...Dana '74, Mr. H. S. Pritchett, president of the Massachusetts Institute of Technology, and Col. S. M. Mansfield, of the United States Engineering Corps. The committee recommends that a dam be built near the present site of the Craigie bridge and that a fresh-water basin be maintained at a permanent level. The report is most thorough and exhaustive, and its preparation required an immense amount of work covering a period of about two years. The engineering problems connected with the project, while complicated, are entirely capable of solution. The chief reasons for the construction...
...contended by those opposed to the plan that the water in the proposed basin could not be kept clean, that the basin would therefore be dangerous to the residents living on the banks, and that it would be prejudicial to the interests of Boston harbor...
...large force of engineers, chemists and bacteriologists, under the charge of Mr. Freeman, chief consulting engineer, has been at work during the summer. As no satisfactory chart existed, a thorough survey and sounding was made of the basin and its tributary canals, and a chart was constructed similar to those of the Coast Survey. The currents in the harbor have also been carefully studied and charted...
...chief objections to the building of the dam has been the fear that sewage would accumulate in the basin. With a view to ascertaining the truth of this statement, chemical and bacteriological analyses of the water were made under various tidal conditions, especially in regard to the dissolution of sewage in still fresh water; and all the sewers opening into the basin and its tributaries were examined both in dry weather and in storm overflows. The temperature of the water has been systematically watched all summer...
