– = no data available

Recharged volumes are from the Angas and Bremer rivers (1,327 ML) and from River Murray 3,710 ML (Angas–Bremer Prescribed Wells Area in the Murray – SA region).

Recharge was initially carried out to improve the quality of the groundwater and to store surface water that flowed during the non-irrigation season. Currently, the River Murray pipeline capacity is not capable of delivering all water demands during the peak of irrigation season, meaning licensees will need to take water off-peak and store it in the aquifer for later use.
