Evaporation rate guesses

Yes, sounds reasonable. Here in Memphis, TN with about 120 square feet pond
area, I lose about an inch a week, up to 1 1/2" per week during hot weather
and running the splashy 3 ft. ledgy waterfall, or about 70-80 gallons to 120
or so. You might try not running the waterfalls for a bit and see how much
difference, if any, that makes.

I thought that I'd chip in here on this. We just built a 7000 gallon
pond
with two waterfalls, one that splashes a lot (but not much leaves the
pond)
with an upper pond of 8x10 ft (more or less) and then a ledge waterfall to
a lower pond that is 13.5' x 14.5'. It appears that I'm losing about an
inch every 3-4 days which is about 172 gallons. If I have any leaks, I'll
never know because the main drain is a three inch pipe that is under the
four foot deep concrete main pond - I'll never see that space!

Does this rate seem reasonable? I'm in Colorado where the average
relative
humidity is less than 20% and I have very little cover for the water (it
is
new) and the wind is unblocked by trees.

What is the consensus for my losses?
