The &quot;Major Catchment&quot; layer divides each Primary catchment into the tributaries of a primary river. The delineation of a Major Catchment is by the watershed (natural or constructed) of a major drain or watercourse. Examples of major catchments are: Tributary of Yarra River, Darebin Creek, Tarago River and Corhanwarrbul Creek. This dataset provides a consolidated and consistent set of drainage catchments covering the entire Port Phillip and Westernport catchment area (Melbourne Water’s area of responsibility for waterways and drainage). The primary purpose of this layer is for the hydraulic modelling of catchments and waterways, and/or calculations.
