State of Louisiana Water Quality Management Plan
Water Quality Inventory Integrated Report
(Section 305(b) and 303(d) Reports)
The Integrated Report (IR) is the current form of biennial reporting of the status of Louisiana waters. The IR is made up of what was once called the 305(b) Water Quality Inventory Report and the 303(d) List of Impaired Waterbodies. One of the primary focuses of the IR is on the use of five categories and three subcategories to which waterbodies or waterbody/impairment combinations can be assigned. Categorization under IR guidance allows for a more focused approach to water quality management by clearly determining what actions are required to protect or improve individual waters of the state. The IR categories and definitions can be found at the link below. Other changes resulting from U.S. EPA's IR guidance can be found in the 2002 Water Quality Inventory, Executive Summary.
