From The Boulder Daily Camera (Katie Langford) via The Burlington Record:
The Colorado Department of Public Health and Environment designated a stretch of Boulder Creek from the mouth of Boulder Canyon through Boulder’s Eben G. Fine Park as impaired in December 2019, and that assessment has not changed…
The city is continuing its program to better understand sewer sheds and creek inflow, Owen said, though it continues to be a “very challenging problem” not only in Boulder, but across the state.
City officials cannot prevent people from entering the creek, but the city has installed signs cautioning people about entering the water, Owen said…
The state continues to monitor Boulder’s progress on reducing E. coli levels, Nason said, and will likely reevaluate water quality in 2023 and updating the creek’s impairment status in 2025.
