My annual fishing/camping trip to the lower Yak Canyon has had multiple hurdles thrown at it this year, but it looks like I can sneak away for a couple days next week. For the 10 years I've lived in Washington I usually fish and float between Umtanum access and Big Pine (where I am usually camped). Think I know this section pretty well. This year I am staying in Ellensburg and thinking I should get to know the river above the canyon and the upper canyon better. I'm not looking for anyone's fishing hole, but rather river information. I will be floating a 1-man pontoon and am looking for info on anything I should know about the river conditions (e.g., obstructions, tricky currrents, etc.) from KOA down to Umtanum. I floated with Steve Joyce a few years ago from the KOA and there was a pretty nasty sweeper that he navigated expertly, of course, but I'm sure I would not have done so well in my small craft. Any cautionary advice will be greatly appreciated. Thanks.
