Why This Map Matters

  • Public Health First: Nobody should get sick from visiting or living near local rivers. This map reflects water quality data that helps keep recreation safe.
  • Protecting a Public Resource: The LA River is a public asset, a potential park space, and a wildlife corridor, not a sewer. This map helps highlight water quality issues and the need for greater protection.
  • Community Action & Awareness: Increased visibility and accessible data empower everyone to participate in protecting the river for ourselves, wildlife, and future generations.
