|Western Pearlshell mussels in Satsop River|
Last summer’s mussel surveys in the Satsop River drainage led to the observation of two additional Western Pearlshell (Margaritifera falcata) mussel beds in the Satsop River watershed--one located in the headwaters of the East Fork Satsop River and another near the confluence of the Satsop and Chehalis River. One of the most immediate and striking things you notice when visiting these populations is the differences between in the size of mussels and how dissimilar their habitats are.

We will keep you posted as the field season progresses. Right now, we are setting up our monitoring sites and beginning to look for signs of female mussels getting ready to release their larvae.
You can help us study freshwater mussels, too. If you see any mussels, leave them in the water where you found them and send me an email (Teal_Waterstrat@fws.gov) with the location, a description of the mussels, and a picture if possible.
