After reading Drawout's post I think they were looking for ducks.

When they're doing that you can present baits to them right on the surface and catch a ton of fish. The rig I use for this type of fishing is by tying a heavy leader about 50 to 60 lb test onto my mainline with an albright knot so that the knot will go through my levelwinds and then put a bead then swivel then another bead and then a teamcatfish bumper on then another bead then tie a stop knot about a foot above the end of the leader. I use a short dropper loop knot for this then cut the dropper loop off leaving about 1/4 inch tag ends sticking out just to get the dropper loop out of the way. I use this knot so that when I get a fish on the swivel will slide down the line and stop at that knot. tie the sinker on bottom. then tie about a foot and a half hook leader on the swivel and use a 5\0 circle hook and float on the hook leader so that when this rig hits the water the float will send the baited hook to the surface. This rig is deadly when you see most fish in the area suspended and surfacing.

I also use two 3oz float rigs with 8 inch hook leaders too when this is happening but you can only use a couple of floats if there's wind or current as they'll all end up drifting together ... the rig described above stays put until you get a fish on.

This seems great but I am having a hard time picturing it. Do you have a photo of this rig?
