Two years ago, the U.S. Supreme Court slashed federal Clean Water Act protection of wetlands, streams, and all of our clean water with its decision in the Sackett v. EPA case. NRDC scientists mapped the potential impact of the Sackett decision and found it devastating—threatening harmful repercussions for droughts, wildfires, flooding, wildlife, and the drinking water supply. In the absence of federal protection, the imperative to defend our shared waters falls increasingly on individuals, states, and Native American Tribal Nations. NRDC is actively working to prevent any further weakening of the Clean Water Act (which the federal U.S. Environmental Protection Agency intends to pursue) and to ensure the law remains a robust tool for all wetland and stream advocates, including Indigenous Peoples. Tribal Nations protect and manage millions of acres of wetlands in the United States, and with commitments made by the U.S. government to Tribal co-management and co-stewardship of federal lands, the amount of clean water safeguarded by Tribal Nations is growing.
