We found a school of BIG smallmouth bass on the Willamette River. It is late February and the air temp is 50-58 degrees. The water is right at 49 degrees and with the right action, you can catch some nice Smallmouth. The Willamette River is a great fishery for Smallmouth Bass. The average fish is 2lbs with big ones pushing 5 and 6 lbs. Check it out.
