I would think it has more light penetration than snow and less then clear ice. Catching any fish close to bottom in the deepest water? If so, oxygen levels are still fine. (Thanks Bill Cody for that common sense tip).

I went out to my pond yesterday and couldn't keep the jumbo perch off the hook. They weren't monsters but were chunky 11 1/2 inch females (don't have any males in the pond as I planted with close to 100 8 inch females last spring). I hope to grow them to 14 or more inches!

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
