To manage the complexity of the Namoi Water Resource Plan Area (WRPA), the Namoi Long Term Water Plan (LTWP) has been divided into 36 planning units (PU). For each PU the following local-scale information is provided:
- the location of some key environmental assets identified as part of plan’s development.
- the ecological values, including native fish, waterbird species, native vegetation communities and cultural water-dependent assets that occur within the PUs priority environmental assets
- for regulated PUs, and a few unregulated PUs, the environmental water requirements (EWRs) to support ecological values and objectives at representative gauges in the PU
- for unregulated PUs - 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.
