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 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.

Waterkeepers host paddles, swims, stand-up paddle, kayaks 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 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.
