Federal bill targets golden mussel invasion in California waterways

What does this do?

HR 3717 establishes a federal program to combat the golden mussel, an invasive species spreading in California waterways, with primary focus on the Sacramento-San Joaquin Delta and any other U.S. waters where the mussel is found or may appear. A federal task force would research the mussel's biology, track its spread, and develop control or elimination methods. Within one year of passage, the task force must publish guidelines for stopping the mussel's spread, including establishing boat inspection stations.

Who does it affect?

The bill directly affects people who live or work near California's waterways, including farmers, water utilities, commercial and recreational boaters, fishermen, and local governments. Organizations such as states, universities, ports, and nonprofits could apply for competitive grants to develop removal technologies.

Why does it matter?

The golden mussel can attach and grow on water pipes, boat hulls, fish screens, and canals, threatening water infrastructure and aquatic environments. Without coordinated research and control measures, the mussel's spread across U.S. waterways could continue unchecked.

What does it cost, and who pays?

• Up to $15M authorized per year
• Covers 2026 through 2030
• Annual approval by Congress required
