|The following is
a list of the different National Recreation Areas and their state. The list
is current as of December 2005.
National Recreation Area: Twelve NRAs in the system are centered on
large reservoirs and emphasize water-based recreation. Five other NRAs are
located near major population centers. Such urban parks combine scarce open
spaces with the preservation of significant historic resources and
important natural areas in location that can provide outdoor recreation for
large numbers of people.
