Table C-1. (Continued) Descriptions of wetlands on the Chikuma Property. Refer to Table C-2 for lists of species observed in these wetland areas. Wetland Location Photo Number s) Descriptions and Comments Jurisdictional Status This wetland area occurs in the low areas that extend onto the Chikuma property from the Myrna property (located on the north side of the Chikuma property). This area occurs near Wetland the confluence of Big Dry Creek and the associated with tributary/ditch. Major species in this wetland Jurisdictional - low areas along C-7 include prairie cordgrass, chairmaker's rush Connected to other Big Dry Creek and alkali muhly (Muhlenbergia nsperifolia). In jurisdictional (W-CS) general this area tends to be somewhat drier wetlands than W-C7. Recent flood debris suggested that following periods of heavy rainfall in late July, the water was 2-3 feet deep in this area. Hydrophyflc species accounted for 64 percettt of the observed s ecies. Small wetland in natural No specific observations were made in this Non-jurisdictional depression No Photo wetland. Overall, the species composition is Isolated -not along Big Dry similar to wetland W-C8. connected with Big Creek D Creek ry -C9 In general, these wetland areas are similar to the wetlands along the tributary to Big Dry Creek; however because the drainage basin of Big Dry Creek is larger, these wetlands are more likely to be subject to flooding. On two separate occasions in 2004, flood waters (2-3 Wetlands along feet deep) covered most of the wetland areas Jurisdictional - Big Dry Creek C-8 and along Big Dry Creek. Wetlands occur in Connected to other (W-C10) C-9 saturated areas along the stream channel. jurisdictional Major species include reed canary grass and wetlands woolly sedge (Cnrex lanuginosa). Coyote willows occur in small patches in various places in this wetland. Flows in 2004 were high enough to wash out the bridge in the lower part of the area along Big Dry Creek. Hydrophytic species accounted for 94 percent of the observed s ecies. This wetland occurs as a narrow band along Non-jurisdictional- Wetlands along the channel of the irrigation ditch located in the Ditch excavated in irrigation ditch west part of the property. The wetland extends upland area. on west side of C-10 only 3-4 feet from the channel because of the Hydrology property steep sides of the ditch. Major is reed canary dependent on water (W-Cll) grass. Hydrophytlc species accounted for 77 diverted from South ercent of the observed s ecies. Platte River _2g_
