Tributary is: ❑ Natural
❑ Artificial (man - made). Explain:
❑ Manipulated (man - altered). Explain:
Tributary properties with respect to top of bank (estimate):
Average width: feet
Average depth: feet
Average side slopes: PICt.
Primary tributary substrate composition (check all that apply):
❑ Silts ❑ Sands ❑ Concrete
❑ Cobbles ❑ Gravel ❑ Muck
❑ Bedrock ❑ Vegetation. Type /% cover:
❑ Other. Explain:
Tributary condition /stability [e.g., highly eroding, sloughing banks]. Explain:
Presence of run/riffle /pool complexes. Explain:
Tributary geometry: Pitk V #
Tributary gradient (approximate average slope): %
(c) Flow:
Tributary provides for: it
Estimate average number of flow events in review area/year: (I'1'tClk List
Describe flow regime:
Other information on duration and volume:
Surface flow is: PIWLI#. Characteristics:
Subsurface flow: tk k lit. Explain findings:
❑ Dye (or other) test performed:
Tributary has (check all that apply):
❑ Bed and banks
❑ OHWM6 (check all indicators that apply):
❑ clear, natural line impressed on the bank
❑ changes in the character of soil
❑ shelving
❑ vegetation matted down, bent, or absent
❑ leaf litter disturbed or washed away
❑ sediment deposition
❑ water staining
❑ other (list):
❑ Discontinuous OHWM.7 Explain:
❑ the presence of litter and debris
❑ destruction of terrestrial vegetation
❑ the presence of wrack line
❑ sediment sorting
❑ scour
❑ multiple observed or predicted flow events
❑ abrupt change in plant community
If factors other than the OHWM were used to determine lateral extent of CWA jurisdiction (check all that apply):
❑ High Tide Line indicated by: ❑ Mean High Water Mark indicated by:
❑ oil or scum line along shore objects ❑ survey to available datum;
❑ fine shell or debris deposits (foreshore) ❑ physical markings;
❑ physical markings /characteristics ❑ vegetation lines/changes in vegetation types.
❑ tidal gauges
❑ other (list):
(iii) Chemical Characteristics:
Characterize tributary (e.g., water color is clear, discolored, oily film, water quality; general watershed characteristics, etc.).
Explain:
Identify specific pollutants, if known:
(iv) Biological Characteristics. Channel supports (check all that apply):
❑ Riparian corridor. Characteristics (type, average width):
❑ Wetland fringe. Characteristics:
❑ Habitat for:
❑ Federally Listed species. Explain findings:
'A natural or man -made discontinuity in the OHWM does not necessarily sever jurisdiction (e g , where the stream temporarily flows underground, or where
the OHWM has been removed by development or agricultural practices) Where there is a break in the OHWM that is unrelated to the waterbody's flow
regime (e.g, flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break
