Notes:
- Calculated from Glenbawn and Glennies Creek Dams evaporation and releases, less storage drawdown and Barnard Reserve inflows.
- Downstream tributaries - assessed by mass balance at Greta. Recorded trib flows were Gauged=127095ML and Ungauged=66,179ML
- Basic rights are not metered. Values presented are those in the Water Sharing Plan.
- Barnard Reserve accumulates from an inter valley physical transfer.
- "Total Barnard Reserve at end of month 0"
- Gauged at Greta (not the end) - flows greater than environmental target are provided
- All unaccounted source flows included in tributary inflows and includes spill from Dams.
- Planned environmental water delivery requirements were met 100% in 2013-14.
