Scope and Content Note

This series consists of two volumes containing water supply computations for a 1911 survey of the Black River. The first volume contains computations that show the capacity of bodies of water along the black river, measuring the volume of water in millions of cubic feet, the contour under consideration, the average area, and the total flooded area. This volume also contains the water supply volume for canals; calculations of waste weir discharge; computations of storage; the cost of locks and dams; and a summary of the costs of water supply feeders, reservoirs, and dams.

The second volume contains the approximate determination of the capacity of the valley of the North Branch; rainfall and run-of totals; the capacity of reservoirs; and an index to the lines of a proposed Black River Canal.
