The float from Rockport to Concrete is 11.3 miles in the stream catalog, but it feels like 10. There are no significant navigation hazards besides the usual deceptively swift current and a tree here and there, with plenty of room to dodge them. Take out at the mouth of the Baker River, upstream side. It's an unimproved lauch and retrieval site. Although it's a sand, silt, gravel site, it's suitable for drift boats and sleds, not to mention rafts, canoes, and 'toons.

Have a good drift and enjoy the fishing.

Sincerely,

Salmo g.
