Denver Water Warns of Zebra Mussel Threat: A Problem We All Must Face

Zebra mussels, a small but mighty invasive species, are posing a significant threat to Colorado’s waterways. While the focus has largely been on where these mussels have been found and how to prevent their spread, Denver Water is emphasizing the broader dangers that could impact all of Colorado’s rivers, reservoirs, and more if these mussels take hold.

“Zebra mussels have an incredible ability to attach to almost anything submerged in water and can clog up systems with ease,” said Brandon Ransom, Recreation Manager for Denver Water. “Once they establish themselves, they are incredibly difficult to eradicate, which is why they’ve been on our radar for a long time.”

As Colorado Parks and Wildlife continues to monitor other water bodies for signs of infestation, it’s clear that the responsibility to prevent the spread falls on everyone. These tiny creatures can wreak havoc on aquatic environments by disrupting local ecosystems, clogging water systems, and causing widespread problems. Once they infiltrate an area, removing them is an uphill battle.

“They reproduce asexually,” Ransom explained. “Just one mussel can produce thousands of eggs, making it easy for them to spread rapidly.”

The implications for Denver Water are particularly concerning, especially when considering the network of pipes that transport water from high-country reservoirs to the Front Range. These pipes are essential for delivering water to countless taps and faucets across Colorado. Ransom stressed the importance of thoroughly cleaning any watercraft that may have come into contact with zebra mussels, especially when traveling between bodies of water.

“Lake Powell, for example, is infested,” Ransom noted. “A lot of people visit Lake Powell for the weekend and unknowingly bring back zebra mussels on their boats.”

Colorado remains one of the few states in the nation not yet fully overtaken by zebra mussels, but state leaders are determined to keep it that way.

“We need to stay vigilant, educate the public, and ensure everyone understands the potential impacts of these mussels,” Ransom urged. “It’s crucial that we do everything possible to keep them out of our waterways.”
