parcel include two wet meadow areas and the vegetation community along the waters <br />edge of the ditch. Based on the field investigations, the wetlands were concluded to be <br />man-induced as a consequence of irrigation tailwater flow from adjacent upgradient <br />agricultural fields. Irrigation tailwater was observed to flow onto the parcels from the <br />irrigated secondary terrace to the east at two locations, the first location being ditch <br />outflow between the Arends and Reinoehl parcels, the second location being field <br />overflow from the center of the Arends parcel. The irrigation tailwater flows onto the <br />parcels and spreads out onto the primary terrace within confines of microtopographic <br />elevations, forming ephemeral wet areas. Water that reaches the tailwater ditch <br />eventually ends in lakes or dries prior to reaching the South Platte River. For these <br />reasons, the wetlands identified at the site were determined to be artifacts of the land use <br />and were concluded to be non-jurisdictional based on definitions within the U. S. Army <br />Corps of Engineers (USACE) 1987 Wetland Delineation Manual ("If hydrophytic <br />vegetation is being maintained only because of man-induced wetland hydrology that <br />would no longer exist if the activity (e.g. irrigation) were to be terminated, the area <br />should not be considered a wetland") and Federal Register 33 CFR parts 320 through <br />330 (November 13, 1986), Part 328 ("Artificially irrigated areas which would revert to <br />upland if the irrigation ceased" are generally not considered to be "Waters of the United <br />States") (Figure 5.
