94 cents to $25.17 an acre, with a u^ial cost of $10 to $12. Costs where 

 cotton is grown, as given in Chapter VIII, are of the same general 

 order, being high under pumping systems in Kern County and the 

 Tulare Lake areas and low under gravity systems. 



Miscellaneous Crops. 



The term "miscellaneous crops" usually includes such annuals as 

 corn, sorghum, grain, and beans, and, where not grown as specialty 

 crops, would also include vegetables and other truck crops. Ordinarily 

 their water requirements — one or two irrigations per season — are about 

 the same and, when not grown as specialty crops, none of them stands 

 apart from the others as to permissible irrigation charges. A moderate 

 charge for irrigation water for such crops is always assumed. No 

 special inquiry was made in connection with the present study regarding 

 costs of producing these crops, the thought being that present charges 

 for irrigation furnish an adequate guide for them. 



Table 36 presents present irrigation water costs under a number 

 of typical San Joaquin Valley irrigation sj'stems which include in their 

 irrigated crops substantial percentages of general crops.

IRRIGATION SYSTEMS SERVING SUBSTANTIAL PERCENTAGES 



OF MISCELLANEOUS CROPS 



> Sec Bulletin 21, DiN-ision of Engineering and Irrigation, State Department of Public Works. In some cases 

 there is an additional cost for operating private pumping plants and for maintenance of sccondiry laterals. 



> From Chapter VIII, Tables 42, 48 and 53. In some rases there is an additional cost for operating private pump- 

 ing plants. 



Costs given in the above table are, with three exceptions, seen to be 

 much higher .in the irrigation districts than under the mutual and 

 public utility companies represented bj' the last six listed. The sys- 

 tems \vlii<'h have all-season or nearly nil-season water are perhaps best 

 typified by .such enterprises as the .Modesto and Turlock irrigation 

 districts, both of these having storage and a full gravity supply and 

 both having aceonii)l.ished the development of most of their irrigable 

 acreages. It is tlie conclusion of this report that $5 an acre is a 

 reasonablt! charge for inisccl!;nii'(ins crops in the upper San .To.Trpiiji 

 Vallev counties.
