Summary
  1. Go to Gallery for views of stream conditions when sampling was conducted, along with some streambed conditions.

  2. Of the 5 non-metals parameters for Outstanding Waters evaluation, only the E. coli standard has been exceeded.

  3. This occurred at Stoner on 7/19/21 and 7/16/2020 and at Coal on 9/21/2020, the standard being 126/100 ml.

  4. While not an Outstanding Waters parameter, total coliform also was measured for indication of water quality.

  5. The standard of 200/100 ml for CO Recreation Class I water has been exceeded at 10 of the 12 streams sampled.

  6. Total coliform presence likely results from fecal material carried by runoff into the streams, that is, from grazing.
