Hello paddle people! I live in PDX and have not yet explored the Seattle area. Thinking of coming up this spring for a tour of the class III and IV of the region--maybe a taste of V or I might walk it. Anyway my question has to do with the odds of good flows in the springtime. I realize that we don't even know yet if the La Nina pattern will continue into the spring. What's the optimal time in spring for a planned trip up there, knowing full well that the rains come when they come and I could miss? Thanks.
