Enjoyed the morning Bob and I spent talking and walking. Learned a lot. Following his advice, I contacted a local dozer/backhoe operator who just happened to have grown up on this specific piece of property, 30 - 40 years ago. He and his son came out and dug 9 new holes as deep as 12', 6 close to, but not in the creek bottoms. Three back in the dam area. Found quite a bit of clay in 8 of them. One was primarily sand, but 15 feet away in another was a lot of clay. The clay was grayish/white in most holes and pink/orange in a few others. Plan to get it analyzed at a different lab than the one used the 1st time. Paid $1100 for the 1st digging and testing. Paid $250 for this digging and got some road work thrown in to boot. Live and learn.
Still haven't found a forester, but have some feelers out. I've asked NRCS to determine the dam size and location. They balked at a project this big, but finally agreed to "see what they could come up with."
If you know of a good lab or forester, please email me. Still moving forward.
