Putting in at Bay Creek vice Buck Hollow will be a lot better of a scenerio due to river levels. Akers states their data on the Alley gauge, which is a good river level, the 47 cfs is based on a Buck Hollow gauge. Two Rivers was probably basing their judgement off of this gauge, which as Al states, it'll be work. Bay creek is way down river from Buck Hollow, but above Alley, therefore, by doing the math, the river levels from Bay Creek to Alley should accomodate your float during this time period specified. I doubt a drag here and there will be any big deal.
