So almost 7 years have passed since I started this thread. I have done a LOT of thinking and research. Mr. Otto was was helpful and recommend some others to help me ease my mind about building this pond.
During this time, Texas had one of it worst droughts ever, and this also squelched my progress. Since then, we have had 2 of the wettest years ever.. I am confident that this thing would have filled up if we had the dam in place prior to those wet years.
Looking at these pictures, imagine the lake 12 feet deeper, this is the goal!
