Become a Waterkeeper

Waterkeeper Alliance unites more than 350 Waterkeeper groups on the front lines of the planetary environmental crisis, patrolling and protecting more than 2.75 million square miles of rivers, lakes, and coastal waterways on six continents.

From Alaska to the Himalayas, the Great Lakes to Australia, the Waterkeeper movement defends the fundamental human right to drinkable, fishable, and swimmable waters, and combines firsthand knowledge of waterways with an unwavering commitment to the rights of local communities.

Waterkeeper Alliance ensures that the world’s Waterkeeper groups are as connected to each other as they are to their local waters, organizing the fight for clean water into a coordinated global movement.

Types of Waterkeeper Groups


Waterkeeper Organizations are fully licensed, voting members of Waterkeeper Alliance, each representing a specific waterway. Waterkeeper Alliance offers a variety of training, organizing, communications, and advocacy benefits to strengthen their programs so that the local fight for clean water becomes a powerful, coordinated, global movement.


Waterkeeper Affiliates are non-voting, provisionally licensed Waterkeeper groups that represent a specific waterway. Affiliates can utilize Waterkeeper Alliance’s benefits to strengthen their programs and develop the capacity to become fully licensed, voting Waterkeeper Member Organizations.

Strengthening and growing Waterkeeper groups in the Amazon Basin

Through Project Osiris, Waterkeeper Alliance has prioritized the Amazon Basin as one of the world’s most iconic and endangered water bodies in critical need of protection. With an initial focus in Peru, Brazil, and Ecuador, we will recruit local and Indigenous-led groups to amplify their voices—and Indigenous knowledge—for the protection of the Amazon Basin and Rainforest.
