LENTIC PROPER FUNCTIONING CONDITION (PFC) STANDARD CHECKLIST

HYDROLOGIC
1. Riparian-wetland area is saturated at or near the surface or inundated in "relatively frequent" events (1-3 years)
2. Fluctuation of water levels is not excessive
3. Riparian-wetland zone is enlarging or has achieved potential extent
4. Upland watershed not contributing to riparian-wetland degradation
5. Water quality is sufficient to support riparian-wetland plants
6. Natural surface or subsurface flow patterns are not altered by disturbance (i.e., hoof action, dams, dikes, trails, roads, rills, gullies, drilling activities)
7. Structure accommodates safe passage of flows (e.g., no headcut affecting dam or spillway)
VEGETATIVE
8. Diverse age-class distribution (recruitment for maintenance/recovery)
9. Diverse composition of vegetation (for maintenance/recovery)
10. Species present indicate maintenance of riparian soil moisture characteristics
11. Vegetation is comprised of those plants or plant communities that have root masses capable of withstanding wind events, wave flow events, or overland flows (e.g., storm events, snowmelt)
12. Riparian plants exhibit high vigor
13. Adequate vegetative cover present to protect shorelines/soil surface and dissipate energy during high wind and wave events or overland flows
14. Frost or abnormal hydrologic heaving is not present
15. Favorable microsite conditions (i.e., woody debris, water temperature, etc.) is maintained by adjacent site characteristics
EROSION DEPOSITION
16. Accumulation of chemicals affecting plant productivity/composition is not apparent
17. Saturation of soils (i.e., ponding, flooding frequency and duration) is sufficient to compose and maintain hydric soils
18. Underlying geologic structure/soil material/permafrost is capable of restricting water percolation
19. Riparian-wetland is in balance with the water and sediment being supplied by the watershed (i.e., no excessive erosion or deposition)
20. Islands and shoreline characteristics (i.e., rocks, coarse and/or large woody debris) adequate to dissipate wind and wave event energies
