Mussels Unleashed: TVA's Innovative Plan to Clean Up Rivers
16 Nov
Summary
- TVA releases 100 rare Appalachian rockshell mussels into Powell and Clinch Rivers
- Mussels act as "livers of the rivers," filtering water and removing pollutants
- Project aims to protect endangered species and maintain ecosystem balance
As of November 16th, 2025, the Tennessee Valley Authority (TVA) has unveiled an innovative plan to clean up the Powell and Clinch Rivers. The agency has released 100 carefully bred Appalachian rockshell mussels into these waterways, harnessing the natural power of these creatures to filter and purify the water.
Freshwater mussels play a crucial role in aquatic ecosystems, acting as the "livers of the rivers." These stationary mollusks feed by filtering water, removing algae, bacteria, phytoplankton, and even viruses and chemical runoff. Just one mussel can filter up to 15 gallons of water per day, making them incredibly important for maintaining the health of rivers and streams.
The Appalachian rockshell mussel, in particular, has a tiny population and is considered an endangered species. By releasing these mussels into the Powell and Clinch Rivers, the TVA aims to not only clean up the water but also protect a species on the brink of extinction. This effort will benefit the overall biodiversity and ecosystem balance of the region.
The project is a stellar example of how local conservation efforts can leverage the power of nature to address environmental challenges. Similar initiatives, such as the use of goats for invasive plant removal and dogs for endangered species detection, have also proven effective in recent years.
