I just built a dock in my pond and I want to mount a scale so I can see at a glance how high above or below normal the water level is. I am sure someone makes a plastic board with durable numbers that I can permanently mount so I can see the change but I cannot find one on line. The ones I found only have a counting scale and I was hoping to get one with a zero point which I can mount just as water is flowing out over the dam and from then on have + numbers for above normal and - numbers for below normal.

Any suggestions for either DIY or a source?
