4.1.5 Soils <br /> Soil Pit 11 was dug on a higher area, likely an old point bar within the slough, and contained <br /> hydric soil with a redox dark surface (Indicator F6) and oxidized rhizospheres on living roots. <br /> 4.2 Wetland B <br /> 4.2.1 Location <br /> Wetland B is a small seasonal aquatic site that measures 437 square feet (0.01 acre) (Photo 8). <br /> 4.2.2 Classification <br /> Under the Cowardin Classification System for Wetlands and Deepwater Habitats (Cowardin et <br /> al., 1979), Wetland B is in the Palustrine System, Emergent Persistent Class. <br /> 4.2.3 Vegetation <br /> Wetland B is a seasonal aquatic site with a sparse cover of threesquare bulrush at the <br /> perimeter. The overstory is a mature cottonwood gallery forest. <br /> 4.2.4 Hydrology <br /> Wetland B is a depression that is seasonally saturated to inundated by the shallow <br /> groundwater table. <br /> 4.2.5 Soils <br /> The presence of hydric soils was assumed in this seasonal aquatic site. <br /> 4.3 Wetland C <br /> 4.3.1 Location <br /> Wetland C is located in a shallow swale on the south side of the Big Thompson River. Wetland <br /> C measures approximately 733 square feet (0.02 acre) (Photo 9). <br /> 4.3.2 Classification <br /> Under the Cowardin Classification System for Wetlands and Deepwater Habitats (Cowardin et <br /> al., 1979), Wetland C is in the Palustrine System, Emergent Persistent Wetland Class. <br /> 4.3.3 Vegetation <br /> Wetland C is dominated by saltmeadow rush growing with quackgrass. <br /> 4.3.4 Hydrology <br /> This depression is part of an old secondary channel of the Big Thompson River and it interacts <br /> with the seasonally high groundwater of the alluvial aquifer. <br /> 4.3.5 Soils <br /> Soil Pit 7 was dug within Wetland C and contained hydric soil with a redox dark surface (176) <br /> and oxidized rhizospheres on living roots (Photo 9). <br /> 4.4 Wetland D <br /> 4.4.1 Location <br /> Wetland D is located southeast of Wetland C in a swale that is an abandoned river channel. <br /> Wetland D measures approximately 404 square feet (0,01 acre) (Photo 10). <br /> 3 <br />
