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
there is no water near the ground level anywhere. Though the local water
table is very very low, due to no rain for the past 45 days.

If you are leaking into the ground around the pond, you'd be hard pressed to
detect it, especially at such low levels. If you believe the stream is the
culprit, your best bet is to shut it down for a few days, and see if you
still leak. If you don't leak, you can be sure it's the stream.
