The American River Conservancy is a non-profit organization of community volunteers and professionals dedicated to the protection of native fisheries, vanishing plant and animal communities, scenic vistas, cultural heritage and recreational lands within the American and Cosumnes River watersheds which lie in the foothills of the eastern Sacramento Valley in El Dorado County.

Based in Coloma, California, in the Marshall Gold Discovery State Historic Park, the American River Conservancy has a wonderful natural history exhibit and conducts environmental education programs on-site including organized hikes and walks, clean up days, home school Thursdays, Kid's Discovery Days, a lecture series and variety of workshops.

The rivers of the Sierra Nevada region provide almost 65% of the state of California's developed water needs as they travel along the way to the Pacific Ocean. Unfortunately, our waterways have historically been a dumping ground for waste. Together, we can help raise awareness about issues of watershed conservation, fighting litter, encouraging reduction of consumption and recycling, and promoting community pride. Through education and recreation, the American River Conservancy promotes a broad ethic of stewardship, ensuring healthy ecosystems now and for the future.
