The tables below show the proposed average monthly reductions in diversions and the
reductions in on-farm deliveries for each reach. Although the reductions in diversions
were assigned to a reach based on the dist\ibution of irrigated acres, in some cases the
reductions would occur further upstream depending on the location of the main stem
headgate. The amount delivered on-farm was based on the average conveyance loss for
each reach. Data on conveyance losses was based on county-level information obtained
from USGS Water Use Data for 1995.

A representative deficit irrigation prograIp. could reduce on-farm deliveries and
consumptive use by about 16,500 ac-ft per year and 8,200 ac-ft per year, respectively.
On-farm reductions in consumptive use were based on an on-farm efficiency of 50
percent. The following table shows the average monthly reductions in consumptive use
for the 1975-94 period.
