Boaters Beware: Invasive Mussels Established In Holt Reservoir

TUSCALOOSA, AL — State officials are asking anglers and boaters to be vigilant when out on the water as invasive zebra mussels have established themselves in the Holt Reservoir on the Black Warrior River near Tuscaloosa, which presents cause for concern amid the possibility of cross-contamination between bodies of water.

The United States Geological Survey (USGS) says zebra mussels are an invasive, fingernail-sized mollusk that is native to fresh waters in Eurasia.

"Zebra mussels negatively impact ecosystems in many ways," the USGS says. "They filter out algae that native species need for food and they attach to — and incapacitate — native mussels. Power plants must also spend millions of dollars removing zebra mussels from clogged water intakes."

What's more, zebra mussels can attach to boat motors and boat hulls, according to Stop Aquatic Hitchhikers, reducing performance and efficiency. Their sharp shells can also cover rocks, swim rafts, and ladders – presenting a safety hazard to unprotected feet.

The Alabama Department of Conservation and Natural Resources also points out that zebra mussels cause extensive damage to personal property such as boats but also to the natural habitat that supports recreation. The department says it is partnering with the U.S. Army Corps of Engineers and Alabama Power to address the problem.

The department's Wildlife and Freshwater Fisheries Division provided the following tips to combat the spread of zebra mussels to other bodies of water:

• Empty live wells and clean thoroughly.

• Empty any container with lake water and allow to dry.

• Remove aquatic plants from your boat and trailer.

• Pull your drain plug.
