Karst and the USGS

Welcome to the USGS Karst Website. This website presents information on USGS research on karst aquifers, which are a vital groundwater resource in the United States. Here you can learn about past and current USGS karst research, with information on ongoing studies, publications, and key contacts for major karst areas. Click on an aquifer on the map below, or select one from a list of aquifers.

Turner Falls Turner Falls. The largest waterfall in Oklahoma. Springs discharging from the Arbuckle-Simpson aquifer into Honey Creek are the source of water to Turner Falls. (Photo by Noel Osborn, Ok. Water Resources Board) Read more about the Arbuckle-Simpson aquifer...
Main Barton Spring, with Barton Springs Pool drained Main Barton Spring, with Barton Springs Pool drained. USGS Research Hydrologist Barbara Mahler makes water-quality measurements of Main Barton Spring. The spring normally discharges under the presssure of 12 feet of overlying water, but here that water had been lowered temporarily, to quantify the water-quality changes it causes.

Sinkholes from subsidence event, Florida, February 1998
Sinkholes from subsidence event, Florida, February 1998. Over 700 sinkholes formed over a 20-acre area in response to well drilling. A well had been drilled about 20 feet into a cavity, when air-lift well-development methods began being used. Immediately after, small sinkholes started appearing in the surrounding area. Subsidence continued for several hours, with sinkholes closest to the well expanding to become the largest in the area.

Waterfall in Mammoth Cave Nat. Park Waterfall in Mammoth Cave Nat. Park. Recent rainfall has activated a large waterfall in the so-called Mammoth Dome, cascading water down on the path used by visistors through the cave.

This website allows you to browse for karst reports and articles authored by USGS researchers, and find links for other karst resources. There is also an overview of karst and its properties.

This website is maintained by members of the USGS Karst Interest Group, whose (KIG), who investigate karst across the United States.
