Entero Count

Enterococcus (“Entero”) is a fecal indicating bacterium that lives in the intestines of humans and other warm-blooded animals.

[i] 4 Days Total Rain (in)

4 Days Total Rain (in)

The combined rainfall for the day of sampling, prior day, two days prior and three days prior. More than 1/4 inch is considered a “wet weather sample.”

Number of Samples

Total number of samples included in these calculations.

[i] Geometric
Mean
close

Geometric Mean

A measure of central tendency (a weighted average) used by NYS DEC and the US EPA to assess water quality. The geometric mean is defined as the nth root (where n is the number of samples) of the product of the Enterococcus measurements. A geometric mean over 30 fails the EPA criteria for safe primary contact.

[i] Maximum
close

Maximum

The highest Enterococcus count we have recorded at this site (“>” indicates an unknown number greater than this number and reflects the upper limit of our scoring ability for this sample).

[i] Minimum
close

Minimum

The lowest Enterococcus count we have recorded at this site (“<” indicates an unknown number less than this number and reflects the lower limit of our scoring ability for this sample).

The Catskill Creek flows from the Franklinton Vlaie wetland in Schoharie County through Albany County and into Greene County. Forest and agricultural land cover much of the watershed. Most of the urban development in the Catskill Creek watershed is concentrated in the lower section of the watershed, which has helped preserve the upper watershed’s habitat value for fish. The creek downstream of the Route 23 Bridge is also important overwintering and spawning habitat for several fish species. The creek has several popular swimming holes and fishing spots along its course.

SAMPLING PARTNERS

Catskill Site Selection 042414 JLERiverkeeper partners with local residents and with the Catskill Creek Watershed Awareness Project at Cornell Cooperative Extension to sample in the Catskill Creek watershed. For the first two years of our study, we sampled only the lower portion of the watershed, from Cairo to the mouth in the Village of Catskill. In 2014 we worked with watershed residents to identify additional sampling sites and expand sampling coverage to the headwaters.
