I have a question about pond/stream evaporation for any seasoned pond
owners out there.

My pond is about 23'x23'x24 inches deep with a 63 foot stream. The width
of the water in the stream is about 14 inches. The stream bed is small
river pebbles.

Temps have been in the 70-80's in the day and 50's at night with a low-med
humidity. No rain during this period

I don't understand what the water level in the pond goes down about
1/4-1/2
inch in about 2 days. I had thought I had a leak, but now not sure, since

In low humidity, and slightly higher temperatures, I wouldn't be at all
surprised with a 1/2" drop in _one_ day, so your numbers aren't at all out
of line. However, check for splashing, and any point where
outside-the-pond plants or sod could be wicking water out of the pond.
