I have a question...do you think there is there anything wrong with covering my pond with clear plastic for the winter?

I taped together a few sheets of painter's plastic and anchored it over the pond for our recent set of freezing nights. I placed 2x4s across the pond to hold it up over the center and then put bricks and rocks on it to secure it down. The plastic is raised about 3-4" above the surface of the water. I wonder if this will create any negative side effects for the fish or my plants?
