Scope and Content: The Charles River Basin Commission was established in 1903 to make examinations and plans for and to carry out the construction of a dam across the Charles River between Boston and Cambridge.  To carry out this task, engineers hired by the commission conducted surveys, took measurements, and made calculations and estimates that were used to plan and execute construction of the dam.  Engineer calculation and field notebooks contain for the most part calculations and estimates made in the office from data collected in field, although three notebooks contain more preliminary data.
