Believe it or not, 150 is a cool level in a play boat for pine and 1 thru 5. It has a creek boating feel and things can get interesting. However, it is good at any level. Whoever it was that proposed the Ark didn't deserve "Classic" status must have a broken helment from the dainbramage he's suffered. One simply need look upstream from the bridge at #4 during low water to see the classic boulder placements. Then come back and see it exploding in white at 2300.
Pine and the Numbers were a gas yesterday. Slicing slalom moves, catching every micro eddy to hone your skills and creativity, all the way down is a blast. 2300 cfs is when Granite thru 6 exudes it's truest Classic status. 4800 in Pine Creek is a mile of white line fever that will tied you over for years between those kinds of infrequent flows anymore. (Though, the North Fork of the Payette at 1800 is the place to find 16 miles of that kind of rush every year if desired.) To top it all off, the weather is often fantastic over here. This last weekend might possibly have been unbeatable, though we'll likely see many more of those days this summer.
