Freshwater mussels are facing an uncertain future in our local waterways. Once abundant in both numbers and varieties, many freshwater mussel species in the Delaware Estuary are now in danger of extinction.
Streams without mussels are at a serious disadvantage. Mussels provide valuable natural benefits, such as fortifying streambeds against erosion, and removing particles and nutrients that benefit other plants and animals. Additionally, a single mussel can filter up to 10 gallons of water per day. Imagine a healthy population of these filter-feeding powerhouses doing the work of a manmade water treatment plant!
The Partnership for the Delaware Estuary (PDE) needs your help locating streams with mussels, as well as those with no mussels at all. Working with local watershed organizations, volunteer partners play an important role in helping scientists monitor the health and locations of these extremely threatened animals, and identifying streams in need of mussel restoration.

Guidebook: Freshwater Mussels of the Delaware Estuary
Call a friend or two, and head out to the streams to look for mussels! This guidebook will cover safety, survey preparation and technique, how to spot and identify mussels and more. Use this guide to help fill out your datasheets.
Data Sheets: Download
Print these data sheets and take them along while mussel hunting. When you get home, use your filled-out data sheets to submit your findings (or lack thereof) and photos to the link below. Scientists will use your information to identify mussel populations for future restoration projects. By rebuilding mussel populations throughout the Delaware Estuary region, we aim to restore healthy streams and clean water for everyone with "all-natural," inexpensive tactics.
Submit: Your Data
Take me to the Mussel Data Portal! Note: Scientists want to know where you DID NOT FIND mussels just as much as where you did; zero is data too!
