1 ET unit is described in table 1 and mapped in
figures 7, 8, 9, 10, 11,
12, 13, 14,
and 15.
2 Number is not a total but the area-weighted average of ET rates for ET units in the
discharge area.
3 Annual ET 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.
