Scope and Content Note

The series consists of discharge data, tables of water levels, survey reports, and other hydrologic data gathered by the Superintendent (later Department) of Public Works to plan for canal improvements and related flood control. During the 1920s responsibility for flood and water control was vested in that office (later the Department of Environmental Conservation assumed the responsibility). This material may also contain the raw data, and perhaps a draft copy of an annual or special report.
