Reserve and Road Update

Elkhorn road storm damage

This winter has provided us with a real rainy season.  We are grateful for the much-needed water, yet so much in such a short time has caused some issues.  Elkhorn Road south of the Reserve has been severally damaged and will be closed for an extended period of time.  The Reserve has suffered through power outages, downed trees, and trail damage.  Our goal is to be open and share this amazing place with you and we know you’ll be understanding of the inconvenience of road and/or trail closures.  Check here or our Facebook page for status updates.

See our map for alternate routes and road closures around the Slough.

Reserve's NOAA Funding in Jeopardy!

The proposed budget from the White House outlines severe cuts to NOAA's funding.  NOAA is the primary funder for the National Estuarine Research Reserve (NERR) and losing this funding will have a drastic impact on the work happening at the Elkhorn Slough. 

You can help us protect this funding for scientific research, wetland restoration, and so much more, with some simple action today:

  • contact your federal and state representatives and ask them to support NOAA/NERR
  • urge your friends and family to get involved and take action too,
  • share your stories on why you love Elkhorn Slough Reserve
  • visit and share the NERRA web site that provides more information and ideas on how to protect your Reserve.

Newly Published Research

new research

Did you know that the Reserve's researchers continue to have their work published in scientific journals? 

Estuaries and Coasts just published a study conducted by the Reserve's Research team lead by Rikke Jeppesen, Ph. D, which investigated how the lack of dissolved oxygen in the water affects fish and oysters in the slough.  Water control structures such as tide gates play a major role in managing water flow at the slough, but it does have impacts on water quality and life in the slough.

You can read the published study here.



Elkhorn Slough harbors the largest tract of tidal sart marsh in California outside of San Francisco Bay.
