When surface water is absent, the water table is often <br /> i near the surface. Santos and Gauster (1993, pg 31) add that the water table, after flooding <br /> ceases, is very variable, extending from saturated to a water table well below the surface. This <br /> ' accurately descnbes the situaiion that frequent�y occurs within reed canary grass wetlands where <br /> there is saturation to the swface or even several inches of inundation after snow �h. In most <br /> years, by the end of May, surfa�ce water is no longer evident in, many of these basins. During <br /> ' June, the water table continues to recede unt� by August, the water table may be two or more <br /> feet below the surface. Many of these areas are used for livestock pasturing and for harvest�g <br /> ir�adow hay. Wetlands with a "C" modifier that consist predorivnantly of reed canary grass <br /> � should be categorized as either Type 1 or Type 2 depending on the length of time that water is <br /> present. This modifier is the most difficult to specifically assign to a Type 1, Type 2 or Type 3 <br /> category as it could apply to any of the three. <br /> ' ModiBer"D" <br /> �easonal Well-Urained(No comoarable Cowardin catego� <br /> , Santos and Gauster (1993, pg 31) descn`be this modifier as applyuig where surfa�e water is <br /> present for extended periods especially early in the growing season. The water table, after <br /> flooding ceases falls well below the ground surFace. This modifier would appear to apply to <br /> ' floodplains and bottomland hardwood forests (Type 1 L) as descnbed above. Modifiers "C" and <br /> "D" seem to overlap to a certain extent and could also apply to reed canary grass wetl�ds as <br /> well. <br /> � ModiBer"E" <br /> Seasonal Saturated�,No co��rable Cowardin cate�ory� <br /> ' Surface water is present for extended.periods especially early in the growing season, and remains <br /> saturated near the surface for rrwst of the growing season(Santos and Gauster 1993,pg 31).
