DIRECT ECONOMIC IMPACTS

The direct economic impacts due to listing and critical habitat designation occur over several
economic sectors and are unique to particular stretches of the rivers. A complete description
of these impacts is detailed in Chapters 11-9 and 11-10 of Volume II of the Economic
Analysis. The direct economic impacts were found to stem from both flow. alterations and
nonflow activity changes.

Table 8 presents the direct economic impacts for each State over the time for proposed
critical habitat designation. For Arizona, Colorado, New Mexico, Nevada, Utah and
Wyoming, the impacts are predominantly negative, For California, the impacts are all
positive. For the Colorado River Basin as a whole, the overall impacts are positive. For the
livestock feed, recreation and electric power sectors, the impacts are negative. The other
crops, non-petroleum mining, oil and gas production, construction, and combined
manufacturing the impacts are positive. The net effects of these offsetting direct impacts is
that the total direct impacts for the Colorado River Basin are positive.
