NRS-9898 | Report on the Capacity and Requirements of the Board's Stormwater Channels

This Report comprising 7 volumes was prepared for the Board by J.F. McIllwraith in 1970. The Report was compiled as an analysis of the capacity and requirements of the Board's stormwater channel system in the Sydney metropolitan region. Each volume contains plans of the area under analysis, a flow schedule for channels serving the respective areas, and an outline of deficiencies where they occur. The Report is divided into three groupings: Channels very deficient in capacity and subject to severe and frequent flooding (Group A, 3 volumes); Channels deficient in capacity and with some history of flooding (Group B, 3 volumes); and Channels deficient in capacity with no history of flooding (Group C, 1 volume). (6/12587-93). 7 vols.Note: This description is extracted from Concise Guide to the State Archives of New South Wales, 3rd Edition 2000.
