Enterococci are bacteria that are found in the GI tract of warm-blooded animals, which includes all birds and mammals.  Their presence in surface water indicates recent contamination with fecal waste.  Counts are expressed as cfu or colony-forming units.  Counts greater than 104/100 ml are shown in red as they indicate that water is not suitable for recreational use. 

^Approximately 1.7 " of rain fell within the 48 hours prior to sampling.

^^Rain of up to 5" fell around the area within the 24 hrs prior to sampling.  Some locations did report higher rain totals.
