Friends of the Shenandoah River continues our Summer E. coli Testing Program at public access locations on the main stem, South Fork, and North Fork of the Shenandoah River. Real-time monitoring results are made available on all digital devices to help you make an informed decision about getting on or in the water.
FOSR utilizes WaterWatch*, a comprehensive digital platform that supports data collection, management, and visualization. FOSR provides unrestricted access to our water-quality data. We ask that acknowledgment and credit be given when using and referring to these data.
