Leak in pond liner

we have just replaced our pond liner and are surprised how quickly the water level went down. It was hot and windy yesterday but it must have gone down about 5 cm in about 12 hours. It had gone down more by this morning. we have put more water in and marked the level so fingers crossed. But what is a reasonable amount of evaporation we could expect. image Jan

    Can't really answer that because it depends how deep it is - a wide shallow pond will evaporate fast in this weather, a deeper one less so. Don't top it up, keep an eye and see if it seems to keep going steadily (leaking) or to stop some days and speed up others (evaporating).

    It is possible to fix a leak in a flexible liner - actually it's very easy. You can buy rolls of tape to suit all types pretty cheaply and they work well. The difficult part is finding the hole. So if it is leaking you need to let it leak until it stops and then look around the water line for a hole or tear.

    Is there a fountain in it?  Spraying water into the air will make it evaporate faster.  You could try turning off the fountain and see if the loss slows down.

    I have found my garden ponds (various property's i have lived in over the years) of various sizes and depths have gone through this fluctuation sometimes for no rhyme or reason. Keep a close check on it and if you do have a "hole" in your liner it will be consistent on duller days (we have plenty of those) throughout the seasons !! 5cm is not a lot even on relativley (250 gallon) small ponds ?

    Many thanks for all the advice. The water level has stayed the same today so hopefully alls well.image
