Water Modelling-Modelled Data-No Plan Environmental Water (No PEW) - Gwydir

To construct a high-level evaluation scenario for the Water Sharing Plan (the Plan) for the Gwydir Regulated River Water Source all account-based Plan Environmental Water (PEW) rules have been removed from the Current Conditions model. Specifically, it included the following PEW rules:

  • Environmental Water Allowance (EWA) stipulated in Cause 64 of the Plan
  • Protection of the minimum (3T) inflow rule stipulated in Clause 61 of the Plan
  • 50:50 sharing of Supplementary water events stipulated in Clause 48 of the Plan

The flow at the following key sites within the river system has been considered in the evaluation analysis:
