Excerpt from Report of the Committee on Charles River Dam: Appointed Under Resolves of 1901, Chapter 105; To Consider the Advisability and Feasibility of Building a Dam Across the Charles River at or Near Craigie Bridge A dam with surface and drawbridge at grade' 22, Boston base, will result in frequent interruption of street traffic over the dam, owing to the necessity of opening the draw for all vessels requiring more than 12 feet head room. On this account, with a view to less frequent obstruction of the highway, the chief engineer of the committee recommends a high dam, with a surface and drawbridge at grade Boston base, which would allow the passage of tugs and mastless vessels without opening the draw. Studies for such a dam, both of solid masonry and with a steel viaduct, have been prepared, though it is probable that the former is pref crable, as the cost of maintenance of a steel structure would offset the decreased expense of construction. These later studies have resulted in some modification of the figures given on pages 12, 31 and 32 of the report of this committee.
