Is it bad that I dammed up a blue dotted line?
I used a similar map, called OnX hunting app shows all the topo maps, actually appears to be the exact same map, thats how I calculated my approx acreage that my finished pond should be.
That app will actually let you draw and mark on it and measure an area inside your drawing. Its also how I found a couple of my property lines that were not marked very well, just the corner pins, so finding your property lines thru half a mile of woods isnt easy, but with a little signal it will point you almost to the exact property line, withing 20' with good signal but within 40' with sketchy service
