In a recent government meeting, experts discussed urgent measures to combat the invasive Asian carp threatening the upper Tennessee River Basin. Dr. Peter Sorensen from the University of Minnesota presented findings indicating that strategically placed deterrents at dams could significantly halt the carp's upstream movement. He recommended the immediate installation of a bioacoustic fish fence at Watts Bar Dam, which would serve as the first line of defense against the invasive species.

The proposed deterrents utilize a combination of sounds, lights, and air bubbles to create a barrier that prevents carp from passing through locks, a primary route for their migration. Sorensen emphasized the need for additional controls to prevent both accidental and intentional releases of carp into the water, such as through fishing practices.

The estimated cost for each deterrent installation ranges from $8.5 million to $10 million, with a projected timeline of three to five years for completion. Funding for pilot installations has been authorized under the Water Resources and Development Act of 2020, which allocated $25 million, contingent on 25% of the funds being sourced from non-federal entities.

Sorensen highlighted the economic implications of inaction, warning that failure to address the carp invasion could result in a staggering $1 billion annual economic impact. He urged decision-makers to consider temporary modifications to lock operations to reduce carp movement while the deterrents are being installed.

The meeting underscored the urgency of the situation, with experts calling for immediate action to protect the region's lakes and maintain biodiversity. The proposed measures aim not only to safeguard the ecosystem but also to ensure recreational opportunities for residents. As the threat of the carp invasion looms, the consensus is clear: timely intervention is crucial to prevent a potential ecological disaster for future generations.
