Should I keep my Pond in Carlisle PA running all winter?

This is a question I get asked all the time.  Their is no right answer for ponds in Carlisle PA, some people like to shut them down and some like to keep them running.  The pro's of keeping it running, it will help put dissolved oxygen back in the pond for your fish and help keep a hole in the ice.  The best thing is it will make amazing ice sculptures and if you have lights these look amazing.  The cons of keep it running you will have to make shore the water level stay up and that the ice in your stream dose not make the water run out of the pond or stream.
