What is Karst? A land area that includes sinkholes, springs, sinking streams, and caves. In karst areas, the fractured limestone rock formations have been dissolved by flowing groundwater to form cavities, pipes, and conduits. Sinkholes, caves, sinking streams, and springs signal the presence of underground drainage systems in karstlands. Unless watersheds are protected, these direct connections between the surface and the subsurface can threaten the quality of our drinking water. The safest watersheds are those in which all residents understand the karst landscape and work together to reduce soil erosion, high-density development, agricultural and urban storm water runoff, overgrazing, improper waste disposal, and pollution.
