The source dataset is identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement. This dataset presents the daily stream flow data for gauge 419076, and baseflow estimates. ## **Purpose** This dataset was created during the investigation into surface water - groundwater interactions in the Namoi subregion. ## **Dataset History** Total flow and date of measurement values came from the source file. The River Analysis Package was then used to determine baseflow. The Lyne and Hollick (1979) digital recursive filter, as described in Nathan and McMahon (1990), was used. ## **Dataset Citation** Bioregional Assessment Programme (2017) Surface water gauge 419076 flow analysis.
