Today, these organizations have built a global network, the Waterkeeper Alliance, and include more than one hundred eighty Keepers, modeled after and supported by Riverkeeper. Despite the national and global transformation of the Keeper movement, Riverkeeper's mission remains local. Their efforts still focus on reducing fish kills and water pollution, maintaining the quality of New York City's drinking water, and increasing public access and appreciation for the Hudson River. At any given time, Riverkeeper is involved in many actions to protect the integrity of the river, its tributaries, the Croton watershed, or other waters that affect New York City's water supply. These actions take the form of litigation; investigations; environmental review of development projects; citizen empowerment projects; regulatory review and comment; and local, state, and federal policy issues.
