Fred, can you drop a bubbler under your dock to keep the water circulating so the ice doesn't form there? Or are those only good for really small bodies of water?
I have seen bubblers on Lakes or even in marina's but I don't think they would work on a river.
The water is flowing again along our sea wall, but the rest of the river is iced up. It is raining and the weather is supposed to go up to 40 or more degrees Friday and Saturday.
If the major flow occurs during daylight hours, I'll take a vid ad post a link to it here.
