Definitions: ID = The monitoring station ID and corresponding waterway. Sample Date = the date on which the fecal coliform sample was taken that corresponds to the risk rating. Fecal Coliform = the FC count measured in the sample in units of number per 100 ml. Level of Concern = Low (less than 100 FC/100ml), Medium (100-199 FC/100ml), High (200-999 FC/100ml), Extreme (>1000 FC/100ml). % of Total Watershed = the total area of the watershed that the sampling station represents.

Prior to 2016, different Low/Medium/High/Extreme categories were used, which you will notice in the popups, but not the coloring.
