Wow, I didn't know Thomas Creek got a run of Cohos, I've pulled out some nice Cutthroats and Smallmouth in the past few years from Thomas close to Greens Bridge on the Santiam.
Everyone tells me Jordan Bridge (Stayton) is Thomas Creek, but if you go a slight bit upstream from that bridge, it says Jordan Creek. I've seen a few Smallmouth and caught a few Cutthroats, Rainbows, and Squaws under the bridge that everyone jumps from and just slightly upstream from that same bridge.
