a primary index as determined from the New Jersey Hydrologic Integrity Assessment Process (Henriksen and others, 2006; Kennen and others, 2007)
b surrogate index as determined from the New Jersey Hydrologic Integrity Assessment Process (Henriksen and others, 2006; Kennen and others, 2007)
c primary regulatory index for the New Jersey Department of Environmental Protection (J.L. Hoffman, NJDEP, written commun., 2007).

# indicates that site is an index station

* If the index is spatial, percentile values are from the distribution of values for the selected index for all sites of the same stream type if the index is spatial

** These sites are index sites, which are considered to be relatively undeveloped (least amount of urbanization, less than 15% urban landuse) for a long period of record (at least 50 years). The entire period of record for these sites are considered baseline.
