# 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.
