Sustainable Yield

Comment about sustainable yield figure: 

An assessment of 40000 Ml/yr for sustainable yield was made in 2000 based upon initial water balance methods and is to be revised with the completion of the groundwater model.

Data Availability,Gaps and Recommendations

Data Availablility:

In excess of 1400 observation bores, both private and State owned, are located within the Burdekin River Irrigation Area (left bank) GMU. The availability of water level data is high, with water level monitoring conducted in 394 observation bores, some from 1964 to the present, on an approximately bi-monthly basis. Comprehensive water quality data exists for 545 observation bores within the GMU, with recent analysis to 1999. A groundwater flow and management model of the GMU is presently being developed to investigate the impact of different combinations of water supplies on groundwater levels.
