Information Request: Source of Historic Aerials - from 20-40 yrs ago
I am working on a claim against a neighbor, rumor has it he moved a lake (yes, moved a lake) 30 years ago from his property to an adjacent property to the south of his so he could then develop his site. The problem is, the roads and drain lines built 50 years ago drained into that lake and now he is claiming the existing drainage is damaging his property. My hope is we can produce an aerial showing the lake before / after the move. I have seen old aerials in appraisals dating back to the 50's - anyone of source for these historic aerials? Software, website, or perhaps a surveyor?

For any wondering, Google Earth has already been checked.
