Historical Consumptive Use. An assessment of historical consumptive use was performed
for 1950 through 1994 using the water budget procedure described earlier with temperature and
precipitation data for Lamar (1950-94 NOAA). The canal and lateral losses were 23 and 6
percent, respectively (1990, Boyle), and minimum deep percolation and tail water losses were
20 percent and 5 percent, respectively, of the field deliveries. As shown in Table 10, the
historical consumptive use averaged 8,698 acre-feet annually for 1950 through 1994, and
ranged from 3,338 acre-feet in 1964 to 14,110 acre-feet in 1952.

Following is a summary of the historical consumptive use per share and per irrigated

acre:

The yield for 1,625 shares would average about 1,220 acre-feet annually for 1950 through
1994.

Use as a Replacement Source. In 1997, LAWMA's Fort Bent Ditch interests produced 1,022
acre-feet of consumable replacement water.
