GW System Inflow: Natural Recharge; Incidental AG Recharge; Treated Effluent Recharge GW System Outflow: Groundwater discharge (baseflow); EVT and Underflow

Outflow: Well Pumpage

GW System Inflows: Natural Recharge; Incidental AG Recharge; Treated Effluent Recharge GW System Outflows: Groundwater discharge (baseflow, ≈); EVT and Underflow

Outflow: Well Pumpage
