In October 2014, Dam Seepage was discovered in the earthen section of Boone Dam. The seepage is a cause of sink holes and irregular bedrock known as "karst", which form voids with erosion ... As a result, TVA was forced into draining Boone Lake to an extreme low level for safety reasons. A 3-stage plan is in place but will take 5-7 years and $200-300 million to have a permanent fix. Many people are discouraged about the news, don't blame them, but it is what it is.... A small group of us are throwing out a silver lining here. Placing some here and there, on or around some new acreage that will be available now for at least a half a decade. When the Lake is back in working order, we can archive or leave them for people to dive after :) An invitation is extended to all area cachers to contribute to the series in new hides anywhere on the exposed acreage, just throw in the next number of the series to keep it rolling.

#40

 This hide is on the upper reaches of what used to be Boone Lake. It is a boat required cache on one of a pair of islands that will be under water once the dam construction is completed. Of course, that isn't due to happen for three to five more years, so you have plenty of time to come find this cache. 

The river is pretty shallow here. You will probably want to pass the islands on river right, and then paddle back up to the island that is on river left.

I checked out the other island first, but it appears to be a natural duck blind for hunters. You will want to proceed with caution if you are searching for this hide during duck hunting season.
