We've been having some problems with our pond recently, and now that we've figured it out I thought I'd share it here!
Over the past few weeks we've had a lot of rain here in the UK, but weirdly we kept seeing dramatic water loss in our pond. Some mornings we would look out and see that almost half of the water had gone. In the end we thought that we had a leak, which was quite concerning as it would mean disassembling the pond to fix it. We were regularly filling up the pond from our water butt, but it was getting through so much that we couldn't keep up - despite all the rain. We have had drops in the water level before, but I always thought it was due to evaporation as the drop was not at a steady rate.
A few days ago we took out the water iris plants and took off the net to see if we could spy any damage to the liner... we left the pond like that after topping it up, and the next day saw that the water level had not dropped... interesting. We put the plants back in, and the next day it was still fine...
Turns out that the problems were caused by the net!

Our fountain comes up through the middle of the net, and so it would appear that some of the water was evaporating off the net instead of dropping back into the pond.
I'm just so surprised that such a large amount of water could be lost due to evaporation from such a small pond!
