No I guess I don't know where you are going, are you saying that I will be unable to hold water above this level and will need to dig it all out. No have not actually shot the elevations, just stood on the hill and looked down both sides and they appear very close. The lake does not fluctuate much, is high right now, as every lake is, we are getting rain after rain.
nah, sorry....more like the possibility that the lake and your low spot are both at water table elevation. If this was the case, you may not have any other options than to accept it as your normal pool depth and start digging down to create your pond. At this point, tho, I must admit my inexperience with this geologic hydrology stuff and relent to the wisdom of others within this forum that can guide you further and straighter. When you noted pourous soils, the close proximity of a very large body of water, and the similarity of the water levels within both entities, my water table wheels started turnin'.

Regarding the soils, once again we need others with more experience to chime in. I did not need to lay in a clay liner or do any patching, but others within this forum have and the golden rule seems to be 24" thick. If you intend to process imported high % clay to process/mix with your questionable soils, I need to step back one step with you and ask some of the dirt guys about the practicality of that (particularly considering the size of the area)
