ABSTRACT The dynamic storage of aquifers is the portion groundwater that can potentially drain to any given point along a stream create baseflow. Baseflow typically occurs year‐round in perennial streams, though characteristics and stability are often most important instream processes during extended dry periods (without precipitation snowmelt) when runoff quickflows minimised. term ‘baseflow resilience’ defined for this review as tendency baseflow streams maintain consistent volume water quality year while under stress from climate variability extremes, with anthropogenic stressors such withdrawals, land use change, degradation. ‘Baseflow has, part, user‐defined meaning spanning supply variables primary interest. Watershed directly impact resilience produce non‐intuitive feedbacks enhance some attributes simultaneously impairing others. For example, permeable corridor geology creates strong stream‐groundwater hydrologic connectivity, yet fast drainage via preferential high‐permeability flowpaths lead streamflow not being sustained periods. Also, shallow sources generally more immediately vulnerable extreme events, warming, salinization, transpiration, drought, compared deeper groundwater. Yet drought influenced by lag years, contaminant legacies may propagate through deep receiving waters decades centuries. Finally, irrigation withdrawals intercept would have drained application leach contaminants soil zone unnaturally raising tables, return flows sustain groundwater‐dependent habitats semiarid areas. This covers concept context summarises common hydrogeological controls on, multiscale of, storage. Further, we present several quantitative metrics assess range using both broadly available boutique data types, subset which demonstrated Delaware River Basin, USA.
