They don't all spawn at the same time. Some fish might have gotten washed out and some have already spawned. The flooded cover should really help the fry.
It also makes it harder for guys like me to sight em, well, because I can't see em! Hah.
Knowing where a few beds were right before the hard rain and wind, I went to them a day or two after. Water was HORRIBLE muddy. Still yanked em up. I say the water clarity doesn't effect the spawn in a negative way. In fact, with guys like me, and other bed predators, I guess it would have a few more positives.
