Ok, I'm planning a large (for my backyard) formal pond. It will ideally be planted with aquatic plants like lilly pads, duck weed, some reeds and have various small fish in it (no koi or carp, no catfish-probably just mosquito fish, feeder goldfish, maybe one or two bass). I have 5 ducks and a goose and I was wondering if allowing them a weekly visit would devestate the pond once its established. Ideally I want them to regulate the duck weed and other floating plants & I'll work with different types of plantings to figure out which ones they don't like. I'll have a heavy duty filtration system for the whole thing with a waterfall and maybe a fountain in the middle. The overall dimensions for my raised pond will be 3 feet deep (1 foot in ground, 2 feet raised) by 14 feet long and irregularly oval with an average width of 4 feet. Does anybody have experience with ducks/geese and formal aquatic plants like lily pads, reeds, floating and submerged plants? Do they rip them out or just eat them in place &/or tear them up a little? Has anyone successfully (or even attempted) dividing a pond to protect an area from ducks, and if so what was used?
