Wild guess on flow range
Bridge Creek is the end of this section of river--a somewhat arbitrary determination--but it almost certainly isn't a take-out in the sense that any boater who has hiked in to Wooley Creek would voluntarily choose to end their run here and hike back out. The reason the section break is at Bridge Creek it because 1) some boaters enter Wooley Creek via paddling Bridge Creek and 2) some boaters hike up the Wooley Creek Trail to put-in at Bridge Creek. Boaters who have been paddling Wooley Creek upstream of Bridge Creek will almost certainly want to continue on Wooley Creek, which does not increase in its difficulty level until downstream of Wooley Camp, another couple of miles downstream. For packrafters seeking to hike in, paddle Wooley Creek and hike back out without boating the more challenging lower gorges, the logical point to take-out of the creek and begin the return hike is at Wooley Camp.
