Natural Resources

Sunset on the reservoir

Marin Water's Mt. Tam watershed is also an important community resource, with its network of trails and reservoirs. The Mt. Tam watershed is home to more than 1,000 species of plants and 400 species of wildlife, and includes rare, threatened, and endangered species. We are committed to sustaining the ecological health and biological diversity of the watershed, with programs to monitor wildlife such as the northern spotted owl, osprey, the yellow-legged frog and the western pond turtle. Our team is also monitoring rare plants, and mapping and managing non-invasive plant species.

Lagunitas Creek, which begins above the district’s reservoirs near the peak of Mt. Tam, is a spawning and rearing ground for endangered coho salmon and steelhead trout. We also collaborate with other downstream land management agencies to restore habitats and monitor fisheries, to help preserve what is now the largest remaining population of Central California Coast coho.

Our California roots run deep. We are committed to responsible, sustainable land management that preserves and protects our watershed for generations to come.
