Getting Ready for Winter

Anyone else thinking about it?

I am in MD, near Baltimore. It's been too cold to swim for weeks now, so the
pool is getting closed this weekend. I was thinking of moving my filter
plants to the main pond, so I could drain, and clean the filter. I figure
then I can let the stream dry up so I can patch the leak. After I do all
that, I'll probably leave the filter empty for the winter and call the pond
ready for the winter.

Too early?
