Swim Guide is an award-winning app that lets you find the best swimming holes, rivers, and beaches. You can search and browse our vast database of over 7,000 locations and get real-time alerts when the water quality fails to meet the standards set by the government and health agencies.

You can also report water quality issues to the organizations responsible for the locations you find.

Swim Guide is a non-profit, volunteer-run organization. Most of their funding comes from user fees, meaning they're to help you.

The app is always free to use, but they do have a paid service called Swim Guide Pro. With it, you can get more detailed information, report issues with a higher level of accuracy, and you can get alerts for more locations.
