1 ET units are described in table 1 and shown
in figures 7, 8, 9, 10, 11,
12, 13, 14,
and 15.
2 This number is not a total ET rate but the area-weighted average of the adjusted ET
rates for the ET units in the discharge area.
3 Ground-water discharge is rounded to two significant digits. Total is computed as the
sum of the rounded values listed for each ET unit and may not be consistent with that computed as the product of the
area-weighted average and the total acreage.
