Climate resilience in the Mitchell water plan area
There have been changes in rainfall and climate since the current Mitchell water plan was established in 2007.
We will review the hydrology within the water plan area (the scientific study of how water moves, is distributed, and is managed) to determine if and how water availability has changed.
We will undertake technical assessment to evaluate possible future impacts of climate variability to water availability in the region.
Learn how we manage climate variability risks.
Queensland's water plans in a variable and changing climate report (PDF, 19MB) identifies climate impacts across each of the water plan areas.
For example, pages 60 and 61 show the below snapshot of observed and projected climate trends for the Mitchell water plan area.
This snapshot includes 2 scenarios represented by a Representative Concentration Pathway (RCP) of 8.5 (high greenhouse gas emissions) and 4.5 (lower greenhouse gas emissions) for the years 2030 and 2050. They indicate:
- average daily temperatures are projected to increase between 1 and 2 degrees centigrade
- average annual rainfall is projected to decrease up to 2% for the high emissions scenario
- average annual rainfall is projected to decrease in 2030 by 2% and in 2030 by 4% for the lower emissions scenario
- average annual potential evapotranspiration (PET) is projected to increase between 6 and 12%.
What do you think?
What rainfall and climate-related impacts have you been experiencing?
For example, you may have come across some of these issues:
- increased water use
- increased evaporation losses from water storages and water courses
- waterholes drying up or holding water for less time.
Tell us how you're managing climate variability impacts (including examples of how you've mitigated impacts).
