E. coli exceeds standard from Pueblo to Holly

Key takeaways

  • E. coli exceeds the standard from Pueblo to Holly.
  • The development comes four weeks after the Pueblo spill.
  • The river below John Martin Dam is no longer described as clean.

What changed

Four weeks after the Pueblo spill, E. coli levels exceed the applicable standard along the river corridor from Pueblo to Holly. The condition extends downstream past John Martin Dam, where the river is no longer described as clean.

Area affected

The reported stretch begins in Pueblo and continues east to Holly. John Martin Dam is specifically identified as a dividing point: the river below the dam is included in the affected area.

The report does not describe the spill as resolved. Instead, it identifies an ongoing water-quality condition four weeks after the event, with E. coli above the standard across the named stretch.

What the report establishes

The Kiowa County Press reported the development in a report titled “Four weeks after the Pueblo spill, E. coli exceeds the standard from Pueblo to Holly, and the river below John Martin Dam is no longer clean”. The central facts are the timing—four weeks after the Pueblo spill—the geographic range from Pueblo to Holly, the E. coli exceedance, and the condition of the river below John Martin Dam.

What to watch

  • Whether the affected stretch changes in later water-quality reports.
  • Whether officials issue updates about the river below John Martin Dam.
  • Whether the E. coli condition continues beyond the four-week mark.
