Zebra Mussels Report from Channel 8 WFAA

In a case of what I’ll call “friendly fire” Channel 8 WFAA, Dallas, a Belo Corporation, did an story about the history of water from Texoma being transferred into Lake Lavon. “Friendly fire interviews” (my phrase), as opposed to an “ambush” interview, start as a friendly interview, then turns to take aim at the person they were at first friendly toward.

The friendly fire victim, TPWD biologist Bruce Hysmith, was interviewed and put on the defensive when Channel 8’s David Schechecter pressed Hysmith on why he didn’t get past the receptionist at the Texas Water Board with a warning about finding zebra mussels in Texoma, and used e mail to notify the North Texas Municipal Water District.

As I recall, the issue really was / is water. The NTMWD wants to keep it flowing, and they would never take it onto themselves to stop pumping. The only they would have stopped pumping is if TPWD told the NTMWD to do so. I believe TPWD, if I recall, didn’t think they had the authority to stop the water transfers, and left it up to NTMWD. Get the picture? Hot potato. Channel 8 portrays the delay in stopping water flow as being like unleashing the hounds of hell, which is probably hardly the case when one zebra mussel is found on one boat dock cable.

This story ran on Channel 8 around Thanksgiving, and the most ominous thing about it is the comment from the biologist at UT Arlington zebra mussel expert, Robert McMahon, saying, “you don’t want to know what’s going to happen …” Ouch, this is going to leave a mark.

The questions I have are –
1) do zebra mussels transport via water transfer?
2) has anyone simply looked at the water below the Denison Dam? Are zebra mussels there?

Here is where you can find the Channel 8 story on zebra mussels from November 29,2011. I have interviewed Hysmith once or twice for Lone Star Outdoor News in the past, and he’s been nothing but helpful in my gathering of information.

I am left wondering just how the zebra mussel infestation on Texoma is going to turn out. Should we be doing all the fishing possible before Texoma becomes an inert wasteland for its fishery? I will go ahead and contact zebra mussel expert Robert McMahon at University of Texas Arlington to see if he can finish the nightmare for us.

    I thank Dr. McMahon for his response as follows:

    I has proven difficult to predict what the specific ultimate ecological consequences of a zebra mussel invasion during the early stages of invasion of a water body such as is presently occurring in Lake Texoma. This is especially true for a warm southwestern lake like Texoma where the biology and impacts of zebra mussel infestation have not been previously studied. The eventual outcome of zebra mussel invasion of Texoma will partly depend on the lake’s temperature regime, productivity, and the degree to which water quality is impacted, especially water clarification, among others.

    For some general information to share with your readers you may want to read the US Geological Survey document (http://www.glsc.usgs.gov/_files/factsheets/2000-6%20Zebra%20Mussels.pdf) which gives a relatively brief overview of the general economic and ecological impacts associated with zebra mussel invasion of water bodies in North America.

    From what I’ve heard, zebra mussels are more of a bigger problem for municipality functions than fisheries. They’re lower trophic level filter feeders, just like any mussel. The problems arise with how tightly packed they can grow. I look forward to what you find out from the expert. We took a brief look at zebra mussels in one of my classes this semester.
