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 on 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 five 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. IR categories are described in each of the Integrated Reports found below.
