For those of you who receive significant snow in the winter, I'm wondering how you protect your pond from predators during the winter? I have to leave my pond netted 24/7, and I am concerned about accumulating snow weighing down the net into the water and/or freezing into the water. I've had one raccoon attack, and it was devastating, so I do not want to take the net off. I live in zone 5 and in a "lake effect snow belt," so our annual snowfall averages around 200"! We also receive howling winds...
