​Rule 14 Plan Presumptive Depletion Factors (PDF)
 

Supplemental Flood Irrigation = 0.36

Sole Source Flood Irrigation = 0.50

Sprinkler Irrigation = 0.75

Lawn Irrigation = 0.85

Drip Irrigation = 1.00

Weighted PDF = Based on acres of each type of irrigation method described above.  As an example, if a farm has 200 acres of which 100 acres is supplemental flood irrigation and 100 acres is sprinkler irrigation the weighted PDF would use the following formula:
 
     (100 ac x 0.36) + (100 ac x .075)​ = 0.555
                              200 ac

 
Note:  The Supplemental Flood Irrigation PDF can change from year to year and is set by the SEO/DEO before each Rule                 14 Plan is submitted in February.
​ 
             It should also be noted that the SEO/DEO has final determination of each well’s PDF.
