What We Do

Anacostia Riverkeeper works to protect and restore the Anacostia River. We create opportunities for people to enjoy, learn about, connect with, and care for the river.

From water quality monitoring to advocacy work, we work constantly to ensure a swimmable and fishable Anacostia.

Through boots on the ground restoration work like trash cleanups, green infrastructure, and stormwater education, we hope to continue the Anacostia down the path to resurgence.

Our Boat Tour and Friday Night Fishing programs ensure that everyone has free and easy access to enjoy our shared river.
