AquiferWatch is a tool that water users can use to predict aquifer levels a month in advance for managing abstraction relative to cutoff levels. Scenario simulations for dry-weather conditions are computed with the aim to estimate lead-times to critically low levels. See methods for further information on the modelling approach.

Aquifer Storage

Depicted below is the percentage of sustainable storage which is only about 10% of the total storage of the unconfined Wairau Aquifer. See methods for further information.
