Swimmable Waters

California Coastkeeper Alliance works to protect our waters so that they are clean and safe for swimming, surfing, paddling, fishing, wading, and frolicking. Join us each year on July 25th – Swimmable California Day – to celebrate all of California’s healthy waters and the regulations that protect them.

Upload a photo of how you enjoy California waters on Facebook, Twitter or Instagram with the hashtag #SwimmableCA.

Check out what’s going on in your local watershed on Swimmable California Day – Waterkeepers often host paddles, swims, and other events to get people out on the water.


Learn how you can team up with your local Waterkeeper to fight water pollution, clean up a local beach, or restore the aquatic habitat your area.

California Waterkeepers offer a diverse number of ways to keep your local waters clean and swimmable including water quality monitoring, coastal, bay and river cleanups, surveying underwater parks (MPA Watch), capturing ultra-high tide “king tides” events, volunteer dive restoration and research, photo and video documentation. Many Waterkeepers offer education and volunteer experiences for schools and businesses, as well as individuals.
