Marin Municipal Water District

The watershed lands we own and protect stretch over 21,635 acres, including more than 18,900 on Mt. Tamalpais and 2,700 adjacent to Nicasio and Soulajule reservoirs in west Marin. An additional 35,000 acres of privately owned watershed drains into those two reservoirs. In addition to being a valuable source of water for our customers, the Mt. Tamalpais Watershed is a natural wildland of great biological diversity and a popular recreational destination. We have a staff of rangers, natural resource specialists and maintenance workers who take care of the watershed. Their responsibilities include protecting resources, managing fire risks, monitoring plant and animal populations, restoring natural habitats, maintaining access roads and trails, assisting visitors and providing nature education programs for school children and adults.
