Result groupings Di:itricts ReJ!.ioflS State 14 to around $112 per acre. The total increascd earnings from irrigati'lIl is about $693 million. When this is combined with the monies from dryland farming the total 1974 agricultural earnings come to about $3.1 billion. The estimated water required for the irrigation of crops was some 4.6 million acre-feet which would have an average application rate of 1.6 acre-feet per acre. Each acre-foot of water generated about $150 of agricultural production. The results are presented in three types of areal covcrage with two formats of data presentation. In all instances, the years covered are 1972 through 1977. A warning is in order here concerning the first twO years. It was not possible to get all the data in the appropriate format for analysis. The particular problem which occurred involved the corn and sorghum crops. There exist instances where irrigated and dry land crops were not separately identified for 1972 and 1973. These years were not deleted from the analysis becausc some of the values have merit. You will note in the 1972 and 1973 material, a blank has replaced the numbers which would be affected by the nondiffcrentiated crop data. The areal coverages arc set in the following fashion. Groundwatcr Man. agemcnt Districts One through Five arc analyzed by district. Counties which have any part residing within a district are included in the district. It was assumed that virtually all of the irrigation within these counties would take place within those districts. The statements of irrigation earnings should be quite accurate. The statements of dry land earnings, on thc other hand, will be overstated if the whole county is not within the district. If increased accuracy of t\ross income figures by district is te'Juired the adjustment is easi. Iy made by subtracting thc product of average dry land earnings with thc number of acres outside the district from the gross income figure allocated to the dry land component. There arc two counties which arc handled in a special fashion. The first is Wallace County which is wholly assigned to District No.1. The other is Reno County which is distributed seventyfive percent to District Five and twcnty- five percent to District Two. The economic regions of the state are the other areal delineation. In this instance, wc are always dealing with whole county information and there is no requirement for a subcount)' adjustment. There is, however, one adjust- ment which is made. It is the shifting of counties Chase, Lyon, Marion. and Morris from Region Three to Region Four. This is a format that is used in order to place those four counties in the same region as the other COUll ties of that river basin. Finally, the analysis is operatcd with the state as one region. The purposc is to accumulate total results on a statewide basis. As mentioned above.
