Freshwater Mussel Reintroduction

Freshwater Mussel Reintroduction

This project supports the reintroduction of native mussels to the Mission Reach, where populations have been nearly eradicated but persist in remnant channels. Initiated in 2017, the Mission Reach Mussel Survivability Study, along with insights from the Mussel Propagation and Production Project, confirmed reintroduction feasibility. Over five years, the U.S. Fish & Wildlife Service will produce four mussel species, which River Authority staff will place in the Mission Reach. The timeline aligns with the maturation period of the slowest-developing species.

Mussels recovered during a relocation event. Species include Yellow sandshell, Pistolgrip, Pimpleback, Threeridge, and Washboard.
