If they're little pencil shaped fish, leaping out of the water, it could be Brook Silversides. They will leap out of the water for any number of reasons, but usually when spooked by a predator fish's presence or to grab a gnat or skeeter that's flying close to the surface of the water.
I wouldn't think baby Asian Carp would jump out of the water, unless they're the species that jumps when startled by a running outboard motor. Their food source is IN the water (plankton) so they have no reason to leave their water world.
Small Shad will "flick/flit" and splash the surface, but don't usually actually leap out of the water.
From your description of them being scattered all about ... my money is on the Silversides being what you're seeing.

The description of their behavior is still a good one regardless of the species.
