Climate & the Mid West
Renowned for its unique natural environment, the Mid West offers long stretches of coastline with limestone cliffs, scenic sand plains, and beautiful seasonal wildflowers. The region is one of only 5 areas in the world recognised for its biodiversity.
Average temperatures in the Mid West are expected to increase across all seasons. Changes to summer rainfall are a little uncertain but decreases in winter rainfall are likely. This could threaten the sustainability of our groundwater sources.
Increased extreme rainfall events are expected. We may also see extreme sea-level events such as erosion of the coastline.
The Mid West is entirely dependent on groundwater resources. Access to reliable water resources plays a key role in sustaining the vibrant local economy. Groundwater also sustains rivers, wetlands and bushland of social, cultural and ecological significance.
The Carnarvon horticultural industry is a major part of the local economy. It relies on intermittent flows in the Lower Gascoyne River to recharge the aquifers. As the need for water is increasing, demand in the Mid West could double within the next 30 years. Water allocation planning is focused on groundwater and maintaining a reliable water resource.
Did you know?
Approximately 30% of all treated wastewater in the Mid West region is recycled. All of the treated wastewater from the Exmouth, Carnarvon, Kalbarri and Dongara is used to irrigate parks, gardens and ovals.
Further opportunities for increasing re-use of treated wastewater exists in the Narngulu area.
We continue to work closely with communities and stakeholders in the Mid West to achieve sustainable water practices.
Water saving programs
Just like other regions in WA, we work with communities and businesses throughout the Mid West to reduce water use through a range of programs including the Waterwise Business Program, Waterwise Towns Program and Waterwise Councils Program.
We can all help
We can all take action to fight climate change and reduce our water use. Find out what you can do to save water starting today.
Mid West water supply
With average temperatures and rainfall changing, we have plans to tackle the effects of climate change and secure water supplies in the Mid West.
