Alley Spring

 Ranked the 7th largest spring in Missouri, Alley Spring is located approximately 6 miles west of Eminence in Shannon County, Missouri. This spring rises within the National Ozark Scenic Riverways and is just north of the Jack Fork River. Diving in the spring is by research permit only.

 In mid-2000 the United States Geological Survey requested the assistance of the OCDA to obtain scientific data from within Alley Spring. To date the team has been able to survey/map several thousand feet of passage, collect rock and sediment samples, and take video and photographs within the system. Just under 3000' of the system has been surveyed with an average depth of 155'. Outbound divers encounter a rapid flyover point in the system where divers come out of 150' and rapidly cross the Kentucky Peaks area at 60' before descending again to 145'. Exploration continues although this system is normally plagued with poor visibility and high flow.

  Ozarks Watch Video Magazine hosted by Jim Baker filmed an article on the OCDA and the Alley Spring project in May 2004 to be shown several times on Ozark Public Television in Springfield, Mo.
