Isaac Regional Council wishes to advise the Clermont community that the water restriction trigger levels for Theresa Creek Dam (TCD) have been updated following results of a water supply analysis.

Following community feedback, Council conducted a robust investigation into water restriction trigger levels to ensure the ongoing delivery of a sustainable and reliable water supply to Clermont from TCD.

Preliminary data from the investigation became available in December 2020, which led to the introduction of an interim Level 1 trigger level of 2.1m below spillway. The final investigative report has now been received and the results support updating the water restriction trigger levels for Clermont from TCD.  

The assessment was undertaken with consideration to historic rainfall/evaporation, Australian Water Balance Model parameter sets, township demands, storage, spillway/weir discharges, initial water levels, recent bathymetric survey information, and infrastructure operational criteria and concluded that changes could be implemented to all Levels of Water Restrictions in Clermont.

Based on this information, Council adopted the updated Schedule 3 – Water Restrictions Trigger Levels Guideline for Clermont on Wednesday, 24 March 2021 as follows:
