' water surface will be 92. 3 acres of lake less 10 . 6 acres of
' islands, or 81. 7 acres of water. Evaporation from these
lakes will be a consumptive use of water.
The consumptive use of water involves two factors : (1) tran-
spiration, which is water entering plant roots and used to build
' plant tissue or being passed through the leaves of the plants
into the atmosphere, and (2) evaporation, which is water evapor-
ating from adjacent soil , water surfaces or from the surfaces
of leaves of the plants. Water deposited on the land and
' subsequently evaporating without entering the plant system
is part of the consumptive use. Consumptive use is influenced
by temperature, irrigation practices, length of growing season
' of vegetation, precipitation and other factors. The volume
of water transpired by plants depends in part on the water at
' their disposal as well as temperature and humidity, wind move-
ment, intensity and duration of sunlight, stage of develop-
ment of the plant, type of foliage, and nature of the leaves.
The consumptive use by native vegetation is fairly constant
year to year where the water supply is adequate, but surface
' evaporation increases in wet years because of the expansion
of exposed water surfaces and moist soil areas. Where the
' water table is near the ground, surface evaporation from the
soil is almost equal to evaporation from a free water surface.
' Measurements of consumptive use indicate that water loving
' natural vegetation uses from 50-100% more water than most crop
plants. The consumptive use of water by phreatophytes, or
