Flooding and fishing?

[UTMike]

So I'm curious if fish migrate into flooded areas when water rises. I love fishing the bear river but with the recent flooding it makes accessing the main Chanel tough. So I'm curious. Do fish migrate in to the flooded areas around the river? Areas that are typically dry land.
Never really thought about it so I figured I'd see what you all think.

This may not relate to your question, but a few years ago I actually saw carp and catfish swim across the road to the refuge!
There might have been 5 or 6 inches of water flowing over the road at the time. I do know that fish can sense rising and falling water levels and will vacate an area id they sense falling water. FWIW
