Comments | | Cross sectional area was 86% of the regional curve. If the bankfull elevation was raised to be closer to the curve, it would change the stream type to be more of an "F" channel. The benches, pools, and floodplain outlets warrant this segment to be a C to B departure and not a C to F. | Different |

AdjustmentNarrative | The channel is moderately incised with evidence that incision was recent and may be ongoing during large flow events. Incision is likely exacerbated by the forest road encroachment. A stream type departure of C to B was assessed due to incision. The channel is overwidened and filling with coarse sediment deposits along the sides. Much less mid channel accumulation than downstream. Forest road along left bank is a significant encroachment and cuts off the historic valley/floodplain. | Historic incision but berming and road fill are mostly responsible for incision and entrenchment. Looks like stream may have accessed wetland to north. Re-routing road would be good project. Significant widening and aggradation and planform along with stream power at this slope (~1.3%) could yield a volatile reach. | Different |
