Dunnings Spring Decorah Iowa
 
We were on our way out to Coldwater cave and I wanted to stop off at a couple springs to see if they are potential dives that can be pushed.  Dunnings Spring is in Cordora IA. Just outside the city limits. There is a impressive waterfall resurgence coming out of this cave with year round moss growing on the submerged rocks and a walkway leading to the resurgence. I get up to the cave entrance and the water was crystal clear with passages that look like it goes.

I donned my gear and proceed to push on into this underwater cave.  About 20ft into the passage I notice a breakdown restriction that I proceed to maneuver around this pile of boulders and come up to another restriction.

This one is quite tight and I was not able to work my way through this restriction without damaging my gear so I ended the dive and came back out.

I referred my study to a caver at Coldwater cave and he described to me that a cave diver in the 1970s tried the same thing and was not able to proceed where I was restricted.  The cave apparently is a relief for another cave in the area that has been badly damaged by a nearby quarry and access to that cave is closed.

Even though the water is crystal clear and nice a follow-up dive will not be necessary as we will not be able to get access to the complete system or we will have to micro shave the breakdown restriction which will also not happen due to the city’s risk assessment. Until the future, whatever lies beyond the Dunnings spring restriction will remain a mystery in the cold water climate of Decorah Iowa.
