Water Storage Levels

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 drought because we have shallow water storages and high evaporation rates.

The graph below shows the total volume of water stored in the dams supplying water to the Lower Hunter region. This supply is drawn from a combination of surface storages and groundwater resources.
