Notes & Directions:		There is a summertime spot on the Sandy River just 15 minutes from downtown Portland Oregon that gives up sweet mysteries and blasts (cool clue spot, too). Take 84 East from Portland to the Lewis and Clark Park exit #18 (just after you pass over the river leaving Troutdale). Take a left at the river and go less than a mile to a stop sign at a bridge. Park next to the bridge and take the trail to the river. The spot comes in at low summer flows (800 cfs,??), when a house size rock on river left forms an pourover shoulder/eddyline for sinkin. There is also a small blast hole just in front of the rock, and another in the pourover as flow comes through the split rock (can clue in with head under). The spot works best at LOW tide if the Columbia is over 9-10 feet at Vancouver, otherwise you don\\t have to worry about the tide. Check this gage for current times: http://tides.willyweather.com/or/multnomah-county/columbia-river--sandy-river-entrance.html There are four hazards here to watch out for: 1) check for large trees that may wedge in the eddy as flows recede; 2) when the salmon and steelhead are running, this is a prime fishing hole...be nice to the locals, ask them what is biting, and you can trade sinks with their casts); 3) fishing jet boats can rip by (rarely); and 4) this is a popular sandy beach sunbathing spot, and you might need your mirrored goggles on bright sunny days when there is more than just the sun in your eyes. Enjoy! Update May 2016: Big Rock is back and better than it every was in the past. There is much more support on the seam and big 20-30 second downtime is now possible. The old charc next to the rock still works, but you can now sink right into the seam about ten feet down from the rock. If you get a huge ride (25+) and travel, there is a piece of small rebar sticking up from the bottom of the river, but reports are that it is not that bad.

Notes	I\ve been surprised how good this spot is this year at these low flows. Entry is good from each side, with the beach side appearing to be the better choice. Mysteries of 25 seconds totally possible and you can totally get deep. I hit it with guppy Gavin today, who got his first mystery move today (he got two)!! It was 107 degrees out and the water was perfect. You can basically up high or low. Great stuff!

Notes	Another great set with Tim, Mike, Ryan & Joel. We think it\ll probably still be good at lower water.

Notes	Mike, Ryan and I hit it today. Mike got his first dips in a while and was fully tranced. Nice to have another zombie tell Ryan and I that we aren\t crazy and it is in fact better than ever here.

Notes	did Oxbow to Dabny Park.. put in just below Oxbow where there there are several parking spots by a YMCA camp,because they wouldnt let us in the park with dogs. that cuts off 2 miles from the run not putting in at the oxbow boat ramp. Saw nice squeeze 15 minutes into the paddle on a right bend in the river... nothing epic but would be fun to dork arond there for grins... No park and play access. We did 3 miles down to Dabny in 45mins in a Canoe, the river was moving quick and we werent paddling that much. Only mentioning this spot because i may throw my squirt boat in the canoe next time... and it be a fun exploratory mission on a nice day.

Notes	Probed it out with a new member of the portland crew, Jono (paddling a Drain)... i can tell hes a anphibian at heart and will be at home in the Realm. welcome to the neighborhood Jono! Once we get him in a sinker boat, im sure hell be hooked on mysteries after one good Ranch session. it seemed to be the same old Big Rock, with only getting my head under for 2 out of 20 rides. Makes you work for it... like always, this is not really a quality mystery move spot.. but more of like a spot that you can do mysteries at. Still fun to get out and get wet.

Notes	Ran from dabney park to lewis & clark park (where the spot is) on the Sandy River. Nothing worth doing upstream of the normal spot, however, the regular spot was pretty sweet at 3250ish! I made 15-20 attempts and got great downtime. The rock is actually under water, and i was surfing across the wave it created and initiating off the corner just like we would at lower water. I got at least two 7-10 rides and enough success to make it worth more probing at these water levels.

Notes	slightly too high, but still fun. slightly pushy in eddy right behind rock;had 1 out of 10 good rides... once down, i could maintain altitude a couple feet under.. entrance was a quick stroke perpindicular to the eddy line, then turning to a 45 of the line with another couple strokes. hold the gentle charc, and wait for drop before beginning spin to left. This seemed to be the part of the charc that i always forget and then re-figure out after a while...
