Two years later:
The top soil has been removed and old dry stream channel and all suspicious areas have been sealed with 1-2 foot of red clay from materials taken on site and bo magged/compacted in.
I have been told by the NRCS that they have discovered that their is a large cave within .5 miles from my lake, which spews forth 500 gallons per minute during this drought and empties into a 2 acre lake below. I knew of the lake, but thought it was fed by a smaller spring. The cave's mouth has an elevation is some 60 below the base of my pond, and again, it's some.5 mile away. I have searched it's history. The cave has five channels, and is 20+- wide at the mouth. For those of you who may recall, I had started a thread about witching a 20' wide void or cavern(at the time I thought underground creek) under a sinkhole which lead for several thousand feet getting within 200-300 feet of my pond/lake. It may be one of the 5 cave channels. Whether water is in it is not known, but it is likely that it is, and it is the source of my small spring, which is now on the surface of the pond bottom, rather than disappearing. I hope the clay has separated it, as there is no question that hydrolically the water head is below the lake.
At any rate, the saga goes on. One day, when I get time, I'm going to tell the whole story.
