...Charles River Basin Commission last autumn submitted to the War Department its general construction plans for the Charles river dam. The contract has been awarded and work was begun last week. The dam will be erected a short distance below the Craigie or East Cambridge bridge, and the latter will be torn down and a temporary bridge constructed to take its traffic. The cost of the dam, which will not be completed for three years, will be about $2,500,000, or rather less than the original estimate. Unlimited appropriations have been voted by the state legislature and the work...
...Charles River Basin Commission has advertised for bids on its contract for the dam which is to turn the Charles river into a freshwater basin unaffected by the tides. The dam will be built on the present site of Craigie bridge, and its total length will be 1300 feet, the width varying from 140 to 490 feet. It will consist of two masonry retaining walls on pole foundations, the space between them being filled with earth to a depth of from 15 to 50 feet. At the ends the height of the dam will be 21 feet above mean...
...have made the following calculations: earth excavation, 340,000 cubic yards; filling, 400,000 cubic yards; concrete masonry, 41,000 cubic yards; piling, 490,000 linear feet; pine lumber, 1,100,000 feet; spruce lumber, 550,000 feet; riprap, 10,000 tons. There will be two locks in the dam, the larger being 350 feet in length and 45 feet wide, and of sufficient depth to allow a vessel drawing 16 feet of water to pass through at low tide. The smaller lock will be suitable for launches and row boats. Eight sluices will be provided, and in emergencies...
...dam will maintain a basin 8 miles long and will affect the level of the water as far as the dam at Watertown. There will be 17 1-2 miles of shore-line, nearly all of which will be devoted to park purposes, the land having been purchased by the Metropolitan Park Commission and the City of Cambridge. The level of the basin will be about 2 feet below the present mean high tide level...
...benefits of the basin will be realized much sooner than was anticipated by the petitioners who secured the legislative act authorizing the work. Part of the engineering scheme for the construction of the dam provides for a temporary shut-off which will establish the level of the basin at about the same level as the permanent structure. The terms of the contract call for the completion of this shut-off dam by August 1, 1907. Rowing men of the present Freshman class, therefore, will be able to enjoy, for a year at least, the advantages of the greater depth...
