you can find kokes flatlining this early, later in the season after the water warms they will be down further and easier reached with a downrigger.
there may have been a bass tourney, it seems like this time last year I had the same problem with a loaded parking lot. and if they were bass boats, thats probably why you didn't see them on the lake, they fish the arms a lot up the santiam. away from the main lake where people troll for kokes. But It may just be because of the size of the lake. I have been up there memorial day weekend, when all the parking was full, but once you get on the lake, theres plenty of room. I love that res. Im starting to drool, I better get off here, Brian
