The state of Missouri is a hidden gem for cave & cavern scuba divers. Waynesville, the heart of Missouri cave country, is also home to Roubidoux Spring. Roubidoux Spring is a notable landmark freshwater spring. It is often mentioned as one of the best cave diving springs in the country and is routinely allowed to QUALIFIED and certified cavern or cave divers. ALL DIVERS must register with Waynesville Police Department (573.774.2414) before entering.

“Roubidoux Spring
Summary of Exploration thru Sept. 18, 1977
Prior to September 1977 several people had made relatively short penetrations into the upper level passage of Roubidoux Spring- Carlson, Delaney, Rimbach, and Tatalovich.
During the summer of 1977, Carlson and Delaney made several dives to the limits of the then known passage in an effort to extend penetration. Their maximum penetration was 425 feet and a maximum depth of 120 feet.
On September 3, 1977 Miller and Fogarty made their first dive in Roubidoux Spring. They reached the end of the Carson-Delaney line, found the lower level passage, and added 570 feet of line for a total penetration of 995 feet. The lower level passage runs at an average depth of 140 feet and ranges from 5 feet high and 12 feet wide to 20 feet high and 50 feet wide. On the afternoon of September 3, Miller and Fogarty made a second dive and added another 435 feet. The new penetration was 1430 feet. The passage size, direction, and depth were holding a relatively constant at termination.
September 4, 1977: Miller and Fogarty made a survey trip into the lower level, starting at the end of the Carlson-Delaney line surveying 535 feet. They also removed 35 feet of line to center line in the passage.
A minor decompression accident occurred on this dive causing Miller to be hospitalized for a short period. This delayed further exploration for two weeks.
September 17, 1977: Miller and Fogarty pushed to the end of the line in Whichaway Ave. and started adding line. They immediately entered the “Big Room”, which is 40 feet high and 80 feet wide, depth on the floor was a constant 160 feet. The floor was smooth hard silt with very little breakdown in contrast to the floor in Whichaway Ave. which is all porous breakdown. 225 feet of line was added, making a total penetration of 1620 feet from the entrance and a maximum depth of 160 feet. The Big Room was remaining constant at the termination of the dive.
September 18, 1977: Miller and Fogarty made a survey dive and routinely surveyed the back part of Whichaway Ave.
September 18, 1977: Miller and Fogarty made a survey trip on the Carson-Delaney section of the line, completing the survey of the known passage.
On each dive into the lower level passage blind cave crawfish and blind fish were sighted. No more than three of each were ever sighted on a given dive and their size seemed to be small.”

This survey from 1997 shows two areas, “Room O’ The Endless Line” and “Big Cave Country” that were not known at the time of the 1977 survey. This image has been altered to highlight these additions. For the complete map visit http://cavdvr.tripod.com/images/roubmap.jpg.

Roubidoux Spring Cave will be offered during the National Speleological Society (NSS) Convention, hosted in Waynesville, Missouri July 13 -17, 2015.

The 2015 NSS Convention “Hitchhikers Guide To Missouri Caving” logo includes Missouri cave diving in its design.
