Marin Municipal Water District

The MMWD volunteer program strives to connect people to nature and their water source by offering hands-on activities on the Mt. Tamalpais Watershed.

Volunteers are currently engaged in habitat restoration, trails maintenance, environmental education, biological monitoring and geographic information systems mapping.

Through their experiences volunteers gain skills, become stewards, contribute to the health and safety of the watershed and have fun while doing so.

MMWD manages 18,500 acres of land in the Mt. Tamalpais Watershed and 2,750 acres adjacent to the Nicasio and Soulajule reservoirs in west Marin. The Mt. Tamalpais Watershed has been identified by the United Nations Educational, Scientific, and Cultural Organization (UNESCO) as a key component of a biosphere reserve, a designation given to biodiversity hot spots like the Amazon rainforest.
