To help manage the complexity of the Murray–Lower Darling Water Resource Plan Area, the Murray–Lower Darling Long-Term Water Plan (LTWP) has been divided into 37 planning units (PUs). Planning units delineate areas with a unique set of mechanisms for managing water for environmental outcomes. Planning units (PUs) are classified as either: a) regulated (or which can be affected by regulated water), or b) unregulated.
This document forms Part B of the LTWP and provides local-scale information for each planning unit including:
- The location of priority environmental assets as identified through LTWP development.
- The ecological values, including native fish, frogs and waterbird species, and native vegetation communities that occur within the planning unit.
- For planning units that are regulated, or that can be affected by regulated water (PUs 1–19), environmental water requirements, at representative gauges, to support achievement of the LTWP objectives and targets.
- For planning units that are unregulated (PUs 20–37), an evaluation of the impact of water resource development on local hydrology and recommended management strategies for mitigating these changes to meet LTWP objectives and targets.
The planning units are presented in two section:
- Section 2 contains PUs 1–19, which are regulated or can be affected by regulated water.
- Section 3 contains PUs 20–37 that are unregulated and unable to be influenced by regulated water deliveries.
