There is Management on site, and dive shop concession on site with refreshments. Blue Hole water clarity and depth are among the features that enhance the training and ability to communicate during exercises to improve diving skills.
Fishing is not permitted at Blue Hole. Swimmers, Pets, or Children are allowed and fees may apply. Blue Hole is a well maintained and landscaped facility dedicated to Scuba Diving Training. Open Water, Advanced Open Water, Rescue, Dive Master, and Diving Instructor Training can be completed at Blue Hole. Rescue, Law Enforcement, College, and Military groups regularly utilize the Lake’s facilities. A variety of aquatic life flourishes in the Lake. No fishing, or use other than Scuba Diving, free diving or recreational swimming. Training is allowed at the Blue Hole. Recreational swimming at Blue Hole is by permit only and scheduled hours for swimming are posted. Lake management seeks to maintain a pristine natural lake environment and has taken measures to channel surface runoff water from polluting the Lake.
Water Conditions: You can dive the Blue Hole year-round (winter is actually the busiest season), thanks to the constant spring flow that keeps the water temperature at a stable 61 degrees. A 7-mil wetsuit is considered the minimum thermal protection. Visibility is a consistent 100 feet.
Dive Equipment and Air: Santa Rosa Dive Center, (575) 472-3370 is located next to the Blue Hole, and is open on Saturdays and Sundays from 8 a.m. until the last diver is served. The shop rents gear, scuba gear, diving suit, diving goggles, tanks and offers air fills, but does not provide instruction. Shop owner Stella Salazar will also open on weekdays by appointment for certified divers and groups if you call ahead.
For More Info: Contact the Santa Rosa Visitor Center at (575) 472-3763.
Geology: Blue Hole and the Santa Rosa area system of collapsed sink hole or cenote lakes is a true geological phenomenon. It was formed by estimates anywhere from 20,000 to 100,000 to 300,000 years ago by water erosion action in both subterranean and rain, watershed flows and surface water. The collapse of the “Santa Rosa Sink” area took place in two basic types of geological events; some of the collapse and formation of the “Santa Rosa Sink” were in sudden drops of a number of feet per event; some of the collapse events were immeasurable or unfelt by humans if there were any at the time, at centimeters or inches per year.
Blue Hole is a geological phenomenon consisting of a large water filled sinkhole which is a natural spring fed lake with an outflow of 3,000 gallons a minute. Blue Hole is one of 7 such sinkhole lakes fed by an underground water supply that is no doubt connected through water-filled caverns underneath. Other lakes include Hidden Lake, Twin Lakes, Perch Lake, Bass Lake, Post Lake or Swan Lake, and Rock Lake.
The Santa Rosa Sink was formed by water seepage and erosion over millions of years slowly forming a large basin and wetlands. Subsequent collapse of geological strata or karsts weakened and dissolved by constant water action formed the artesian spring well that now provides the spectacular setting for the park. Sinkholes, common in the area result from the dynamic combination of water erosion below and standing water pressure from rains or springs from above resulting in a large sinkhole or cenote, a water-filled geological phenomenon.
