Dye Trace Studies in Area of Ozark National Scenic Riverways

Image showing Water Study and impacted areas
 Map of the Current River watershed (light blue), showing localities where environmentally benign fluorescent dye has been put into sinking streams or sinkholes (yellow triangles). The dye traveled underground and emerged at springs (blue circles), particularly Mammoth Spring, Greer Spring, and Big Spring. The directions of underground flow often have no relationship to the surface stream and drainage patterns. The Viburnum Trend mining district (orange and dark orange) and areas of recent mining exploration (red) are shown. Knobs of Precambrian rocks (purple) interrupt the Trend in the Current River drainage basin.
