Caption

Locations and select hydrological characteristics of 42 headwater catchments sampled for this study. Catchments were distributed across five major drainage basins of the Intermountain West (a). Tritium-derived water ages for winter baseflow (b) and spring snowmelt (c) were older in high-permeability sedimentary catchments than in low-permeability hard rock/ shale catchments. Mean annual runoff efficiency (d) and calculated catchment water storage (e). Red and blue points correspond with high- and low-permeability catchment, respectively.
