They vary considerably depending on their mix of parent <br /> <br />materials. <br /> <br />The topography has a rolling appearance consisting of small ridges, <br /> <br />elevated fans and terraces changing from a few feet to over 200 feet from the <br /> <br />valley bottoms. <br /> <br />The land classification data of this report was based on the land class <br /> <br />survey of 1963 accomplished by the Bureau of Reclamation. The original <br /> <br />survey was adjusted to meet sprinkler specifications. Project lands included <br /> <br />in the plan total 8,000 acres of which 6,550 acres are new lands which are <br /> <br />not presently irrigated and 1,450 acres which have a present supply but need <br /> <br />additienal water.
