## Main Question or Discussion Point

Not sure where this posts needs to go, as I am not familiar with engineering, so if it needs moved, please do so.

I build decorative ponds, and one of the conversations I end up with is the evaporation rate of the water in a pond setting. I do know there are formulas out there on the rate of water that is not moving, but in my case there are several wild cards to add to the mix.

Case in point.

Pond has aprox 560 SF of surface area. It has a depth of 6 feet. There is a major water fall that is 6 feet wide, three feet long, with 22,000 gallons of water flowing over it per hour. That water flows to an upper pond, then into the lower pond via two more falls, aprox 3 feet wide and two feet long each.

Then there is a skimmer return that roils the water surface and keeps it in motion, the flow of which is 3800 gallons per hour.

I am aware of many of the situations that affect evaporation rates. Could there be a formula that I could use that would give me at least a rough idea of what to expect?

While not uneducated, I am somewhat math challenged (wish like heck I had paid more attention in high school and college!)

Thank you in advance!
