Evaporation rate guesses
(bob carwell) wrote in message om...
Could somebody at least give me some very, VERY rough guesses as to on
average how much water I might have to replace due to evaporation for
a pond. I have seen threads and understand it is very complex with
all sorts of equations, variables of relative humidity, amount of
splashing, surface area, etc., etc. but I just need to get a rough
handle on how ambitious to get. Some anecdotal real examples would be
helpful. I'm currently looking at maybe a 10x15x2 ft. pond with
perhaps a run of 75 ft. of water effects (mostly a small stream with a
few little waterfalls) and a recirculating tank below. I'm in Austin,
TX, and the water would get maybe 60 % sun during the day. I am
clueless whether I'm looking at 10 gallons/month or 1000 or whatever..
Thanks.
Yikes !!! Thank you all for replying with very valuable
information. Exactly what I was looking for to get me in the
ballpark, and I think I will have to consider scaling back some-
perhaps foregoing the pond with covered reservoir and collection tanks
since surface area appears to be the key or maybe if I stay with a
non-organic pond, some sort of cover on it like a swimming pool cover
during the hot days, placing it all in shade, or being satisfied with
the running water effects of the stream and waterfalls. We're coming
up on a week of 100+ degrees here in Austin. Again, very valuable
data points. Thanks !
