[ARCHIVED] King Tide Community Observation Event on January 2, 2018

KT Guide Small copy

Three days of high tides will begin on January 1, with a King Tide event on January 2 at 11:37 a.m.  

King Tide is the term for an especially high tide event.  They occur naturally and regularly, and are predictable, but when they occur during heavy storms or flooding, water levels can rise even higher and cause even greater flooding.  Even with no extraordinary rainfall, a King Tide can help us get an idea of what a permanent rise in sea levels might look like in our communities.

The City is asking for our community’s help in documenting the King Tide in particular, with photos that show the effect of high tides in Arcata.  We have prepared a King Tide Guide which shows 15 impacted locations identified by City staff, but we are eager to see photos from other locations as well - especially creeks and streams.  The guide can be found at City Hall, at the Arcata Marsh Interpretive Center, and on the City’s website.

Photos can be uploaded to a story map at the City's website.  The story map shows photos and locations where they were taken. It’s very easy to use.  Just go to the Sea Level Rise page at to find the story map and for more information.

Crowdsourced documentation of Sea Level Rise impacts will be invaluable in the short term as City staff gathers information in anticipation of a City Council study session in the Spring.

This is the first of annual King Tide events that will record tidal impacts in specific places over a span of years.

The weather is predicted to be good – some clouds but no rain – and we invite the community to start 2018 with phones and cameras to help us create a visual record of King Tide impacts.
