Hazardous Spills
Louisiana Department of Environmental Quality responds to reports made to the Emergency Spill line. A massive spill incident in November 2023 is still under investigation by the US Coast Guard, federal EPA and state DEQ authorities. A million gallons of crude oil discharged into the Gulf of Mexico from a pipeline coming off seven oil production platforms. The platforms and pipeline were shut down immediately and remain shut down as the investigators have not determined where the leak occurred. US Coast Guard personnel told WTLA.us that there is no update on the case, it remains under investigation. A recent report investigated by LDEQ involved an unknown amount of diesel fuel spilled at a boat launch in Amelia in the month of February. Spills are tagged in pink by location on the maps and listed under the spill button to the right of the map.
USGS Provisional Data Statement
Data are provisional and subject to revision until they have been thoroughly reviewed and received final approval. Current condition data relayed by satellite or other telemetry are automatically screened to not display improbable values until they can be verified.
Provisional data may be inaccurate due to instrument malfunctions or physical changes at the measurement site. Subsequent review based on field inspections and measurements may result in significant revisions to the data.
Data users are cautioned to consider carefully the provisional nature of the information before using it for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences. Information concerning the accuracy and appropriate uses of these data or concerning other hydrologic data may be obtained from the USGS.
