The effects of groundwater pumping on streams, springs, wetlands, and riparian vegetation are of concern in many parts of the United States. These concerns commonly stem from the need to protect existing surface water rights and to preserve groundwater dependent terrestrial and aquatic ecosystems. This session explores pumping-induced effects on surface water and evapotranspiration, including depletion of surface water and changes in surface water temperature and chemistry. Managed recharge to enhance surface flows also will be considered. Topics discussed include: • Methods for understanding and managing the magnitude, timing, and locations of streamflow depletion • Case studies of streamflow depletion and managed recharge to enhance streamflow • Monitoring to better understand streamflow depletion • Regulatory aspects of groundwater pumping that may deplete surface water.
