Visiting Watershed Lands

"The Mt. Tamalpais Watershed… is held in trust as a natural wildland of great biological diversity, as scenic open space and as an area for passive outdoor recreation for Marin and much of the Bay Area. Passive outdoor recreation is defined as those activities that are based on nature and that require little or no development or facilities.” -Marin Municipal Water District's Mt. Tamalpais Watershed Management Policy.

Watershed Availability

Due to public health officials’ concerns regarding the spread of coronavirus, Marin Municipal Water District offices, including the Sky Oaks Watershed Headquarters, will be closed to the public effective March 18 until further notice.

The watershed remains open to the public, with some restrictions, for recreational use daily from sunrise to sunset. The recent county health order prohibits vehicles and parking at the watershed, with the exception of people with disabilities who have the required disability placards or license plates for their vehicles. Parking for those with disabilities is available at our Sky Oaks parking lot. While the watershed remains open, visitors must comply with social distancing requirements of at least 6 feet. All volunteer programs that take place on the watershed have been canceled until further notice.

During extreme fire weather conditions, such as Red Flag Warnings, and other emergencies, vehicle access is prohibited into Bon Tempe and Lagunitas Lakes, at Sky Oaks Watershed Headquarters, and to Natalie Coffin Greene Park, Phoenix Lake. For the most current information regarding land closures during fire season please call the Marin County Fire Department’s Public Information Line at 415-499-7191 or MMWD's Sky Oaks Watershed Headquarters at 415-945-1195.
