I'm not encouraged by the way each draw runs up onto the neighboring properties. To get any kind of pond depth, you will either be into the bottom land or backing up water onto your neighbors.
The creek that runs thru your property looks like it can be a wildcat when it rains hard. I'm gonna guess that you might be in for issues by gettin' too close to it. Moving uphill puts you into your neighbor's. You can't dam up their draws unless you can provide a drainage system for each; big engineering job.
