The remalnlng project lands were placed <br />in Class I, 2, and 3 categories depending on overall evaluations of <br />physical and economic factors. The map on the following page shows <br />the classification of lands as developed in the 1946-1948 survey. <br />On the map, the Class 5 lands are included in the areas shown to be <br />Class 6 lands. <br /> <br />The following tabulation shows the project acreage by land class <br />as taken from the 1946-1948 survey as well as the acreage taken from <br />the project water assessment records for the year 1971. The acreage <br />figures are rounded to the nearest 10 acres. <br /> <br /> 1946-48 data 1971 records <br />Class 1 5,880 5,880 <br />Class 2 33,480 34,160 <br />Class 3 23,570 26,450 <br /> Total Class 1 to 3 62,930 66,490 <br />Class 5 4,870 3,990 <br /> Total Class 1 to 5 67,800 70,480 <br />Class 6 irrigated 11,710 13,320 <br /> Total Class 1 to 5 plus <br /> Class 6 irrigated 79,510 83,800 <br /> <br />The acreage adjustments indicated by the tabulation were made by <br />reclassifying Class 5 or 6 land to a higher class and providing irriga- <br />tion service for acreages under originally nonparticipating ownerships <br />that have later subscribed for project water. Although water is not <br />presently delivered for or charges assessed against most lands cur- <br />rently included in the Class 5 category, it is believed that these <br />lands are now cultivated and irrigated with water delivered for use <br />on other lands in existing farm units. As shown by the preceding <br />tabulation, 13,320 acres of Class 6 lands are now receiving project <br />water on an annual rental basis as permitted within existing contrac- <br />tual limitation. Although the Class 6 lands were considered in the <br />land classification survey to be uneconomical for irrigated crop <br />production, some of the lands have been improved by leveling or <br />other means so that they might now meet standards for lands of higher <br />classification. In other instances, the owners of the Class 6 lands <br />may have concluded that they can accept lesser economic returns from <br />the lands than considered necessary for successful operation in estab- <br />lishing the land classification standards. <br /> <br />Virtually all of the Class 1, 2, and 3 lands within the service <br />areas of existing project canals and laterals are being irrigated at <br />present. A few small mesas containing arable lands could be provided <br />irrigation service by moderate pump lifts or by extension of existing <br />canals and laterals. <br /> <br />24 <br />
