No power out there, eh?
Then I suggest you make the pond as big
as you can afford. Stock it very lightly with a some
rosie red minnows or use mosquito dunks to keep the mosquito larvae down. No
lilies in the pond, unless you remove them before winter (plant in pots). That
way you won't have the problem with an over abundance of rotting vegetation and
fish waste to produce toxic gasses.
Any severe winter is going to cause aquatic animal deaths but the cleaner the
pond is going into the winter the better the critters will do who spend the
winter under the ice.
Another way is to fill a milk jug with black sand and place a couple of them
around the pond. Works in milder winters.
