Ensure there is enough water (quantity)
While current predictions for rainfall do not suggest dramatic future changes to the total annual rainfall and groundwater recharge, climate change is affecting the frequency and severity of storm events. Climate change predictions point to changes in seasonal water availability that could result in uneven summer rainfall. The criteria used to protect streams, rivers (environmental flows) and aquatic ecosystems will be set out in regulations and/or statutory water allocation plans. These will relate directly to water availability under prevailing and future climatic conditions.
