Datum: o NAD27 o NAD83 o WGS84 o Other (specify):

Rationale for reach breaks:

III. Description of potential and rationale (should include description of hydrologic regime, stream type(s), and riparian plant communities at potential; may include additional information such as valley type, gradient, entrenchment ratio, sinuosity, width/depth ratio, and bed and bank materials):

PFC Assessment Form (Lotic)

Riparian area/stream name: Reach ID: Date:

Yes No NA HYDROLOGY

1) Floodplain is inundated in “relatively frequent” events.

Rationale:

2) Beaver dams are stable.

Rationale:

3) Sinuosity, gradient, and width/depth ratio are in balance with the landscape setting (i.e., landform, geology, and bioclimatic region).

Rationale:

4) Riparian area is expanding or has achieved potential extent.

Rationale:

5) Riparian impairment from the upstream or upland watershed is absent.

Rationale:

112 Appendix A—Instructions and Forms

Yes No NA VEGETATION

6) There is adequate diversity of stabilizing riparian vegetation for recovery/maintenance.

Rationale:

7) There are adequate age classes of stabilizing riparian vegetation for recovery/maintenance.

Rationale:

8) Species present indicate maintenance of riparian soil-moisture characteristics.

Rationale:

9) Stabilizing plant communities capable of withstanding moderately high streamflow events are present along the streambank.

Rationale:

10) Riparian plants exhibit high vigor.

Rationale:

11) An adequate amount of stabilizing riparian vegetation is present to protect banks and dissipate energy during moderately high flows.

113Appendix A—Instructions and Forms

12) Plant communities are an adequate source of woody material for maintenance/recovery.

Rationale:

Yes No NA GEOMORPHOLOGY

13) Floodplain and channel characteristics (i.e., rocks, woody material, vegetation, floodplain size, overflow channels) are adequate to dissipate energy.

Rationale:

14) Point bars are revegetating with stabilizing riparian plants.

Rationale:

15) Streambanks are laterally stable.

Rationale:

16) Stream system is vertically stable (not incising).

Rationale:

17) Stream is in balance with the water and sediment that is being supplied by the drainage basin (i.e., no excessive erosion or deposition).

115Appendix A—Instructions and Forms

Are there factors present preventing the achievement of PFC or affecting progress towards desired condition that are outside the control of the manager?

o Yes o No

If yes, what are those factors? Check all that apply.

o Flow regulations o Road encroachment o Mining activities o Oil field water discharge o Upstream channel conditions o Augmented flows o Channelization o Other (specify:)

Explain factors preventing achievement of PFC:
