Water quality testing has been carried out by the Jasper County SWCD staff since 2010 at the sites shown on the map below.  Since water testing  only gives one snapshot in time, it takes multiple years of data to draw any valid conclusion from water data.  This will continue to be an on-going effort.

To the left is a map of the water sampling points. Below are real-time graphs from the US Geological Survey's Sentry Gauge on the Iroquois River near Foresman, IN. These graphs shows nitrogen concentration and turbidity.
