Extensive sections of the river in that area go completely devoid of oxygen each summer, killing all aquatic life.
In the river’s Upper Basin • which includes Rappahannock County i, cropland and pasture produce almost 80 percent of the unwanted nitrogen; riparian buffer zones (combined with fencing animals away from waterways) are the key to its control.
