USGS scientists samples the East Fork of the Upper Arkansas River

East Fork of the Upper Arkansas River

Detailed Description

USGS Scientists study the effects of trace metal contamination on diets of stream fish. Vegetation surrounding this relatively pristine stream is dominated by deciduous willow, which are inhabited by riparian spiders that consume adult aquatic insects emerging from the stream. Regionally, streams are impacted by acid mine drainage and natural mineralization.
