Water supply for these lands historically has been variable depending upon water ri ghts and the canal system whi ch serves them. Wi th the water supply anticipated from construction and operation of the proposed project, these lands should have the highest irrigation efficiensr and crop yields of any lands within the project. This evaluation area comprises a total of 7,020 acres of project lands. Of this amount 5,430 acres are presently irrigated and 1,590 acres are non- irrigated. The nonirrigated land can be further subdivided as follows: Nonirrigated land occurring in b10cks--9JO acres; nonirrigated land inter- spersed in small scattered tracts--660 acres. Evaluation area A is composed of subareas A1, A2, and AJ which now have water supply differences as follows: Wi thout Project Condi tions - Evaluation area A1 comprises presently irrigated lands with a moderate water supply shortage. Evaluation area A2 covers presently irrigated land with a severe water shortage. Some small scattered tracts of nonirrigated land which will receive project water are also included in evaluation areas A1 and A2' These tracts will be used with presently irrigated lands in existing farm units. Evaluation area AJ comprises large blocks of nonirrigated land which will receive project water and will be used for new farm units with project development. Wi th Project Condi tions - Evaluation areas A1, A2, and AJ will have the same water supply and productive capaci ty, and are combined as evaluation area A in the analys i s. Evaluation Area B Evaluation area B lands are also on Florida Mesa and have soil character- istics similar to those of evaluation area A but slopes are steeper and range from J to 6 percent. These lands are generally located along the major drainageways in the central and southern portion of Florida Mesa but are also interspersed wi th lands of evaluation areas A and C. They are usually disected by small drainageways, and as a result have short slopes and short lengths of irrigation runs. Soils have been grouped into land capabili ty class III because they have severe limitations requiring special management practices for long-continued cu1 tivation. Water supplies and farm irrigation efficiencies have been and will be about the same as for evaluation area A. Adapted crops will be the same but yields will be generally lower than for evaluation area A. This evaluation area comprises a total of 9,820 acres of project lands. Of this amount, 6,255 acres are presently irrigated and 3,565 acres are non- irrigated. Large blocks comprise 2,080 acres of the nonirrigated land and the remaining 1,485 acres are interspersed in small tracts. _ 6 _
