The Greater Caddo Lake Association
Aug 19 2007
We have received tremendous support and encouragement from Texas Parks & Wildlife officials and US Fish & Wildlife and other agencies. They are doing what they can to help with the resources they have. What we need is for them, and our community groups, to get more and better resources.
It is time for everyone to call on all elected officials from Louisiana and Texas and urge that the states and the federal government wake up to the magnitude of this problem at Caddo and other lakes and provide an appropriate level of emergency response. State Senator Kevin Eltife, and State Representatives Bryan Hughes and Stephen Frost are already helping. Congressman Louis Gohmert is very committed to helping. Senator Kay Bailey Hutchison has also helped.
But we are going to need a lot more help, and fast. And that means we need you to let them know you appreciate their efforts. And we need you to contact other elected officials in Texas and Louisiana and urge them to get on the ball.
Currently, our situation is comparable to a rural volunteer fire department combating a raging forest fire that is spread across 32,000 acres in two states.
New infestations are spreading all over the lake daily. Many shoreline property owners in the Jeems Bayou area in Louisiana can no longer get their boats out of their stalls or fish off their docks. Almost the entire eastern side of Big Green Brake is so thickly matted with giant salvinia that even Go-Devils can no longer move through it. Large rafts of giant salvinia are threatening the city of Vivian, Louisiana's water supply intakes.
In Big Green Brake alone, an estimated one-half square mile of spawning grounds has been lost to the world's worst invasive aquatic plant. Nothing lives under giant salvinia. The plants block out all sunlight and deplete all dissolved oxygen from the water. (See photo: Big Green Brake 8/02/07.)
In Texas, the fight against giant salvinia has largely been in the capable hands of the Cypress Valley Navigation District and the Texas GCLA. This is that rural volunteer fire department, scrounging equipment and supplies to hold the line. They are doing what they can but they can't beat back this monster plant by themselves no more than three guys with a garden hose can beat back a 32,000 acre forest fire.
Two new dimensions to the fight against giant salvinia at Caddo Lake must happen immediately. One of these new dimensions can be accomplished locally. The other will require the commitment of significant federal or other multi-state resources.
One: boat road openings in the Caddo Lake Giant Salvinia Containment Barricade must be tightened. The protected western area of the lake must be better protected.
Two: massive containment and control operations must begin soon on the Louisiana side of the lake, where infestations are rampant. The contaminated area must be cleaned up
CLOSING BOAT ROAD OPENINGS:
CVND/GCLA Weed Wardens are removing giant salvinia and water hyacinth from the barricade and chasing down and spraying new infestations daily. But as the huge infestations in Big Green Brake and Tar Island continue to expand, doubling in volume every 5 to 7 days, tens of thousands of plants migrate westward every time the winds blow from Louisiana to Texas. Too many of these plants are finding their way through these wide openings.
Also, bass fishermen chasing trophies, duck hunters working on blinds, and sightseers are moving in and out of these infested waters and helping to disperse giant salvinia into the boat roads. Every time a boat blows through one of the openings at high speeds the job of tracking down migrating giant salvinia on the western, protected side of the lake gets tougher
CVND is now considering a proposal to erect new containment structures at these openings that will require boaters to reduce their speed to near-idle and to go through a zig-zag pattern before re-entering an open boat road. Ample warning buoys and signs will require boat operators to reduce speed and boaters will be asked to check their boats to make sure plants are not clinging to the boat or engine before entering the protected area. Transporting giant salvinia in any fashion without a permit is illegal and punishable by a $500 fine. (see photo giant salvinia on boat & trailer).
Boaters must become aware that when they go west through boat roads C and A, they are leaving a contaminated zone and entering a protected one - and they must behave accordingly.
Unfortunately, there were no state or federal resources available to take those steps - and efforts to generate a community-based response did not gain traction
When January 2007 flooding washed hundreds of acres of giant salvinia out of Jeem's Bayou and into Big Green Brake and Tar Island, a community-based response took shape around CVND and GCLA on the Texas side. Harrison County Judge Richard Anderson convened an urgent meeting that created a guiding council to raise funds and provide management oversight. $65,000 was raised from Harrison County, the City of Marshall, Northeast Texas Municipal Water District, CLI, CVND, AEP/SWEPCO and Lone Star Steel. These funds, along with over 1,000 contributed volunteer hours of labor, provided the resources to build the two-mile long containment barricade and support the Weed Warden Spray & Removal initial operations.
Judge Anderson, CVND Chairman Ken Shaw, GCLA President Robert Speight and others, including Caddo Lake&'s best friend in Austin, governmental liaison specialist V.A. Stephens, lobbied the legislature for funds to continue the Caddo Lake giant salvinia control program in Texas waters. With the unwavering commitment and hard work of State Senator Eltife and State Representatives Hughes and Frost, $120,000 per year was earmarked for Caddo Lake boat roads with the understanding that CVND's primary needs are maintaining the barricade and suppressing infestations west of the barricade.
This model community effort, partially supported by CLI and U S Fish & Wildlife Foundation, has made it possible for us to still save the western half of Caddo Lake from being overwhelmed by giant salvinia. But it can only hold the line for so long, and of course it does not attack the source of the problem, the huge and rapidly expanding infestations in Louisiana.
Most estimates of the cost of arresting the giant salvinia at Caddo Lake are in the $1.5 million a year range. To stop the expansion and beat back infestations will require federally funded projects and the cooperation of Texas and Louisiana agencies.
U.S. Representative Louis Gohmert (1st District, Texas) has been among the first in Congress to recognize the magnitude of this threat to Caddo and other lakes and the need for federal funding. He is working with federal agencies to find immediate help. He is working with our local groups to develop ideas for future appropriations. (Congressman Gohmert will make a fact-finding tour of Caddo Lake August 29 and tour CVND/GCLA operations.)
U. S. Senator Kay Bailey Hutchison has also
assisted this effort by helping to obtain $40 thousand dollars of U.S.
Fish & Wildlife funds to support Spray and Removal operations.
