Economic and Financial Analyses

Recreation

Recreational aspects have been evaluated by the National Park
Service in collaboration with the Bureau of Outdoor Recreation. The
development of recreational lands and facilities in conjunction with
the integrated Narrows-Jackson Lake plan would provide $340,000 of
annual benefits initially. With the beginning of project operations
benefits are projected to increase at the rate of $18,200 a year,
in an ascending scale, for a 50-year period at the end of which the
additional annual benefits would total $910,000. That amount ($910,000)
is projected as a constant for the latter half of the 100-year period
of analysis. Additional recreational facilities after the tenth year
would be necessary to accommodate the increasing recreational use.
These recreation benefits are converted to annual equivalent values
for the period of analysis of 100 years and interest at the rate of
3-1/8 percent as shown in table 22.

Total benefits

In summary, the total annual benefits for the plan of develop-
ment are as follows:
