yeah, the pond has THOUSANDS of minnows in it, as well as tadpoles, painted turtles, snapping turtles, leeches, and we get a visit from many geese and Blue Herons every year. as well, it was stocked with Bass just last year. we have yet to try to catch any though.
but you're right. the entire backyard turns into a veritable mosquito farm once it gets warmer.
