Rainman I believe we're in agreement

The problem I have is that I followed the gravel up the ravine behind the dam and hit the rock shelf
The layer of gravel is under the shelf
So I want to bust through and continue sealing it until i'm above the water level

The reason I installed the pipe was
1) I couldn't break through the rock so
2) I figured that I can monitor the water movement by installing the pipe

So now that I have a constant flow of water I will pull the pipe out and continue sealing the gravel way past the water level

I made a little diagram hope this makes sense to you
