  • Scenarios developed for numbers of Bass in impoundment based on future stocking proposed by stocking group or stocking numbers to maintain current fish numbers
  • Dam not expected to overtop in 2016/17 but depends on long range rainfall forecasts

The lake is under the control of SEQWater and the Pine Rivers Fish Management Association carries out fish stocking. Fishing in the lake is subject to a range of restrictions including the areas that can be fished. Fish stocking is carried out under the Stocked Impoundment Permit (SIP) scheme and a permit is required to fish in the lake.
