There's a stream, class A browns, that I just started learning this year. It's extremely well known and posted about, but I won't name it with this little secret, though if you can figure it out, great. It seriously comes down real quick. Last spring, we had 3+ inches of rain on a Saturday, it flooded Saturday evening, was in prime fishing condition Sunday morning, and was a gettin a little low for my tastes by Sunday afternoon. Urbanized stream, storm drains give you the quickest runoff imaginable. It's a curse overall, but you can use it to your advantage now and then.
Your purely forested streams tend to resist coloring up, and when they do color up, they clear very quick. The water doesn't drop that quick, it just clears that quick. So if you look for the little brookie streams in a forested surrounding, you can find high and clear conditions, which can be good fishing.
And of course, your spring creeks also clean up nicely, if you're close to the source.
Tailwaters are artificial. Under most rain conditions, they usually hold back while everything else is up, and then let it all out as the other streams come down. That's typical, the current situation is anything but typical, as some dams lost the ability to control outflow, and some are desperately trying to get their lakes down to avoid damage to the dam.
The worst case scenario is a large drainage area in farmland. Those streams take forever to clear. Penns is a prime example.
