The planned joint use of surface and groundwater to improve overall water supply reliability.
The operation of a groundwater basin in combination with a surface water storage and conveyance system. Water is stored in the ground water basin for later use in place of or to supplement surface supplies. Water is stored by intentionally recharging the basin during years of above-average water supply.
A program that coordinates the storage of imported surface water supplies in local ground-water basins for future withdrawal and use.
