District Lands and Estimated Hater Use

The Bureau of Reclamation has classified the lands to determine the number
of acres suitable for crop production of various types. This classification
has been used to estimate water demand by assigning expected crops to each
land classification and then establishing a duty for each expected type of
use. New avocado plantings have surpassed the new citrus plantings In recent
years. Avocado trees require good air and ground drainage. Consequently,
areas previously considered open land are being planted to avocado trees.
In the District's 1967 report, avocado planting was estimated to ultimately
be 2,600 acres. The revised and current estimate Is approximately 11,100
acres (which is an Increase of 8,500 acres*). Citrus planting has been re-
duced from our original report (17,600 acres to 9,100 acres). The following
tabulation summarizes the results.
