USGS scientist pauses during field work in a stream impacted by acidic runoff and metal contamination. Iron precipitates are visible on the stream's rocks. The mesh pyramid is an insect emergence trap.

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.

The mesh pyramid is an insect emergence trap. A riparian zone rich in terrestrial insects can provide an alternate food source for fish in metal-impacted watersheds.
