Pond Questions

Hi all,

I'm looking at a potential pond site at the highest point in the property. It's about 80ft uphill from the building site and it will be an excellent gravity fed water source delivering roughly 35psi.

The trouble is that the high point in the property sits on the end of a flat topped hill. The flat top is about 5 acres in area, and I'm wondering if the pond will fill.

Any thoughts? Is this going to be a pond or a crater?

The pond site is the blue dotted line, and the white lines are the property boundary.

Contour lines are 2ft increments.
