Ozark Cavefish Refuge Highlights Groundwater Protection Ahead of 35th Anniversary

Protecting a cave fish starts well beyond the cave entrance. A September 28 U.S. Fish and Wildlife Service update on Missouri’s Ozark Cavefish National Wildlife Refuge points to groundwater protection, neighboring landowners and restricted cave access as the work behind its approaching 35th anniversary.

The 40-acre refuge was established on October 22, 1991, and protects Turnback Creek Cave Spring, the outlet of an underground stream. The adjoining Paris Springs Conservation Area shares the job of protecting this habitat. Missouri Department of Conservation staff help manage access to the cave and work with landowners in its recharge zone—the land where water enters the underground system.

Ozark cavefish were federally listed as threatened in 1984. These small, blind fish live in caves, sinkholes and underground springs in Arkansas, Missouri and Oklahoma. Turnback Cave also supports federally endangered gray bats. Water pollution, disturbance and changes in water levels put the cave habitat at risk; declining bat populations can also affect the food available to cavefish.

The practical concern is what reaches the groundwater. Pesticides, chemical spills, runoff, eroded soil and garbage can travel through the system before reaching the fish. The agency recommends maintaining septic systems, controlling animal-waste runoff, keeping vegetation between fields or homes and streams, and retaining woods near cave entrances. Protecting habitat here means paying attention to land use above it.

Turnback Cave remains closed to the public to help prevent the spread of white-nose syndrome in bats. This anniversary update is not an access opening or a new harvest rule. Its useful message is that protecting a small refuge also depends on how surrounding land and water are managed. Visitors should respect the closure rather than treating the story as an invitation to enter the cave.
