Texas Lake Invaded: Tiny Mussel Spreads West
25 Jul
Summary
- Lake Meredith in Texas confirmed infested with zebra mussels in June 2026.
- The mussels are reproducing, posing a threat to western waters.
- Boaters must clean, drain, and dry equipment to prevent further spread.
Invasive zebra mussels, first noted in North America in the late 1980s, have now established a reproducing population in Lake Meredith, Texas, as confirmed in June 2026. This marks Texas's 35th fully infested lake and raises concerns about the species' potential westward expansion.
Officials reported finding both larval and adult zebra mussels, indicating active breeding within the lake. This discovery designates Lake Meredith as a critical "stepping stone" for further spread, originating from Eurasia and rapidly colonizing North American waters.
The primary method of spread for these mussels is through contaminated boats, trailers, and equipment. This has allowed them to move efficiently between waterways. Prevention is key, with authorities emphasizing the importance of cleaning, draining, and drying all watercraft and gear before transporting them to new locations.
Established zebra mussel populations can cause significant ecological and infrastructural damage. They attach to hard surfaces, impacting water supply systems, recreational facilities, and native species. The ongoing spread serves as a stark reminder of how easily invasive species can alter landscapes, emphasizing the connection between global shipping, recreation, and water management.
