Data Sampling & Compilation
Data were collected at the Poughkeepsie Water Treatment Facility, and three USGS survey sites (below Poughkeepsie , South Dock at West Point , and south of Hastings on Hudson ). The data were then averaged to create annual means. The deviation shows the years with above-average temperatures (values>0.0) and below-average temperatures (values<0.0) for the Hudson River.
