The problem with the park is the fact it is HUGE. The western part of the park, like what you mention above, just got off of "Hoot Owl" restrictions which means that the water was so hot that fishing was off limits from 2 pm till midnight.
But, apparently the season is ahead about 2 to 3 weeks, so this may open up some areas on the western side, and that specific stretch has been on my radar. Then again, 1000 other stretches have also been on my radar, so it's not saying much. I'm still debating entering from the South side of the park, and having my way with some of the watersheds in the Cascade Corner.
