Tilapia, as well as most species of fish, will exit ponds during high flows. In fact, on two separate lakes we stocked in Kansas this year with tilapia, we have observed tilapia in the plunge pools which are fed by the emergency spillways. On some of the smaller ponds we stocked in the city that have huge watersheds, they are all but gone. We've had near record rainfalls so it is what it is.
Over the years, I've personally witnessed bass, bluegill, shiners, etc strewn across pastures after heavy rainfalls.
