  💧Drought conditions continue, causing decreasing water levels, as pictured. On the bright side, the measured E. coli levels at all the South Fork, North Fork and Main-stem River sites tested were well below the

Wednesday 06.10.2026: Water levels in the Shenandoah River watershed continued to recede. Despite only sporadic rainfall across the region since the testing event last week, four specific monitoring locations exhibited a notable spike in E.

This Wednesday, June 3, 2026, water levels at all but one of our monitored sites had receded back to normal levels for this time of year. Notably, E. coli levels also decreased at every location.

After five days of rainfall, E. coli bacteria levels in the North Fork, South Fork, and Main-stem of the Shenandoah River have risen significantly since our tests on May 19. Out of 14 sites monitored

Unfortunately, no, the E. coli level measured in the Shenandoah River at Lockes Landing public boat landing (site FC05) in Clarke County, VA was 248.1 MPN (most probable number) of colony-forming units per 100 mL

Great news heading into the holiday weekend, with no rain in the forecast, we’re hopeful that E. coli levels will stay consistent with yesterday’s results at the river sites we tested, which were all below

Friends: This week’s testing results show the E. coli levels at all monitored sites, except one, were below the EPA’s recommended “do not exceed” threshold of 235 CFU per 100mL of water sample. As in

The E. coli levels at all the River sites and Manassas Run (FW36, Warren County VA) tested were below the EPA’s recommended “do not exceed” threshold of 235 CFU of E. coli bacteria per 100mL

In addition to lower water levels, mostly clearer conditions, and cooler temperatures this week, we observed a significant change in the E. coli level at our Hawksbill Creek site near the Luray-Hawksbill Greenway Pocket Park.

While collecting water samples yesterday along the North Fork, South Fork, and Main-stem of the Shenandoah River, we couldn’t help but notice how many people were out enjoying the River! From fishing and kayaking to

At only one River site this week, the northernmost testing site on the Main-stem Shenandoah River, FC08 Castleman’s Ferry public boat launch in Clarke County VA, the E. coli level of 365.4 CFU/100mL exceeded the
