@cmom Happens here all the time. Only way to keep it from happening is constant watching and removal of debris as it starts to build up. Yes a pain in the hinny!) But one year we where not vigilant and leaves clogged filter/pump and the fish DROWNED!!!! Well about 3/4 of them We have tried to place netting or screen over pond only to have it fall in under weight of falling leaves or blow off in wind.
YESBottom line a nice pond is a lot of work.
