on-farm irrigation systems and power costs for pumping at the water
supply source. Thus, these parcels have the potential for the
benefits of irrigation to exceed the costs of converting them to
irrigated agricultural use. The two parcels together total 288 acres
in size.
The two potentially irrigable parcels in the San Juan Watershed
are listed in Table 5-1, along with a description of their
characteristics. The first four columns of Table 5-1 give the parcel
number, net irrigable acres, land class and climatic zone descriptions
for each parcel. The fifth column of Table 5-1, entitled "Cropping
,
Pattern Suitability", provides an indication of whether the cropping
pattern that maximizes repayment capacity is suitable for the land
class of the individual parcel under consideration. Column six of
Table 5-1 provides a description of the percentage amount of tree
canopy on each parcel, and column seven provides a description of the
parcel's distance from the theoretical central location of a farm
equipment warehouse. The remaining columns in Table 5-1 describe any
adjustments that were made to residual repayment capacity to reflect
each parcel 's characteristics~
As Table 5-1 shows, Parcels S90 and S91 constitute approximately
288 acres of potentially irrigable lands in climatic zones E and D in
the San Juan Watershed. These parcels are in close proximity to each
other, and could be farmed as a single unit. Both parcels have land
classes suitable for the alfalfa, malt barley crop rotation used in
the Level A economic analysis.
