o 00 M CHAPTER II EVALUATION OF DIRECT AGRICUL 11.JRAI.. BENEFITS FROM '!HE SILT PROJECT The evaluation of direct agricultural benefits for the project is based on the proposed facilities and the project lands to which the Bureau of Reclamation plans to furnish irrigation water. Intervening lands not included in the project are not considered in the report. The assumptions made concerning the level of management and application of practices as a result of project development are not technical recommendations of the Department of Agriculture for the best land and water use on the project. It is assumed that the level of management and application of practices represents the average that will exist during the project evaluation period. Evaluation Areas - General Description To facilitate the presentation of basic agricultural data and to assist in the analysis of direct agricultural benefits, project lands were grouped into evaluation areas. Soils, cl imate, and water supply within each evalu- ation area reflect similar crop adaptations, productivity, land and irriga- tion development and production costs. Eight evaluation areas were established to represent conditions in the project area. These areas have been designated by the letters A, B, C, D, E, F, G and H. The acreage of each is shown in table L Table 1. - Irrigable land acreage by evaluation areas, Silt project Project Lands : Harvey Mesa A : B . .
