Does the site have the potential to improve water quality? D 1.1. Characteristics of surface water outflows from the wetland: Wetland is a depression or flat depression (QUESTION 7 on key) with no surface water leaving it (no outlet). points = 3 Wetland has an intermittently flowing stream or ditch, OR highly constricted permanently flowing outlet. Z oints = Wetland has an unconstricted, or slightly constricted, surface outlet that is permanently flowing points = 1 Wetland is a flat depression (QUESTION 7 on key), whose outlet is a permanently flowing ditch. points = 1 D 1.2.

Characteristics and distribution of persistent plants (Emergent, Scrub -shrub, and/or Forested Cowardin classes): Wetland has persistent, ungrazed, plants > 95% of area points 5 Wetland has persistent, ungrazed, plants > A of area points - -3 Wetland has persistent, ungrazed plants > 1/10 of area points = 1 Wetland has persistent, ungrazed plants <1/10 of area points = 0 D 1.4. Characteristics of seasonal Characteristics of seasonal inundation: This is the area that is ponded for at least 2 months. See description in manual. Area seasonally ponded is > Y2 total area of wetland oints = Area seasonally ponded is > % total area of wetland points = 2 Area seasonally ponded is < Y4 total area of wetland points = 0 Total for D 1 Add the points in the boxes above Rating of Site Potential If score is:_12-16 = H �'6-11= M _0-5 = L Record the rating on the first page D 2.0.
