Modifier"H" <br /> Permanently Flooded (Permanent) <br /> Water covers the land surface throughout the year in all years. Vegetation is composed of obligate <br /> hydrophytes (Cowardin et al 1979, pg 22). <br /> Modifier"J" <br /> Intermittently Flooded <br /> The substrate is usually exposed,but surface water is present for variable periods without detectable <br /> seasonal periodicity. Weeks, months, or years may intervene between periods of inundation. The <br /> dominant plant communities may change as soil moisture conditions change.According to Cowardin <br /> et al (1979, pg 22) "Some areas exhibiting this regime do not fall within our definition of wetland <br /> because they do not have hydric soils or support hydrophytes." Some of the areas in agricultural <br /> fields that have been flooded during the spring and early summer of 2003 and 2004, following <br /> periods of intense and persistent rainfall, may well fall into this category and may not in fact be <br /> subject to regulation as a wetland. <br /> Modifier"K" <br /> Artificially Flooded (Artificial) <br /> The amount and duration of flooding is controlled by means of pumps or siphons in combination <br /> with dikes or dams.Water and wastewater treatment facilities are included under this category.This <br /> definition does not appear to include stormwater ponds. <br /> Modifier"Z" <br /> Intermittently Exposed/Permanent (No comparable Cowardin category) <br /> Exhibits features of both Intermittently Exposed and Permanent water regimes(Santos and Gauster <br /> 1993, pg 31). <br /> Modifier"W" <br /> Intermittently Flooded/Temporary(No comparable Cowardin category) <br /> Exhibits features of both Intermittently Flooded and Temporary water regimes(Santos and Gauster <br /> 1993, pg 32). <br /> Modifier"Y" <br /> Saturated/Semipermanent/Seasonal (No comparable Cowardin category) <br /> Exhibits features of the Saturated,Semipermanent and Seasonal water regimes(Santos and Gauster <br /> 1993, pg 32). <br /> Modifier"U" <br /> Unknown (No comparable Cowardin category) <br /> The water regime is not known (Santos and Gauster 1993, pg 32). <br /> Discussion <br /> Type 1/1L <br /> The description provided for Type 1 wetlands and the reference to the absence of wetland vegetation <br /> Svoboda Ecological Resources 1350 Orono Oaks Drive <br /> Project No.: 2007-061-03 41 Ron Ridgeway <br />
