What to do about Canada Geese

[cwt]

An old cranky retiree (like my dad, who has a 1/2 acre pond) will thoroughly deter most Canada geese... not in a friendly way, but at least he doesn't shoot them. Mostly just lights off firecrackers and gets up in their grill. [edit: the geese don't bother the fish... but the blue herons that occasionally show up will go through a LOT of fish if not kept in check]

Whitedevil mentions netting the pond... at my place of work, they run cords across the pond in a criss-cross fashion; not really a 'net', just enough to keep birds from landing on the pond. The geese just mate and nest in the landscaping instead ;0
