(DC) (Anacostia Watershed Society) Volunteers will help AWS to release about 400 freshwater mussels into the Anacostia River! In 2015, we started surveying the native species of freshwater mussels in the Anacostia River to understand their diversity and abundance. In 2018 we started a mussel propagation project partnering with the Harrison Lake National Fish Hatchery run by the U.S. Fish and Wildlife Service in Virginia collecting local broodstock from the Anacostia River. Volunteers are critical to keep this project going and to meet our goal of enhancing mussel populations to increase their water filtration capacity to help clean our river.
