what is a acceptable amount of water loss--due to evaporation etc?
Trying to figure out if I have a leak....

Pond is in So Cal, where we get hot days over 98 and cold nights below
70, so the ponds goes through some big temp swings. ANyway

the pond has a 3 to 4ft waterfall into a 5 by 4 2ft deep pond that
drops into a 5 ft, few inch deep stream. the water then ends in the
final pond about 11ft by 8, witha depth from 2ft to a bog shelf around
9 inches deep! anyway windering how much water people loss and how
often they top off their pond? It seems I have to do it every other
day, as I lose about a inch or so in that time in the bottom pond only!

Sounds normal to me, considering you waterfalls & streams. A still pool
can
lose anywhere up to 1/4-1/2" per day, more when heavily planted. ~ jan

I agree it's normal - and you always only lose it from the bottom pond
because the upper pond is always going to be filled to the level of its
overflow.
