Spatial data set of valley boundaries in the Murray-Darling Basin used to support the Commonwealth Environmental Water Holder’s (CEWH) monitoring, evaluation and research activities. Modified from the Sustainable Rivers Audit (SRA) valleys to partition the Selected Areas used in the Long Term Intervention Monitoring (LTIM) project and Flow-MER program and to align with water accounting in the Basin.

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 CEWO to demonstrate environmental outcomes and adaptively manage the water holdings. For more information and reporting using these data see https://data.gov.au/data/dataset/cewo-mer-program.
