HAPPENING NOW
Ville Platte planned outage and BWA Monday Feb 12
Flooding rivers slowing down Friday

Water news for Friday, February 9, 2024 - updated 615 pm CST

Drinking Water Matters
Ville Platte has announced a BWA upcoming for all customers next week. The water tower is to be drained and refilled on Monday February 12. Following the resumption of water service, a BWA will be in effect until potable water testing confirms the system clear of microbiological contamination.

Cecilia came under BWA following a water main break Wednesday. The boil advisory applies to customers in several areas, more to follow. Cecilia is a census designated place in St Martin Parish.

Flood Update from USGS real-time streamflow monitoring stations throughout Louisiana

Five locations remain above flood stage Friday.

In Region 1, Bayou Dorcheat flow is coming down slowly, running five inches above flood stage near Springhill. Bayou Bodcau water declined by a little more than two inches through Friday, still well over eight and a half feet above flood stage near Shreveport.

Watershed Region 4 Sabine River is in a holding pattern, exactly six inches over flood stage near Ruliff, TX.

Pearl River came down about two inches Friday, just above a foot and a half over flood stage now near Bogalusa. Downstream at Pearl River, the water level is more than two feet above flood stage.

Check black tags on the map for flood levels, provisional data courtesy of the USGS streamflow sensors placed into LA rivers, bogues and bayous.

Drought Map from USGS 7-day average streamflows compared to historic averages
Louisiana drought map remains blank since Sunday, Jan 28.

HAB Update from National Centers for Coastal Ocean Science
The latest sat photo from NCCOS was taken yesterday, Feb 8 at wind speed 3.1 mph. This image is completely cloud covered. We refer back to the image of Feb 7 which was a clear view of Lake Pontchartrain, Lake Maurepas, Lac des Allemands, Bayou Fortier, Lake Cataouache, Lake Salvador and Lake Lery. The latest image was captured by Copernicus satellite Feb 7 at low enough wind speed to rely on the estimation of the HAB extent, 3.7 mph.

Lake Pontchartrain, Lake Maurepas, Lac des Allemands, Bayou Fortier, Lake Cataouache, Lake Salvador appear HAB-free even at low wind speed on Feb 7 image. Lake Lery appears with a widespread HAB filling the east end of the lake at 800 or 900 thousand cells per 100 ml, a high concentration.

Note WaterToday reports day-to-day changes recorded by USGS streamflow monitors on rivers and tributaries located in Louisiana, along with monitors upstream in the Mississippi River basin: Ohio, Georgia and southwest New York state. USGS creates a drought map from 7-day average streamflow readings, by comparing the average with the historic weekly normal flow value for each location. The drought ratings are below normal, moderate hydrologic drought, severe drought and extreme drought.

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.
