This document discusses the role of data from Deep Well Logging Recorders (DWLRs) in estimating groundwater resources. DWLRs provide high-frequency water level data that can help understand recharge processes and parameters. Their data allows identifying accurate peaks and troughs in the water table to define optimal periods for water balance studies estimating specific yield and rainfall recharge. DWLR hydrographs also aid in determining rainfall amounts needed to initiate recharge, lag times between rainfall and recharge, effective rainfall events, and periods of evapotranspiration loss - all improving the accuracy of water balance assessments and groundwater resource estimation.
