When the extension contemplated under the appropriation of July 5, 1884, is built, it is thought that the pier will be completed to a sufficient extent to warrant the establishment of a permanent light by the LightHouse Board. It is contemplated to expend the appropriation of $15,000 made July 5, 1884, in extending the north pier 200 linear feet, in beginning the construction of a south pile-pier, and in dredging. The work contemplated during the fiscal year ending June 30, 1886, is the further extension of the pile-pier already begun, and dredging. Money statement. July 1, 1884, amount available.............

COMMERCIAL STATISTICS FOR THE YEAR ENDING DECEMBER 31, 1883. [Obtained from Mr. Jesse Spalding, Chicago, Ill.] $21.96 Original estimate (see Report of Chief of Engineers 1874, I, page 139). -$212,000 88,000 300,000 200,000 Appropriated .... The project for the improvement of this harbor consists in the construction of two parallel piers, about 400 feet apart, extending from the mouth of the Menomonee River to the 16-foot curve in Green Bay, with dredging between the piers so as to afford a channel of entrance not less than 14 feet deep at low water connecting the deep water in Green Bay with the deep water in the river. This work was begun in 1871. During the year ending June 30, 1884, under a contract dated September 16, 1882, with Messrs. Truman & Cooper, the south pier was extended 200 linear feet, by the construction of 4 cribs, each 50 feet long, 20 feet wide, and 123 feet high; partial superstructure (4 courses) was built over 300 linear feet of the same pier. The water being shoal, a trench was dredged to a depth of 14 feet below datum, and a foundation of stone prepared therein of about 4 feet in thickness to receive the cribs. The north pier was extended 50 linear feet by sinking one crib 50 feet long, 24 feet wide, and 163 feet high, which finished the contract. Before this could be done, the outer crib, No. 12, of the north pier, which had been moved about 13 feet toward the channel by ice, had to be replaced. The contractors agreed to do this work for $800, as stated in the Annual Report for 1883, on the improvement of the harbor. their request they were relieved from this agreement, and the crib was realigned by hired labor at a cost of $623.99. An interval of 4 feet remaining between the crib and the completed part of the pier was closed with pine shutters and horizontal timbers, bolted to two vertical timbers, abutting against the horns of the adjacent cribs and filled in with stone. (Report of Mr. Charles Crosman, assistant engineer, appended hereto.) The present condition of the harbor is as follows: The north pier is 1,854 feet long and the south pier is 2,710 feet long. The outer 650 feet of the north pier and outer 800 feet of the south pier are composed of crib-work, the rest being slab and pile pier. Since the improvement was begun, 205,828 cubic yards of material have been dredged, resulting in a channel 200 feet wide, 100 feet of which width has a depth of 14 feet of water and the other part a depth 12 feet. The project upon which the original estimate was based contemplated the extension of the piers to the 16-foot curve, with dredging to secure a channel 14 feet deep between the piers up to the shore-line. The present pier extension has already reached a point 500 feet in advance of the position of the 16-foot curve at the time of the aforesaid estimate, the present end of the north pier standing in over 17 feet of water, while the south pier, which projects 100 feet further in the lake than the north pier, stands in about 10 feet of water. This difference in the depth of water at the ends of the north and south piers is caused by the rapid shoaling of the bay just south of the north pier. As stated in the Annual Report of 1882, the surveys of 1867 and 1881 showed that between those dates the 12- and 18-foot curves over this shoal had advanced from 800 to 1,000 feet into the bay, and that this shoaling, while largely due to the combined action of shore drift and the discharge of the Menomonee River, has been unduly augmented by the improper dumping of materials dredged from the river by the mill owners. . The extension of the piers since then would naturally tend to prevent this shoaling, and it is thought that by extending them to the 18-foot curve in the bay all danger of obstruction from this source will be obviated. The estimate for this extension, as given below, is $100,000, or $88,000 more than the estimate under the original project. ESTIMATE FOR EXTENDING THE PIERS TO THE 18-FOOT CURVE. For reasons stated in the annual report on this harbor in 1882 and 1883 (see Report of Chief of Engineers, 1882, page 2126, and for 1883, page 1641), an additional estimate is required. To extend the piers to the 18-foot curve, with necessary dredging and repairs (including new superstructure) to the pile piers that were built in 1871-74, the following revised estimate is submitted: North pier (terminating in 22 feet of water): 500 linear feet of crib-pier, 24 feet wide, at $70.. South pier (terminating in 184 feet of water): 300 linear feet of crib-pier, 20 feet wide, at $60 50 linear feet of crib-pier, 24 feet wide, at $70 Dredging 85,000 cubic yards, at 25 cents Rebuilding superstructure for 1,200 linear feet of pile-pier. Superintendence and contingencies... $35,000 21,000 3,500 21,250 9,250 10,000 100,000 Amount required in addition to the former estimate to complete the 12,000 28,000 The south pier of this harbor is extensively used by the Menomonee River Lumber Company for the storage of lumber; about 1,400 linear feet of the pier being now devoted to that purpose. |
