Humboldt Baykeeper's Community Outreach engages people of all ages in understanding, enjoying, and preserving the health of Humboldt Bay. Our Bay Explorations program highlights the area's natural history. Our dedicated volunteers lead tours, monitor local streams, table at community events, clean up trash from local beaches and the Samoa Bridges, and watchdog everything that impacts the bay, from illegal dumping to development proposals.

Come celebrate the Marbled Godwit athe the 17th annual Godwit Days Festival. Observe many bird species and wildlife through our selection of field trips, lectures, workshops, and boat excursions led by experienced local guides. Tour the expansive mudflats, the wild river valleys and the rocky ocean coast of this sector of the Klamath bioregion in northwest California.


Humboldt Baykeeper will provide early morning tours aboard our Boston Whaler, featuring the abundant and diverse bird life on Humboldt Bay.

Humboldt Baykeeper maintains an Adopt-a-Highway stretch on the Samoa Bridges spanning Indian Island the North Humboldt Bay. At least six times a year, volunteers head out on Saturday mornings to intercept the great trash migration from our roadsides into the estuary and the ocean.

We recently began tallying the number of plastic bags collected along this 2-mile stretch: bags that would have otherwise blown into Humboldt Bay.

Ocean Night is a monthly, all-ages event hosted by Surfrider Humboldt, Northcoast Environmental Center, and Humboldt Baykeeper. Each month, we feature an environmental film focused on coastal and water issues as well as a surf flick. Check our website or sign up for e-Currents for announcements. Doors open at 6:30 p.m. and the movie begins at 7 p.m. at the Arcata Theatre Lounge. Hope to see you there! 



In 2009, Humboldt Baykeeper initiated an internship program in conjunction with Dr. Alison Purcell O’Dowd, Assistant Professor and Environmental Science Program Coordinator at Humboldt State University. Interns are students enrolled in Applied Ecological Restoration (ENVS 450) who study riparian and instream conditions in Widow White Creek, a tributary of the Lower Mad River in McKinleyville.

Baykeeper provides sampling equipment and guidance, along with experts at Pacific Watershed AssociatesRedwood Community Action Agency, and Humboldt Fish Action Council


Why Widow White Creek?

Widow White Creek has been impacted by urbanization of 25% of the watershed, as well as logging and low-density residential development in the upper watershed. It historically supported coho salmonsteelhead troutcutthroat trout, three-spine stickleback, and sculpins, and thus is an important target for restoration. Citizen "First Flush" monitoring over several years has found extremely high levels of fecal coliform in the creek, particularly at monitoring sites near residential and commercial areas. The sources of the coliform bacteria are unknown.

Most of the Widow White Creek watershed lies within the unincorporated community of McKinleyville. The watershed has lost 33% of its timber and meadow areas compared to historic conditions.

By 2001, one-quarter of the watershed was classified as “dense urban” by Klein and Anderson. In their analysis on the effects of urbanization on flood frequency estimates for lower Widow White Creek, they found that the 2-year flood flow has increased 229% over pre-development conditions.



California Coastal Clean-Up Day A Success!

Sept. 19th- California's beaches and inner waterways may be collecting spots for marine debris, but Californians have demonstrated their support for clean beaches by turning out by the tens of thousands at the 25th Annual Coastal Cleanup Day. At this time the California Coastal Commission has 65% of the clean-up sites reporting.  

With 65% of the cleanup sites reporting, the statewide count stands at 66,550 volunteers which should approach the event goal of 70,000. Those volunteers picked up 819,394 pounds of trash and an additional 88,899 pounds of recyclable materials, for a total of 909,294 pounds. When all reports are in totals are expected to exceed 1,000,000 pounds.
