Results indicated that the channel contained more debris in 2000, perhaps because the 2000 map included smaller logs. Reach-mean debris density was 40.5 logs/km in 1999 and 60.5 logs/km in 2000 (formations omitted). Debris density was greatest in channel segments immediately downstream from the knickpoint. Only about 38% of the debris mapped in 1999 remained in the same location in 2000, but about 65% of this debris was oriented roughly parallel to the flow direction with the butt pointing upstream.
