CANON CITY — For two weeks, many in our community have noticed something off: tap water with a swamp-like smell and earthy taste. Public concern rose sharply after a special meeting where residents described homes reeking of odor even after showers. Businesses say it’s hurting their image in this tourism-reliant city.
What officials are saying
The City’s Water Department confirms the issue began in late July, tied to drought-driven low river flows in the Arkansas River. Those conditions allowed naturally occurring algae to grow more easily than usual. Both the city and the Colorado Department of Public Health and Environment say the smell comes from compounds like geosmin and 2-methyl-isoborneol (MIB). At the levels found, there’s no known health risk.
Why drought matters
When the river’s flow slows down, algae have more opportunity to multiply. Normally, sufficient water movement keeps algae and their byproducts in check. But with drought, water isn’t refreshed as often, letting compounds that cause smell build up.
What residents are dealing with
People say the odor is noticeable throughout their homes, and many feel they can taste it when cooking or brushing teeth. Businesses tell city leaders that what visitors experience contributes to a disappointing impression of Cañon City. These issues come as tourism has already been under strain.
Steps being taken
The city has released water quality reports, including analysis of recent geosmin and MIB levels. Water Department Superintendent Travis Payne has shared updates and reassurances. The city is also convening a Water Shortage Watch Committee to review supply, conservation tactics, treatment controls and regulatory compliance.
What you can do
- Run cold tap water until it clears before using it for drinking or cooking.
- Use cold water for boiling and brushing—it often reduces odor.
- If possible, use filtered or bottled water for sensitive uses until normal conditions return.
- Support local water conservation efforts—lower usage helps maintain flow and reduces the conditions allowing algae growth.
Cañon City’s water isn’t dangerous, according to the latest findings. But the smell and taste are real, and reflect broader challenges dealing with drought and water system management. City leaders say solving the odor issue could take weeks to months, depending on river conditions and treatment adjustments.
