What Would Be Normal Rate of Surface Fall?

[Davy]

I have recently moved into a house and have found a butyl-lined pond at the
bottom of the garden with very little water in it. I have filled it but
find that the water level is falling. Not being experienced with ponds I
cannot tell if this is normal evaporation or a leak.

What rate of surface level fall would you expect to be normal for a pond
that is:
- in Wiltshire in England
- in shade
- about 4 square meters surface area
- no plants

thanks

Not much currently, assuming you're coolish, occasional rain right now? Is
there a waterfall? Moving water of any kind?

If no moving water. Take a bucket and set it on something in the pond, fill
it to the level the pond is at. If the water in the pond, goes below the
level of the bucket, you've got a leak. ~ jan

I'm in the USA and when the weather is damp here, there is little
evaporation. In dryer sunny breezy weather it can be an inch a day. But
this also depends on what's running in the ponds. A water fall or spray
fountain may cause more evaporation.

Jan,

what a nice simple test; obvious when you are told. No fountain or plants
growing out of the water so should work. I will try it now.

Come to think about it, it does fall in that KISS category doesn't it? ;o}
I'm really hoping you find it is only evaporation. ~ jan
