This section was first descended by kayakers in 2006 as part of an American Whitewater boating flow study in cooperation with South Feather Water and Power Ageny. The flow was 120 cfs for this study and the team felt it was a little high for this creek. The boating team had a difficult time with large drops that were not quite runnable at that flow and which were technical and time consuming to portage. Still, the team felt that the creek was very impressive and might be a very good run at just the right flow, especially as boating techniques continue to develop.
