SUMMARY <br />• Most of the properties that were evaluated as part of this survey are primarily upland <br />sites used for agricultural purposes. Irrigated crop production and livestock grazing <br />are the primary land uses for most of the area. <br />• Wetlands within the study area occur primarily along drainages and irrigation <br />ditches. The major drainages include the South Platte River, Big Dry Creek, a <br />tributary to Big Dry Creek and several irrigation ditches that carry flow during the <br />growing season. <br />• Wetlands were identified an all of the properties, except the MFM Farms site. Most of <br />the wetlands that were delineated occur along drainages that are outside potential <br />mining areas. <br />• Both jurisdictional and non-jurisdictional wetlands occur within the project area. <br />Jurisdictional wetlands occur along the drainages; non-jurisdictional areas occur in <br />depressions and cut-off channels that are not connected to jurisdictional wetlands or <br />waters of the United States. <br />• No threatened species were observed in any of the wetlands on any of the sites. <br />REFERENCES <br />Department of the Army. 1987.
