Tilting Dams in Water Works Practice
The interesting description, appearing on the first page of this issue, of the dam of the Lock Raven Lake Reservoir, which is part of the water supply of Baltimore, Md., and for which FIRE AND WATER ENGINEERING is indebted to the courtesy of the Scientific American, illustrates one of the important problems that the water works engineer must deal with and is a most practical solution of the difficulty. The accomplishment sought in this case was that of maintaining a level of 192 elevation and yet not interfering with a private reservoir situated just above Lock Raven, only four feet higher. The accomplishment of this by means of the tilting dam superimposed on the main structure and which by a series of opening units automatically allowed enough water to escape, actuated by the pressure behind the dam so as to properly regulate the elevation and avoid the danger of its rising, is the work of V. Bernard Siems, pitometer engineer of the Baltimore city water department. Mr. Siems designed this dam, and its work has proved the wisdom of this wide-awake engineer’s idea. The description as illustrating how an unusual engineering difficulty was met and overcome forms interest reading.
