The UMDR aims to improve fish habitat and river health for native fish in the upper Murrumbidgee. Native fish populations in the Murray Darling Basin are currently at or below 10% of pre-European settlement levels. The Native Fish Strategy is an initiative of the [link: Murray–Darling Basin Authority] that aims to rehabilitate native fish populations across the basin to 60% by 2054 and to ensure sustainable fish populations and communities throughout the basin.
