Conclusions
Page 14
- Water levels are generally steady. Limited response to
rainfall in the 2010/11 wet year.
- The drawdowns in monitoring bores are indicative of areas
- f groundwater extractions and drawdown spread is limited to
local areas of groundwater extractions.
- Groundwater extractions have not exceeded the Long Term
Average Annual Extraction Limit (LTAAEL) except for 2018/19.
- Temporary (71T) and permanent trading (71Q) remain
