Senate Democrats Press for Swift Action on Great Lakes Carp Barrier Project
Concerns are mounting over the potential invasion of carp into the Great Lakes, a scenario that could have dire economic and environmental consequences. Senate Democrats are calling on the Trump administration to expedite efforts to prevent these invasive fish from establishing a presence in the region.
Recently, the U.S. Army Corps of Engineers halted progress on the $1.15 billion Brandon Road Interbasin Project, designed to prevent carp from accessing the Great Lakes. This pause, the second of its kind, has prompted criticism from Democratic lawmakers, including Wisconsin U.S. Sen. Tammy Baldwin. In a letter dated Sept. 22, Baldwin and others expressed frustration over the unexplained delays.
The urgency of the situation escalated when sampling crews identified numerous young silver carp just 80 miles from Lake Michigan in August. This discovery marks the furthest north these juvenile fish have been found since monitoring commenced in 2010.
Sen. Baldwin emphasized the importance of the Great Lakes to Wisconsin’s economy and quality of life, stating, “The threat of invasive carp is becoming increasingly urgent as they move closer to Lake Michigan. Without action, we will be dealing with irreversible damage to our waters, native fish, and local economies.”
Despite President Donald Trump’s directive for rapid action on the project, the Army Corps has yet to comment on the delays. Joel Brammeier, president and CEO of the Alliance for the Great Lakes, expressed concern over the project’s progress, aligning with lawmakers’ calls for transparency.
Brammeier noted that while adult carp have been found closer to Lake Michigan before, the presence of spawning activity suggests the invasion is nearing the Great Lakes. “That’s why we were so concerned,” he added.
Invasive carp pose a significant threat to the $5 billion fishing industry and the $16 billion recreational boating sector. The fish are known to deplete food sources for native species and can even injure people by leaping from the water.
The Brandon Road Lock and Dam project includes several deterrents, such as noisemakers, a bubble curtain, an electric barrier, and a flushing lock, to prevent carp from entering the Chicago Area Waterway System connected to Lake Michigan.
Funding for the project includes $274 million from Congress, with an additional $28 million allocated this year. Illinois and Michigan are contributing $50 million and $64 million respectively.
Sara Walling, water and agriculture program director for Clean Wisconsin, stressed the project’s importance, stating, “These projects that really are extremely important for a number of reasons — not just environmentally, but economically — really need to be prioritized and given the resources that are needed to get them completed.”
The Great Lakes have previously encountered challenges from invasive species such as zebra and quagga mussels, which cost an estimated $500 million annually to manage. Lawmakers are seeking a meeting to discuss the latest work stoppage and are urging for greater transparency from the administration regarding project developments.
