Enterococcus is an EPA-approved fecal contamination indicator.

Samples taken by citizen scientists trained by Riverkeeper, and processed on the Riverkeeper vessel, according to the 2014 Quality Assurance Project Plan.

Rainfall data comes from wunderground.com. Wet weather is a common trigger of fecal contamination.

About this location:

This fishing area is located 3/4 mile upstream of the Dashville Dam, at the Route 32 bridge. Downstream of this point, the Wallkill passes through forested land cover until joining Rondout Creek. The river here is very slow moving and calm.
