| In
April 2000 the Ozark Cave Diving Alliance was requested to search for a
spring within the muddy waters of Lake of the Ozarks in central Missouri.
Property owner Dave Dodson was interested in finding the exact location
of the spring and documenting possible exploration. Team members
coordinated with Dodson and the search began alongside a local boat dock
located near lake mile marker 38.
Conditions were very poor with visibility at 1 foot, water temperature
at 50F, and a good deal of fishing line, dock cables, cedar trees, and
years of trash within the search area. After evaluating the search site,
team members would employ standard public safety diving search
procedures to maximize safety. This meant one diver tethered by line to
the surface (line tender), a fully rigged/ready on-line safety diver,
and surface manager for dive time and accounting. Bottom time for each
search was limited to 15 minutes.
The spring was finally located at 55' alongside the bluff near the
boat dock and more dives followed to clear nearly 70 years worth of
trash from the spring opening. Clearing much of the debris, the spring
opening was finally visible. A thorough examination of the spring
revealed the opening height at 3 to 10 inches, a width of 10 feet, and a
steep 45 degree entry angle. Water at the spring opening was noticeably
warmer than the lake water and visibility inside appeared to be around
20'.
Follow-up dives were conducted to video the spring for owner Dave
Dodson, however, due to the restrictive nature of the opening, further
exploration was suspended.
