development, based upon projected population increases, consists
of four 10-year stages of development starting with year 11 of
project operation. Total benefits for the 50th year of operation
are projected as constant for the latter one-half of the 100-year
period of analysis,

Because of the stage development, it is necessary for benefit-
cost analysis and cost allocations to adjust costs and benefits to
take into account the rates of occurrence, This adjustment is
accomplished in Part X of this planning report.

Table 10 summarizes and shows the derivation of capital costs,
annual expenses, and annual recreation benefits that are used in
subsequent financial and economic analyses. It should be noted
that the capital costs and annual expenses do not include a share
of joint costs or expenses which are allocated in Part X of this
report .
