At low levels, there is a surf wave under Powhite Bridge. The wave is found around 3.5-4.0 feeton river left directly under the bridge. Another good beginner surf spot, but it is very shallow so tuck tight.
As with many man-made structures, the bridge creates hazards that come into play at higher water levels. Most notably the log strainers that are piled on the upstream side of the pylons. Also, the pylons create strong, uniform eddy fences and whirlpools at high levels. Avoid them both.
