Land and Water Conservation Fund Water Amendments Act of 2023

This bill amends the Land and Water Conservation Fund to allow states to use federal funds for water quality projects that restore impaired rivers, wetlands, and other natural water systems. It directly affects states with existing water quality control plans under the Clean Water Act, enabling them to apply for funding for projects like wetland restoration or nutrient load reduction. Key provisions define "water quality projects" as those restoring impaired waters identified under federal law, require consultation with the EPA, and prohibit using funds to reimburse already-completed work. The bill does not expand federal authority over waterways or create new regulatory powers.
