B 7. GRAND HAVEN HARBOR, MICHIGAN. The pier on south side of channel was extended 100 feet, and the old pile-work built by the Detroit and Milwaukee Railroad Company, forming a part of the same pier interior to portion repaired, for a distance of 465 feet, as shown in blue on accompanying sketch. The work during the present season is being done by Messrs. Squire & White, they being the only bidders, at the following prices: Abstract of contract for improving harbor of Grand Haven, Michigan— Messrs. Squire & White. Tearing away old work pier, per running foot.. $0 16 07 15 2 25 15 00 12 06 10 3.00 07 15 1 75 To complete the improvement of this harbor there is necessary1st. A pier on the north side of the entrance to the river; and, 2d. A further repairing of old pile pier, built by the railroad company on south side of channel, for a distance of 600 feet, from repairs made this season inward. The necessity for a north pier has been fully set forth in previous reports of Brevet Colonel J. B. Wheeler, and the same necessity still exists. This pier will be 1,700 feet long, and will cost $200,000. The repairing of the old south pier will cost $14,000. This harbor is the most important of all those on the east shore of Lake Michigan, and is by far the best; and when once the proposed improvements are completed, it will be a long time before any money need be spent on it. Grand Haven is the port of entry for the district of Michigan, which includes all harbors from Aux Becs Scies south to St. Joseph. It is an important point, being one terminus of the Detroit and Milwaukee railroad, and on an extensive line of communication between the East and West. It is also a lumber market of some importance. It has a lighthouse. Statement of vessels entered and cleared Grand Haven Harbor, in the district of Michigan, during the year 1868, showing the number, tonnage, crews, and cargoes. During the past fiscal year five cribs (32 feet by 20 feet) have been placed on line of south pier, extending it 160 feet, and one crib (32 feet by 20 feet) on north pier, and the superstructure finished. During the winter the south pier settled very irregularly, and the outer crib was moved from its place. By virtue of paragraph 2, Special Orders No. 38, dated Headquarters Corps of Engineers, Washington, D. C., May 7, 1869, a board of engineers assembled May 13, 1869, for consideration of certain structures for harbor improvements on Lake Michigan. In accordance with the opinion of the board, which was approved by the Chief of Engineers United States Army, the following work to improve this harbor will be done the present year: An enrockment will be placed along the side of the south pier to prevent a further scouring out of the sand; the south pier will be repaired; a crib superstructure will be built to prevent a breach between the cribwork and the shore, where the channel on both sides is now protected by a brush pier; And a pile revetment will be built at the head of the cut, to prevent the stream washing out the sand and depositing it on the outer bar. In addition, the point at the head of the cut should be dredged away in order to straighten the channel, which, together with the necessary revetment, will require an additional appropriation of $10,000. Black Lake is in the district of Michigan, twenty-two miles south of Grand Haven, the nearest port of entry. The nearest light-house is at the mouth of the Kalamazoo River, eight miles distant. It is a fixed light of the sixth order. Holland is at the head of the lake, six miles from the mouth, and is the nearest settlement. The contract was accordingly awarded to F. Stewart White, he being the lowest bidder on all the items. 4 41 81 926 12 27 10 12 40 3.75 cub. ft. $11, 506 90 12, 095 00 14, 616 10 11,597 25 13 97 2 65 12345 Statement of vessels entered and cleared Black Lake Harbor, in the district of Michigan, during the year 1868, showing the number, tonnage, crews, and cargoes. MOUTH OF KALAMAZOO RIVER, (SAUGATUCK.) No work was done at this harbor, as it was not until an accurate survey could be made that proper plans and estimates could be made. They were laid before a board of engineers, convened by virtue of paragraph 2, Special Orders No. 70, dated Headquarters Corps of Engineers, Washington, D. C., July 16, 1869. The board of engineers approved the plans and estimates, and, under the further approval of the Chief of Engineers, steps were taken at once to commence the work. The work proposed for the present season's work is to revet the left bank of the river, as shown on the accompanying sketch, from A to B. It is hoped that this will be completed by the 1st of November. The improvements, shown in red, on the north side of the entrance to the river, should be made to complete the improvement of the mouth of the river. The present piers at the mouth of the river were built by the local authorities, and in building them they contracted the stream so much that at high water in the river the piers are much endangered. To obviate the danger it is proposed to build a north pier and interior revetment, as shown on the accompanying sketch, and remove the present slab revetment. These improvements will cost $75,000, which amount can be profitably spent during the fiscal year ending June 30, 1871. Saugatuck is in the collection district of Grand Haven. It is not a port of entry. There is a light-house of the sixth order on the north bank of the river, situated on a rise of 18 feet.

During the fiscal year eight cribs (32 feet by 20 feet) were placed on the prolongation of the north pier, and the superstructure built thereon. During a heavy northwest blow last spring the outer crib of the north pier was carried away, and this was replaced and ballasted with stone.

Amount required for fiscal year ending June 30, 1871, $72,000. To complete the proposed improvement at this harbor the piers should be extended each 400 feet, which would cost $52,000. The old slab pier should be removed, as shown on the accompanying sketch, in order to widen the entrance to the river, and the channel should be dredged to a depth of 12 feet. The latter two items would cost $30,000. The bottom of the channel is of blue clay, and will require but little dredging after a good channel shall have once been made. A railroad is now being constructed between this place and Kalamazoo, Michigan, which will bring considerable shipping to this point. South Haven is situated about sixty miles south of Grand Haven. It is important as a harbor of refuge, and as an outlet to the lumber district of the counties of Allegan and Van Buren. Statement of vessels entered and cleared at South Haven, in the district of Michigan, during the year 1868, showing the number, tonnage, crews, and cargoes. No work has been done during the past fiscal year. The money expended was for work already done. To permanently improve this harbor the south pier should be extended in a direction north 780 west from the present west end for a distance of 928 feet, at a cost of $58,000.
