Today’s conditions are compared to similar conditions in the past when it was or was not suitable for swimming at the sampled locations.  See precautions click here

Swimming suitability is based on E. coli concentration and temperature. 

The standard for swimming in this report is E. coli bacteria concentrations less than 235 cfu/100 ml.  This standard developed over years of study, showed that only about 30 out of 1000 swimmers would experience illness when the E. coli were less than 235 cfu/100 ml. 
Up until 2019, Virginia’s water quality standard for freshwater beach advisories or closures was a single sample maximum of 235 E.coli CFU/100 ml. Virginia no longer has a single sample  maximum or any criteria for primary contact recreation in fresh water.

This site is not a health advisory. You use the Rivers at your own risk.  While 235 cfu/100 ml is a standard used by many jurisdictions, Virginia currently has no standard for freshwater primary contact recreation (swimming).  Virginia Department of Health suggestions for swimming safety are here. and here
