Includes description, asset section (for As Constructed drawings) and key attributes. This layer is intended to help identify the location of Melbourne Water's drainage assets for asset management and maintenance purposes. Waterway (Reach) layer created from original FIS 1:50K (Vicmap Hydro) streams data set which included only those waterways within catchments of greater than 60ha. Waterways (Reach) Rectification project undertaken 2001 to 2003 to review and correct the extent of the waterways reach network to ensure a complete data set exists (using the Drainage Metropolis Boundary, 50K data, 1:2500 Drainage Record Plans, Drainage Limits data, orthophotos, as constructed and/or design drawings, contour data and Melway Street Directory). Waterway (Reach) extents defined and attributes populated in GIS and Hansen (AMIS) for all records including assigning nodes and node numbers (for start / end points) and removing any reaches less than 100 metres in length that are predominantly channel assets. Waterways in extended area incorporated in 2005 using Vicmap Hydro data and aerial imagery, then updated in 2009/10 using Lidar survey data (contours). Data is maintained using Lidar survey data (contours) and 60 ha limits. Please refer to metadata for each record in dataset for specific source / accuracy information.
