I wouldn't trust the ice, I was ice fishing a few years back and the whole pond cracked, my two friends made it off me being the lightest i went for the tackle and our blue gills and the couple catfish that we had on the ice. I managed to get all the gear and fish off the ice right as i went to get off the block I was on began to slide under another block. Well i made a jump for it and got my legs soak n wet! burrr it was cold but at least no one was sucked under and didn't have to replace expensive ice fishing gear lol. ever since then I wont go on ice unless I drill and it is at least 6" even then I will feel unsafe I like to wait for 8 to 10 inches of ice, but not sure if Oregon stays that cold for ponds to get that thick?
