Free: Contests & Raffles.
Pretty much any open spots u can find on the lower yak will hold some. Off the Columbia in the tricities or down by Patterson and Plymouth hold smallies too in rocky areas in the sloughs. I tend to use tube jigs most of the time fishing those areas. Try not to use a light rod. I use my light rod and reel setup I use for crappie but have lost some nice sized catfish fishing for smallies on the lower yak off the bank.
