Interactive Sea Level Rise Scenario Map

Sea Level Rise
Created: 06 January 2026
Screenshot of sea level rise map with link to the interactive mapHas Saturday's highest King Tide on record gotten you wondering how our neighborhoods, roads, and open space will fare as sea level rises? Now you check out our interactive map of two sea level rise scenarios for the Humboldt Bay Area! Featured are scenarios showing 1- and 2-meters above Year 2000 water levels. For many years, these have been static maps with no simple way for the public to examine points of interest. Now, people wondering if their neighborhood is at risk can zoom in on locations and see street names, etc. 
King Tides are usually a time to consider how high a typical high tide will be with one foot of sea level rise, but this weekend's high tides were nearly three feet higher than the Mean Higher High Water at the North Spit. Note that this is the preliminary water level from the National Weather Service, which will verify that figure in a few weeks.

Created: 03 November 2025
Humboldt County's new Outdoor Lighting Ordinance has many people asking, “How can I protect the night sky?”
To protect the night sky, choose lighting that is fully shielded, directed downward, and turns off when not needed. Brightness is 1,000 lumens or less, and the color temperature is warm (2,700 K or less).
For info on adding shielding to existing fixtures, buying fully-shielded fixtures, and more, check out our new flier: How to Protect the Night Sky & Prevent Light Pollution!

Created: 25 August 2025
We are excited to announce the first digital version of the Humboldt Bay Water Trail map! The original Water Trail Map was developed by Redwood Community Action Agency in 2004.
Humboldt Waterkeeper has breathed new life into the map, updating it with more accurate data on tidal mudflats and channel depths from NOAA’s navigational charts, and crowd-sourcing updates on the best boat launches.
You can download our georeferenced PDF for mobile apps like Avenza, or access the interactive webmap directly in any browser.

Mercury in Local Fish & Shellfish
Created: 15 July 2021
Our second study of mercury in local fish focused on nine species from nearshore coastal waters, including Pacific Halibut and several species of rockfish. We also sampled more Lingcod and California Halibut to add to the findings from our 2018 study. We found that most local fish are safe to eat in moderation—with a few exceptions.
