The effect of the rains from the southern region of the watershed is traveling downstream. Yesterday, the South Fork and Main-stem of the Shenandoah River was still running high and muddy/discolored. The E. coli levels at all five of the sites tested on the South Fork and the five sites tested on the Main-stem, including Manassas Run, exceeded the previous instantaneous Virginia water quality standard threshold of 235 E. Coli CFUs per 100ml of sample for primary recreational contact.
