in the watershed-scale delineation method comes in several forms: 1) whether the
potential regulated sites for planning purpose have been located, 2) whether the outline
and attributes of the site are described correctly, and 3) whether the rating represents a
reliable level of accuracy in predicting the likelihood that a site is regulated.
