2019 E. coli Data Tables

Our beach water quality monitoring program has ended for the 2019 season.

Please visit us again for the 2020 season. 

Please note that the information in the data tables is not checked for data entry errors.  The data is checked for errors prior to publishing the annual Beach Water Quality Report.  Further, water clarity and rainfall data is only entered into the data tables if time permits.

Water clarity is reported as the number of Nephelometric Turbidity Units or NTU on a scale from 1 to 1100 recorded at the time of sampling. The higher the number of NTU, the less clear the water and the more likely it is to contain elevated levels of E. coli.

A complete and accurate description of conditions at Huron County beaches is published every fall in the annual Beach Water Quality Report.
