An area where there is a concentrated discharge of groundwater that appears as a flow of water at the surface. The distinction between springs and seepages is arbitrary. Vast amounts of groundwater discharges continuously to rivers and lakes, the majority of which occurs unseen in streambeds or as bank seepage. A “spring-fed” river may not have a visible “spring.” There are many different geologic and hydrologic circumstances that can result in springs. Wetlands, springs, and seepages may occur where the water table intersects the land surface.
