Greater Farallones National Marine Sanctuary (the Sanctuary) protects the waters off the coast of Marin, Sonoma and southern Mendocino Counties including Tomales Bay, which was designated in 2002 as a wetland international importance under the Ramsar Convention and is included in the Golden Gate Biosphere, part of the UNESCO World Network of Biosphere Reserves. Tomales Bay supports a diversity of habitats, including seagrass beds—primarily eelgrass (Zostera marina), intertidal sand and mud flats, and salt and freshwater marshes. The bay is especially important to approximately 20,000 wintering shorebird, seabirds, and waterbirds. The waters of Tomales Bay are also important to many fish species; including salmon, eel, sturgeon, halibut, endangered Coho Salmon, and the commercially important Pacific Herring that rely on its creeks and extensive eelgrass beds to spawn. The bay also supports a resident harbor seal breeding population. The Sanctuary has several programs and projects that protect and manage Tomales Bay:  The Vessel Management Plan, The Mooring Program and actions to protect seagrass.

Tomales Bay Vessel Management Plan

The Tomales Bay Vessel Management Plan (the Plan), addresses vessel sewage discharge, impacts from moorings to habitat including seagrass, derelict or deserted vessels, introduction of invasive species, disturbance of wildlife, and discharges of oil, fuel, and vessel maintenance products. The Environmental Assessment and Initial Study (EA/IS), which is included as an appendix to the Plan, analyzes the potential environmental effects associated with implementation of the Plan consistent with the requirements of the National Environmental Policy Act and California Environmental Quality Act.

Tomales Bay Mooring Program:

Moored boats have been a familiar part of the Tomales Bay landscape for many years, and moorings have historically been and continue to be concentrated in several areas on the east and west shores of the bay.

The Sanctuary and California State Lands Commission (CSLC) initiated the Tomales Bay Mooring Program on Aug 10, 2015, requiring all private vessel mooring owners to obtain a mooring lease from CSLC. The Mooring Program specifies mooring tackle to minimize marine debris, requires inspection and maintenance of moorings to prevent boats from breaking free, sinking and polluting Tomales Bay waters, damaging the seafloor and/or damaging property.  The Mooring Program also keeps moorings out of locations where there can be damage to eelgrass, threats to navigation or threats to wildlife and people swimming in Tomales Bay.

The Tomales Bay Mooring Program is based on a precautionary approach and is consistent with the mandates of the agencies that have jurisdiction over the bay. The Mooring Program ensures that boating activities are conducted in a responsible manner—through adoption and implementation of mooring policies and criteria, we can allow for this long-standing tradition of boating to continue, while not adversely affecting the bay.

The primary goals for establishing a program for siting and permitting moorings on the bay are to: protect habitat; decrease threats to and disturbance of wildlife; and ensure safe and enjoyable water-related recreation by allowing moorings in appropriate locations with appropriate materials and removing and preventing moorings and mooring materials that can harm the marine environment.

Public Process

Throughout the process to develop the Draft Tomales Bay Vessel Management Plan, GFNMS and CSLC were committed to engaging boaters and the local community in providing input for the development of the plan. To that end, Greater Farallones Sanctuary Advisory Council initiated a Working Group for Tomales Bay Vessel Management. The Working Group consisted of representatives of boating associations, shellfish growers, commercial fishermen, boat services operations, conservation organizations, shore-side property owners, and state and federal agencies with jurisdiction in Tomales Bay.

GFNMS and CSLC would like to thank the following Working Group participants for their contributions to the development of the Plan:

  • Dominique Richard, Chair, GFNMS Advisory Council
  • Colin Smith, National Park Service
  • Nanci Smith, State Lands Commission
  • Tom Moore, Dept. of Fish and Game
  • Jerry Abbot, Inverness Yacht Club
  • Mark Bartolini, Tomales Bay Boaters Association
  • George Clyde, East Shore Planning Group
  • John Finger, Hog Island Oyster Company
  • Fred Smith, Environmental Action Committee of West Marin
  • Gordon Bennett, Sierra Club
  • Willy Vogler, Lawson's Landing
  • Gene Maffucci, Herring Fishman
  • Skip Vilicich, Marshall Boat Works
  • Jeremy Fisher-Smith, Fisher-Smith Boat Works

Tomales Bay Interactive Map

A layered PDF was developed by GFNMS staff as a complement to the Draft Plan to provide a geographic context and visual representation of the proposed Tomales Bay Mooring Program criteria and other boating-related resources on the bay. This user-friendly interactive map enables the viewer to overlay several different map layers and to determine the geographic coordinates of specific locations without the use of specialized software. A revised version of the interactive map is being developed and will be available soon.

 

Previous Documents & Presentations

Vessel Usage Scoping Document

In 2007, GFNMS and CSLC produced the document, "Protecting Tomales Bay by Managing Vessel Usage: A Document for Public Input." The document was a result of a multi-agency effort to coordinate current and future vessel-related activities to improve water quality, protect wildlife and habitat, and protect public health and ensure recreational opportunities in Tomales Bay. The document presented activities currently being implemented by the participating agencies as well as proposed concepts for vessel management. The purpose of this document was to solicit vessel management recommendations from individuals and organizations in the local community and users of Tomales Bay to protect the ecosystem and public health in the bay. The document was released for a 60-day comment period and two "brainstorming" workshops were held.
