I was a long time user/abuser of this site, but left for a while. Now i'm back.
My question is where the fish go in winter. I live in Clearfield on the banks of the west branch, it's 2 blocks from my house. So i get to know the river pretty good. In the warmer months i can find fish at will, there will be carp swimming up and down in schools and alone. rock bass, smallies, perch, trout, and a pickerel or two. where i fish at is 8-10 ft deep in a river that in most places you can wade and not get your pants wet, has a small spring coming down out of the mountain, works great in the summer as trout stack up just like on trout run in erie.
 it's now winter and i haven't seen a fish or caught one since 10-14-2015. this is not the first time i've seen this as it seems to happen every year.
 My theories are 1. for last 2 years we've been getting alot of rain in bunches, where it slows before the lowhead dam,below where i fish, fills up with sediment. where once was cobble is now grit.
                        2.if it's winter and the water temp is in the high 30's where i fish should be the place to go, deep and with a spring to provide warmer water. 
 anybody have anything?

Florida.

Sounds like if its 8 to 10 thats getting a little shallow for the warmer fish.

They're on their way back!! Too cold down south!

They usually head for deeper water.  Just because you're not catching them though doesn't mean they aren't there.  Warmwater fish like bass/carp will probably hold tight to the bottom and become inactive.
