Winterizing pond plants

Well, the weathers getting colder and i need to figure out what im doing with my marginal pond plants. I have the following plants:
Arrowhead
Water Spearmint
Dwarf Horsetail
Horsetail
Darf Cattail
Water Iris

So what sould i do with these as in pruning for the season? Any help would be great

Much of them are designed to survive winter without any additional care. IF they're hardy in your zone I wouldn't worry too much about them.
