Water Storage Levels

Level 1 water restrictions now apply. Learn more

Water supply in the lower Hunter is vulnerable to drought - our dams fill quickly but they empty quickly as well.

Our water levels drop faster than most other major Australian urban centres during hot, dry periods because we have shallow water storages and high evaporation rates. Below is a snapshot of our current storage levels against their longer term averages and also a forecast of where storage levels might get to under dry, wet or average forecast, and when water restrictions may need to be applied.

What can I do?

Water demand from customers also has a major influence on our dam levels. Did you know that households in our region still use an average of about 10% more water than the best performing communities in Australia? There's a lot all of us can do to save our precious resource and be more water efficient, either by following the Water Wise behaviours and choosing water efficient appliances when upgrading household items. Fixing leaks around the house is another way to save water and on your bills. Together we can make a big difference in conserving our most precious resource.
