The yellow crayon mark indicates the surveyor’s notch for the court ordered maximum elevation of Little Platte Lake - 586.7 feet above sea level.
For easier visual reference, note that 1.80 on the scale is the same height as the surveyor’s notch.
One-tenth difference on the scale is equal to 1¼ " on a ruler.
Examples: If the water level is at 1.70 the lake level is 1¼" below the court ordered level.
If the water level is at 1.60 the lake level is 2 ½ " below the court ordered level.
