JOSEPH RIPLEY, ASSISTANT ENGINEER. UNITED STATES ENGINEER Office, Sault Ste. Marie, Mich., July 1, 1905. COLONEL: I have the honor to submit the following report of operations for improving Hay Lake and Neebish channels during the fiscal year ending June 30, 1905: REMOVAL OF BOWLDERS FROM ISOLATED SHOALS, CANAL TO LITTLE RAPIDS. Emergency contract dated April 26, 1904, with H. W. Hubbell & Co., of Saginaw, Mich., for hire of steam derrick boat; contract rates, $6.15 per working hour, and 18 cents per pound for dynamite. The derrick boat worked 208.8 hours and was delayed 5.9 hours, and picked up 500 cubic yards of bowlders, besides washing away numerous spots with water jet. Thirty-five pounds of dynamite were used. The total cost amounted to $1,290.32. WIDENING AT LITTLE RAPIDS. Section 1, Item B.-Improving upper entrance channel to Hay Lake from above islands to Frechette Point, a distance of 14,000 feet, for a width of 300 to 450 feet, by deepening to 21 feet at low stage of water of 579.9. The original improvement of 1892 was for 20-foot depth at mean stage of water of 583.3. Contract dated April 11, 1904; Charles Simono, Two Rivers, Wis., contractor; rates, 17 cents per cubic yard, bank measurement, to 21-foot grade, and 8 cents per cubic yard between 21 and 22 foot grades. Material: Clay and sand. Dredging commenced May 7, 1904, and was completed November 15, 1904. Two dredges worked 1,731.6 hours and were delayed 516.1 hours, and excavated 282,217 cubic yards, bank measurement, from an area of 604,000 square yards. The excavated material was dumped in Bay de Wasig. A survey was made through the ice during February, 1905, for final estimate, and check computations of quantities were made from the soundings. Total amount paid the contractor on this section was $56,349.68 for dredging 239,628 cubic yards full rate and 155,670 cubic yards half rate material. Section 2, Item B.-Improving channel between Frechette and Six-Mile Points, a distance of 12,000 feet for varying widths of 600 to 1,700 feet, by deepening to 21 feet at low stage of water of 579.4 from former improvement of 20 feet depth at mean stage of 583.0. Contract dated April 14, 1904; The Lake Erie Dredging Company, Buffalo, N. Y., contractors; rates, 133 cents per cubic yard, bank measurement, to 21-foot grade, and 6 cents per cubic yard between 21 and 22 foot grades. Material: Clay and sand, Dredging commenced May 7, 1904. Three dredges worked 3,332.5 hours, and were delayed 727.1 hours, and from an area of 389,000 square yards excavated 635,262 cubic yards, scow measurement, which was deposited in Bay de Wasig. The estimated bank measurement is 484.414 cubic yards; this is divided into 442,421 cubic yards full rate and 41,993 cubic yards half rate. A survey was made during February, 1905, for a season's estimate, and computations made for check on estimated bank measurement. About 45 per cent of the dredging has been done in 56 per cent of the contract time of 350 good working days. DEEPENING NINE-MILE POINT SHOAL. Section 3, Item A.-Removal of shoals in Mid Hay Lake, covering an area of 1,400 feet long by 500 to 950 feet wide, to a depth of 22 feet at low-water stage of 579.3, from previous improved depth of 21 feet at mean stage of 583.0. Contract dated April 11, 1904; H. W. Hubbell & Co., Saginaw, Mich., contractors; rates, 98.4 cents per cubic yard, bank measurement, to 22-foot grade, and 49.2 cents per cubic yard between 22 and 23 foot grades. Material: Bowlders, stones, sand, and hard pan. Dredging commenced May 11, 1904, and was completed on June 7, 1905. Three dredges and one derrick boat worked at varying times 2,434.4 hours and were delayed 845.6 hours, and excavated 76,928 cubic yards, scow measurement, estimated at 70,608 cubic yards, bank measurement. The total excavation made under the contract has been divided into 56,188 cubic yards full-rate and 23,737 cubic yards half-rate material, but the final estimate computations may add about 1,000 cubic yards to the half-rate material. The shoal was swept over with the sounding raft with bars suspended at established grade and the work accepted on June 24, 1905. One hundred per cent of the work has been done with an expenditure of 100 per cent of the time. ENG 1905 M-143 |
