Groundwater that drains to surface water through seeps and springs is generally referred to as “discharge.” Groundwater discharge is a primary component of stream base flow, or streamflow that occurs between storms, periods of snowmelt runoff, and periods of quick soil drainage.

Dr. Fair is an ecohydrologist with the Eastern Ecological Science Center at the S.O. Conte Research Laboratory in Turners Falls, MA.
Fair leads an interdisciplinary team of fish ecologists, biologists, and hydrologists working to better understand the ecological impacts of streamflow extremes. Our team builds data systems that allow cooperators to share data, explore data, and visualize model predictions.

Flow is a critical variable in streams since it affects aquatic and riparian biological communities and human uses of water (i.e., recreation, public water supply, etc.). Flow regimes are changing due to anthropogenic (e.g., water withdrawals) and natural impacts (e.g., extreme weather events).
