Book excerpt: Excerpt from Description of the Boston Water Works: Illustrated With Five Lithographic Plates Lake Cochituate, formerly known as Long Pond, the main source from which the supply of water for the city of Boston is taken may be considered a chain of natural, subsiding Reservoirs of water, three in number, having a general direction nearly north and south; its extreme length in a direct line being about three and one-half miles, and its greatest breadth about eighteen hundred feet. Two county roads crossing it, divide it into three nearly equal parts, which for convenient reference, are designated as the Northern, Central and Southern Divisions. The water gradually increases in depth from the shore, in each division; at high water, or when raised ten feet above the flume, or thirteen feet and thirty-six one-hundredths above the bottom of the Conduit; its greatest death is about seventy-two feet in the Southern, fifty in the Centre, and sixty-four feet in the Northern Division. When the water is at this elevation, the superficial area of the Lake is estimated to be eight hundred acres. At 3 ft. 5 in. above the bottom of the Conduit, the area of the Lake is 490 acres, and its capacity is 13,313,000 wine gallons; for every inch added to the above height up to 5 ft. there is an increase of one acre in area, and the total capacity is increased to 270,834,000 wine gallons; for every succeeding inch up to 7 ft. there is an increase of area of 3 acres, and the capacity is then 636, 420,000 gallons; from 7 ft. to 10 ft. there is an average gain in area per inch of rise, of 2 acres, and the capacity is increased to 1,234,028,000 gallons; in the next 16 inches of rise there is a gain of 23 acres and a capacity increased to 1,527,132,000 gallons; for the following 24 inches there is an increase of area of 5 acres per inch of height and at 13 ft. 4 in., or high water mark, the total capacity of the Lake is 2,011, 165,000 wine gallons and the area 801 acres.
