Data and information required for water accounts for the Gwydir subregion are primarily held in the Australian Water Resources Information System (AWRIS) (Bureau of Meteorology, 2014). The information that would be required for a water account includes:
- water volumes held in surface water storages and surface water systems
- surface water diversions
- surface water trading volumes
- surface water entitlement, allocation and use, including surface water for industrial use and town water supply
- location information for all water account data.
Data and information can also be sourced from the continuous monitoring database held by the NSW Office of Water (NSW Office of Water, 2014a) and documented in water sharing plans (NSW Office of Water, 2014b).
