What is the current status of zebra mussel population in the us?

As of October 2023, zebra mussels continue to pose a significant ecological and economic threat in the United States. They have spread widely across the Great Lakes and into several inland waterways, rapidly reproducing and outcompeting native species. Efforts to manage their population, including prevention and control measures, are ongoing, but their presence remains a major concern for water resources and infrastructure. Some regions have reported localized declines due to environmental factors, but overall, zebra mussel populations are still robust.
