D.4.3 Cropping Pattern

For the preliminary analysis of PIA, a cropping pattern with the

highest net agricultural returns for climatic Zone F was used.

Table D.2 identifies this cropping pattern as well as the net

agricultural return.

D.4.4 Preliminary PIA Analysis

A preliminary PIA analysis was performed comparing a parcel's

payment capacity with a preliminary estimate of the cost to pump

wa ter from the river to the parcel. Th i s prel iminary wa ter cost was

based on the static pumping lift (the difference in elevation from

the water surface in the river to the elevation of the parcel) for

gravity irrigated fields plus a field delivery pressure of 60 psi for

sprinkler irrigation. The La Plata River, which would supply water

to the parcels in the Ute Mountain Ute La Plata Watershed, is located

to the west in the Ute Mountain Ute Reservation. The water surface

elevation was taken at points where the river comes closest to the Ute

Mountain Ute reservation. Detailed tabulations of the analysis are

shown in Appendix D.I.

No parcels in the Ute Mountain Ute La Plata Watershed had a positive

residual payment capacity. Table D.3 summarizes the results of the

analysis.
