Waterfalls and winter

[sissy]

You have to factor in wind also in a waterfall .I live in VA near the NC border and may waterfall is exposed to winds and the wind blows the water all over and as it freezes the water ends up following the frozen water and finds it's way out of the pond .So my hoses get diverted to the pond only .It is not worth the risk to me .I had it happen to me the 2010 winter and if I had not caught it my fish would have frozen to death .There was maybe a foot of water and it was around 1 am in the morning with wind and snow and there I was running hoses from the basement and even from inside the house .The liner had bubbled up because all the water had rum behind the liner and i was worried it would crack the liner .A year later sure enough I had to replace the liner and last march something chewed through my liner and again had to replace the liner .It was a hard hit when liners are around 300 dollars for a 20 x25 liner in 45 mil epdm .Ce on here had the same problem happen to her

I have kept the waterfall running all winter too. The previous owners of our house said they had the waterfall on all last winter (which was a record-breaker when it came to cold/snow), and as long as they had the de-icers by the skimmer box, they had no issues at all with the waterfall completely freezing. Right now there is sort of a shell of ice above the waterfall stones, but the water is flowing freely beneath it. I just keep an eye out for any new ice formations that look like they could dam up and/or redirect the water flow by the waterfall or along the stream that dumps into the pond itself--so far so good.
