I live 15 mins from the 322 bridge and hardly fish it...but when I have, I went at night with crawlers and chicken liver for catfish around the docks..usually can catch some nice channel cats.
As for bass..I would target downed trees and deadfalls and also go up into the coves. Largemouth and Rock bass were the main catches. I did catch a sub-legal walleye on a Strike King KVD square bill crank over by the swimmers rock at Toby this past May. Guys will troll for walleyes and musky but I don't waste time on that. Plus there always seems to be alot of debris floating in the river..the speed boats and jet ski's churn it up alot on the weekends and plus the dam holds a alot of stuff back too.
All in all I dont like fishing the Piney Reservoir section of the Clarion..would much rather go up to the Cooks Forest section for Smallmouth bass or head west to French Creek or Allegheny River which is also pretty close to me
