Texas’ Canyon Lake infested with invasive Zebra Mussels

Invasive ‘zebra mussels’ have been positively identified in Canyon Lake in part of what Texas Parks and Wildlife officials said is the state’s southernmost affected lake: the Guadalupe River Basin.

According to a release from TPWD,  Zebra Mussels originated in Eurasia and reproduce at a rapid pace. The invasive species can have serious economic, environmental and recreational impacts on reservoirs and rivers.

Zebra mussels can cover shoreline rocks and litter beaches with sharp shells, clog public-water intakes, and damage boats and motors left in infested waters. Click on the following links below to access two different stories.

“This is the first positive documentation of zebra mussels in Canyon Lake and in the Guadalupe River Basin,” said Brian Van Zee, Inland Fisheries regional director for TPWD. “Although marina staff have intercepted several incoming boats over the years that had invasive mussels attached, it is essential that boats stored on infested lakes be decontaminated before they’re moved as they are a key pathway for spreading this invasive species.”

Zebra mussels have extremely sharp shells and tend to cover shoreline rocks. They can also clog water pipes and damage boats and motors left in infested waters. Treating zebra mussel infestations can cost millions of dollars, so the TPWD is urging the public to properly clean watercrafts to prevent further infection.
