Water resource issues ranging from water supply reliability and water quality to storm water management and ecosystem enhancement have been at the forefront for agencies, organizations, residents and agricultural producers in the Tomales Bay region for over three decades. The Tomales Bay region’s water resources provide water supplies and support extraordinary and diverse ecosystems.
In June 2007, the Tomales Bay Integrated Coastal Watershed Management Plan (ICWMP) was completed. The ICWMP is a cooperative effort by the Tomales Bay Watershed Council (which includes federal, state and local agencies, and local stakeholders), Bolinas Community Public Utilities District, Inverness Public Utility District, Marin Municipal Water District, and North Marin Water District to identify management strategies and regional projects that meet multiple objectives for the Tomales Bay region.
On an individual basis, each of these entities has investigated and evaluated various water resource and management issues and options for the overall health and well being of the watershed, and the water and environmental resources within their jurisdictions. The history of collaboration within the region demonstrates the collective and individual capacity of local, state and federal agencies and private organizations to address regional water resource and watershed issues. It also provides the foundation that will support future actions to protect and enhance water supplies water quality, critical coastal areas, and important ecosystems of the Tomales Bay watershed region.
The planning area includes the Marin County critical coastal areas (CCAs), which include Tomales Bay, Lagunitas Creek, Walker Creek, and four ASBS (Areas of Special Biological Significance) areas.
