Fishing is free across the state of Oregon this weekend. For Saturday and Sunday, no fishing licenses or tags are required to fish, crab or clam, according to the state Department ofFish and Wildlife. This comes after several ponds in the Willamette Valley were stocked for the last time this season. ODFW says fishing for the stocked trout is a good place for beginners to start.
