This data contains points representing drain and waterway outlet locations, associated with a natural waterway or channel centreline, within the Greater Melbourne region. This region includes the Port Phillip Bay and Western Port coastlines. Points are captured to show the indicative location of the endpoint for a waterway or channel as geographic coordinates.

The data table includes minimal attributes to assist in identifying the feature.

Data was created using the waterway (Reach) layer 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 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 dataset row record for specific source / accuracy information.
