This could a be done simultaneously with the construction of the dam, or, if Craigie's bridge is to be reconstructed before long, the relocation of the draw might be deferred for a time. It will be feasible to provide a more convenient passage for small boats than is afforded by the lock already described, either by providing runways (See Plate VII.) or by other suitable means which have not yet been worked out in detail. The plans of the dam have been made in sufficient detail to show that it is entirely feasible to construct a dam and lock at this place, and are also sufficient for making an approximate estimate of the cost of the work, which amounts to $660,000. This estimate includes the cost of the dam and all of its appurtenances from the Charlesbank to the harbor line on the Cambridge side. Beyond the harbor line are flats which would have to be filled in order to wholly complete the dam, but as these flats have already been taken by the city of Cambridge as a part of the park system and are to be filled for this purpose the cost of extending the dam beyond the harbor line has not been included in the estimate. Sanitary Condition Of The Water In The Proposed Basin. I have already indicated that while the tidal portion of the river is at present in an unsanitary condition, it is, nevertheless, in a very much better condition than it would be if it were not for the vast amount of sea water which enters the river at every tide to dilute the sewage. It is obvious, therefore, that if a dam were to be constructed which would prevent the entrance of sea water before the sewage is diverted...
