The Ozark Cave Diving Alliance (OCDA) is a 501(c)3 non-profit corporation. Our safety and conservation oriented group of underwater cave explorers use their skills to assist in education, research, and scientific documentation of underwater conduits and sumped cave passages in the Midwest area. Some organizations we have collaborated with in the past include the Missouri Department of Conservation, the National Park Service, the United States Geological Survey, and several private landowners. The OCDA stands ready to assist in any endeavor to promote conservation, education, or exploration of underwater cave systems in the Ozarks.
