Winter Preparedness

The National Weather Service anticipates a strong El Niño this winter and their precipitation outlook indicates Marin is likely to receive more rain than normal. Also, tides could be significantly higher than predicted. Although two major flooding years in Marin's history occurred during years with El Niño episodes (‘97/98 & ‘82/83), it is not unusual to flood in the absence of El Niño, such as in 2005/06. A flood control zone-specific update regarding winter preparedness is provided below:

Fish Passage Program

Restoring fish passage
through County structures remains a high priority for Marin County Public Works. Since 2005, eight barrier removal projects have been completed and four more are in the design phase.

Marin Project Coordination Meetings

Marin County has monthly project coordination meetings to review and
guide projects through the environmental and regulatory permit process.

El Nino and the Tide

NOAA reports that El Nino is expected to play a significant role in yielding observed tides which are higher than predicted. Learn more.

See NOAA's Tides & Currents website for the latest information on both predicted and observed tides. Tides have recently been running up to 1 ft. above predicted and are likely to run even higher during storms.

Upcoming dates with tides predicted to be at or above 6.5 ft. include:

October 26th - 29th; November 23rd - 27th; December 21st - 26th; January 20th - 23rd; February 8th
