The maximum used to be listed as 1200, but that was for a different gauge estimate. This is still class III at 2000 cfs.
Take out at the bridge where the East Side Chewuch Road crosses the river. Parking is available on river left approximately 100 yards from the bridge at the Y in the road. The best access is at the beach on the downstream right side of the bridge but it is private property. Downstream river left is a feasbile access that is also private property but you may be able to find away to stay off private property. The upstream river right side of the bridge is Washington State land and would be worth exploring for improved access on public land.
