Officials with Texas Parks and Wildlife are concerned after the invasive zebra mussels were found in Lake Ray Roberts in Denton County.
The lake is used as a water source for the Dallas area. But it’s too early to tell how the mussels will affect the water supply flowing into Dallas.
This is the second lake in Texas to see zebra mussels. The first was a tributary on Lake Lavon.
TPWD believe the source of the mussels is Lake Texoma. Zebra mussels were found there in 2009.
The problem with the mussels is that they clog public water in-take pipes, harm boats and motors and they cover boat docks, and are a safety hazard because of their sharp edges.
Authorities believe they came from a boat that was in the waters of Lake Texoma at some point.
The boat operator did not clean the boat before putting it in Lake Ray Roberts. Officials say the infestation is recent.
The mussels were found in several locations under the dam.
Lake officials are urging boat operators to make sure their boats are cleaned before using them in the lake. That means draining all the water out of the boat and letting it dry.
It also includes cleaning and drying the boat trailer or any vehicles before they come in contact with the water.
If there are containers on the boat that have water from Lake Texoma, it should be emptied.
Lake officials have a video on how to clean your boat. You can find it here.
