Areas that are added are mapped by polygons from the ANAE classification of the Murray-Darling Basin data set that were identified as receiving inundation by Commonwealth environmental water by the Commonwealth Environmental Water Holder’s (CEWH) Long Term Intervention Monitoring (LTIM) project (2014-2019) and the first two years of the Monitoring, Evaluation and Research (Flow-MER) program. The MDBA published Murray-Darling Basin managed floodplain (https://data.gov.au/data/dataset/murray-darling-basin-managed-floodplain) is a spatial data set that estimates the extent of the Murray-Darling Basin that can be influenced by environmental water under the Basin Plan. It includes: • actively managed areas that can receive environmental water via large headwater storages or via The Living Murray ‘environmental works’ sites on the River Murray floodplain • passively managed areas that receive environmental water via flow rules in water resource plans or via natural events • areas that may be inundated with high flows if key constraints are overcome The CEWH’s Flow-MER program examines the contribution of Commonwealth environmental water to the environmental objectives of the Basin Plan 2012 (Basin Plan) and is assisting the CEWH to demonstrate environmental outcomes and adaptively manage the water holdings.

Ecosystem Diversity leader MDBA Flow-MER acknowledges the First Nations peoples as the Traditional Owners and Custodians of the lands, waterways and skies of the Murray-Darling Basin. We respect their continuing connection to culture and Country, and we thank them for their knowledge and science and the values reflected in these data.

The MDBA managed floodplain was used as the master template to erase the ANAE polygons in overlapping areas. Valley names assigned by GIS “nearest” analysis. The logic supporting the original estimation of the managed floodplain by MDBA is unknown to this data set author.
