Hazardous Algae Blooms (0)
WTLA reports federal, state and regional source data on stream flows, groundwater levels, oil and other hazardous materials spill incidents by watershed, along with reporting hazardous algae blooms, algal toxin alerts at recreational freshwater bodies and in drinking water reservoirs. Information in this report is presented in the watershed area of occurrence, based on the location given by the source.
With The Flow describes Louisiana rivers, bayous and tributaries from headwaters to outlet. Locate your “home body” (the river or bayou nearest where you live) to see where the flow originates, how high it has to be for minor flooding to occur. Log in to USGS Waterwatch current streamflow for real time measurements at the monitoring station nearest you and sign up there for high flow alerts.
Flow volume can change rapidly during storms and rain events. Streamflow data is subject to review as sensors at the monitoring stations do malfunction from time to time. Refer to USGS Provisional Date Statement for more information.
Groundwater Monitor: USGS Groundwater Watch site has been removed, groundwater test wells are no longer measured and posted. WTGA will bring updates as USGS upgrades their monitoring system.
Impaired Water Bodies (IWB) 303d List
The Clean Water Act (CWA) Section 303(d) Program provides a mechanism for integration of implementation efforts to restore and protect the nation’s aquatic resources. Through this process the nation’s waters are assessed, restoration and protection objectives are systematically prioritized, and Total Maximum Daily Loads (TMDLs) and alternative approaches are adaptively implemented to achieve water quality goals with collaboration of State and Federal agencies, tribes, the regulated community, and the public.
New Vision of the CWA 303(d) Program
A new long-term vision for assessment, restoration, and protection under the CWA 303(d) Program for 2016 through 2022 (new vision) has been described whereby states may identify and prioritize watersheds for these restoration and protection efforts under the CWA 303(d) Program. The primary goals of this new vision of the CWA 303(d) Program include prioritization, assessment, protection, alternatives, engagement, and integration. The new vision will guide the realization of our clean water goals in a manner that recognizes lessons learned from the past two decades of CWA 303(d) Program implementation and addresses new challenges with innovative solution.

Hazardous Algae Blooms (HABs) Beach Alerts
Cyanobacteria are commonly referred to as blue-green algae; dense accumulations of toxin-producing cyanobacteria are referred to as “hazardous algae blooms”. Toxins may be present both before and after cyanobacteria are observed. WTLA posts the latest HABs reports around the state in the watersheds where they are occur.
Call Louisiana State Police 1-225-925-6595 within 1 hour of the spill incident.
call LSP HAZ MAT hotline 1-877-925-6595 or 225-925-6595
*The hazardous materials hot line is staffed by the Right-to-Know Unit and is the reporting point to the LSP for a chemical spill or emergency. Any transporter, manufacturer, storage facility, or anyone involving the handling of any regulated hazardous material must contact the LSP immediately to report any spillage or threat to public safety.
National Response Center (NRC) at 1-800-424-8802
24-hour emergency line staffed by US Coast Guard for oil spills on water.
An emergency spill situation is defined as any condition that could reasonably be expected to endanger the health and safety of the public or cause significant adverse impact to the environment.
For non-emergency spills:
Call Louisiana Department of Environmental Quality (DEQ) 24 hour Hotline 1-225-342-1234
Or, SPOC office line 1-225-219-3640 (within 24 hours of the spill, follow up with a written report in 7 days)
WTLA gathers data from LA DEQ, LADH, USGS WaterWatch, USGS Groundwater Watch, the National Weather Service, National Oceanographic and Atmospheric Administration (NOAA) sources. Our accuracy is dependent on these sources.
Louisiana's oil spill rules generally follow the federal standards.
Any unauthorized spills of one barrel (42 gallons) of oil or more is considered the reportable amount. These and spills of unknown amount must be reported to DEQ within 24 hours, or in the case of an emergency event, see above, call State Police immediately.
All reportable spills (emergency or not) must be followed up within 7 days with a written report. Consult with LA DEQ for guidance on detailing your spill incident, check the national requirements for reporting oil spills, and LA release notification requirements. Seek out information on Spill Prevention Planning.
“oil” includes but is not limited to: gasoline, crude oil, fuel oil, diesel oil, lubricating oil, sludge, oil refuse, oil mixed with wastes, and any other petroleum related product.
“chemical” spills include all toxic substances, note “Any transporter, manufacturer, storage facility, or anyone involving the handling of any regulated hazardous material must contact the LSP immediately to report any spillage or threat to public safety.” Refer to LA Department of Health Environmental Epidemiology and Toxicology page for more information on reporting (https://ldh.la.gov/page/834)
Note that all spills must be cleaned up, whether or not they are reportable.
The OEC Surveillance Division protects the citizens of the state by conducting inspections of permitted and non-permitted facilities, by responding to environmental incidents such as unauthorized releases, spills and citizen complaints, natural disasters, and other emergency situations, by providing compliance assistance to the regulated community when appropriate, by assessing and monitoring air and water quality for compliance with standards, and by promoting case information management for vigorous and timely resolution of issues of non-compliance.
