There's a lot of fatalities when people jump in above a dam to rescue their dog, only to get swept over and drown. In some cases the bodies circulate below the dam if decomposition gases produce enough buoyancy. Or the body surfaces miles downriver. In all but one case I know of, the dog gets out on its own. Sadly it's taken decades and usually repeated fatalities to prod authorities into action. Dynamite does the job. Where the dam is still needed you can raise the downstream riverbed with rocks 4+ feet in diameter and end up with a runnable low hazard rapid.
