repaired, and the place secured against a similar accident. The cribs of the west pier extension were sunk in place in June, since which time the entire extension has been completed. Received and expended during the year. Which has been expended in completing the pier work. $14,213 74 9, 000 00 Still to be appropriated, in order to complete the harbor, $6,000. (See Appendix D 11.) 12. Erie Harbor, Pennsylvania.-The work at this harbor during the past year has consisted of the repair of three-quarters of the damaged north pier, and the dredging of the channels over the inner and the outer bars. The former work has stood the storms of fall and winter without any perceptible settlement, proving the propriety of the system of repair adopted. The channel over the inner bar has been deepened to thirteen feet below low water for a width of one hundred feet, and a lump has been removed from the outer bar. There have been expended $21,173 76 in these operations. $15, 150 00 Leaving, of the amount called for in the last annual report. Still to be supplied by appropriation, to which must be added the cost of widening the channel.. Total required... (See Appendix D 12.) 30, 750 00 45,900 00 |
