With the liner it would be mostly surface runoff.
In addition to that one contractor brought up the possibility of some drain lines from other areas to catch surface and groundwater to supplement.

There are a couple ponds around that I know of . I'll check the satellite image for more. Good idea

Right now I'm leaning towards renting an excavator. I need a bunch of trees taken down and the cost to pay someone is almost as much as a weeks rental. Day or two taking trees down then dig a big pit at the lowest point and see if it stays at an acceptable level year round.
Neighbor needs some work done too so that could help pay the rental also.

Thanks for your input.
