Updated at 8:02 a.m. Wednesday to correct the workshop location. The workshop will be held at 4 p.m. Wednesday at the Elk Valley Rancheria Sam Lopez Community Center, 2332 Howland Hill Road in Crescent City.

State water quality scientists are seeking public comment on proposed regulations aimed at controlling waste discharge from the Easter lily bulb industry into the lower Smith River basin.

North Coast Regional Water Quality Control Board representatives will hold a public workshop Wednesday focusing on Draft General Waste Discharge Requirements for Commercial Lily Bulb operations in the Smith River Plain.

Also known as the Lily Bulb Order, draft discharge requirements seek to “protect and restore beneficial uses, such as cold freshwater habitat in the Smith River Plain,” according to the state agency’s Feb. 5 news release.

Restoring Elk Creek Would Enhance Crescent City’s Ability to Withstand Flood, Tsunami, Smith River Alliance’s Grant Werschkull Says

Smith River Alliance Co-Director Grant Werschkull acknowledged that breathing new life into Elk Creek’s wetlands could be an economic boon for Crescent City.

But to illustrate his point that restoring the tidal channels and swales would make a difference during a tsunami or a flood, he pointed councilors to a 2015 New Yorker article about the Cascadia Subduction Zone, the massive earthquakes it is capable of generating and its threat to coastal communities like Crescent City.

“The title is the ‘Really Big One’,” Werschkull said, referring to the article. “Seismologists, the experts that we have, participated in that (article) and it talks about how we are right now at a date when it is timely that it could happen.”

Domoic Acid Delays Recreational Crab Season in Northern California

From the California Department of Fish and Wildlife:

The recreational Dungeness crab season will open beginning Nov. 1, 2025, except in northern California where it has been delayed due to a public health hazard.

State health agencies determined that Dungeness crab in northern California have unhealthy levels of domoic acid and recommended delaying the opening of the recreational fishery in state waters from the California/Oregon border (42° 0.00’ N latitude) south to the Sonoma/Mendocino County line (38° 46.125’ N latitude). Following this recommendation, California Department of Fish and Wildlife (CDFW) Director Charlton H. Bonham has delayed the opening of the recreational Dungeness crab fishery in northern California. Recreational take and/or possession of Dungeness crab is prohibited in these closed waters.

Del Norter Who Spearheaded Fight to Reopen Rockfish Fishery Optimistic About Future Seasons

Andrea Spahn brought a rare piece of good news to the Del Norte County Board of Supervisors and the Crescent City Harbor District last month — the quillback rockfish is “not even close to being overfished.”

New data NOAA scientists presented at the Pacific Fishery Management Council’s Stock Assessment Review, or STAR, panel in June may mean local fishermen can pursue rockfish up to 30 fathoms from shore, further than the current 20-fathom boundary they’re limited to, Spahn told Redwood Voice Community News on July 1.

The STAR panel must finalize the data and the PFMC still needs to view it, but Spahn was confident that Del Norte anglers would win back what they lost nearly two years ago.

EPIC Offshore Wind Panel Stirs Little Local Interest

Only about a dozen Del Norters showed up on a cold Friday evening to hear the latest science concerning offshore wind energy’s potential impact on marine wildlife. The event, held in the United Methodist Church in Crescent City and hosted by the Environmental Protection Information Center (EPIC) of Arcata, was billed as an Offshore Wind Information Panel. Featured speakers addressed the possible interaction between marine mammals, birds and turtles and the giant floating wind turbines proposed for the waters off Del Norte and Humboldt counties.

Before the presentations began, Tom Wheeler, executive director of EPIC, explained the purpose of the event to Redwood Voice. “Under the Biden administration, Del Norte county was slated to have an offshore wind lease executed in the next four years. That’s obviously in question now with the Trump administration, but it’s still important for us to have these conversations and to understand the potential benefits and costs of offshore wind. And so we’re here tonight to help the community have that conversation.”

Cal Poly Humboldt Prof. Discusses Why Today’s 7.0 Temblor Spawned A 6-8 Inch Tsunami In Crescent City

Lori Dengler said she wasn’t surprised that Thursday’s magnitude 7.0 earthquake only produced a tsunami that topped out at roughly 8 inches in Crescent City.

But, while Dengler, geology professor emeritus at Cal Poly Humboldt, is still going through the reports and is speaking with the media about today’s temblor, she said one of the outcomes might be a rethinking of how the U.S. approaches tsunami evacuations.

“The Tsunami National Warning Center in Palmer, Alaska has developed a template for if an earthquake happens here and it’s in this magnitude range, this is what we do,” Dengler, whose expertise is in geophysics, earthquake and tsunami hazards and hazard reduction, told Redwood Voice Community News on Thursday. “Because this earthquake was so relatively close to the coast and their preliminary magnitude was 7.3, it immediately triggered a tsunami warning from basically Santa Cruz to Central Oregon.”
