It was a 2#.# ac tract that fronts on the lake... ( they had the acreage as 2#.###. - basically a square- (yeah that's how we do things here... 😉 )
The side opposite the lake was 10##.## feet long, with nearly parallel side lines...
the lake frontage was "surveyed" as being a contour- and returned as 52 courses... bearings recorded to the nearest second, distances to the hundredth. longest course was 57.30 feet shortest was 2.86 feet. 7 courses less than 9 feet long, 6 courses greater than 40 feet long..... none of the short courses were the result of being truncated by a sideline.....

any guesses on the survey technique used.....

"Exactomundo Surveying strikes again....

lol, that is some exact contour surveying.

I had one of those a couple of years ago. Lucky for me it was done some years before and I was just splitting it, so the old guy back in the 70's had actually run the contour line off the dam spillway elevation, and set pins, made it easy. Now you know what happened,,,,,,,,,,,,,,,

Makes you want to take these guys out with a level and rod and make them do it the old way,,,,,,,,,,,,,,,,,

We did some tracts for a large reservoir expansion, another surveyor set pins on the design elevation, and then we tied into them and created new tracts.

There were many miles of new lines run on that elevation, I doubt there were more than a couple of hundred points for all those miles;-)

Every lake contour boundary I've followed was based upon an elevation at the dam or spillway.
