The Louisiana Department of Environmental Quality (LDEQ) has launched a new interactive map that details the water bodies included in the Louisiana Water Quality Integrated Report. The Louisiana Water Quality Integrated Report (IR) is the current format for the state’s biennial reports on the water quality of Louisiana surface waters. The most current Water Quality Integrated Report, considered final and approved by the U.S. Environmental Protection Agency, is the 2018 report, which can be viewed via an interactive map on the app. The IR, formerly known separately as the 305(b) Report and the 303(d) List, is a requirement of the federal Clean Water Act. It is developed every even-numbered year and submitted to the EPA for approval of the 303(d) List portion of the report.
