Welcome to the Forum! You've got some good altitude for a lowlife!! \:D \:D I really like your aerial photos! Otto and others will help a lot with your questions. It's nice to see someone thinking ahead for their pond work. Too many of us found this great site AFTER we built problem ponds. You will definately want one of Bob Lusk's books--"A Perfect Pond-Want One?". Great pond info in it!

I know nothing of soils, but the first thing I wondered is if the pond draining your new property will be badly impacted from the soil runoff. You may want to get some grass and haybales out there in front of the culvert ASAP so the new neighbor doesn't get ticked off. You'll also want a pretty good set-back from your property lines and the roadway easement.

Again, welcome to the forum!
