Flood Update from USGS real-time streamflow monitoring stations around the eight watersheds of Louisiana
In Region 1, Bayou Dorcheat continue to overflow .83 feet over flood stage near Springhill. Bayou Bodcau water level rose slightly overnight, running more than nine feet above flood stage near Shreveport.
Watershed Region 4 Sabine River is on a steady receding curve, running half a foot over by Tuesday noon. Calcasieu River came down inches overnight, running half a foot over flood stage, steadily declining.
Pearl River is slightly more than two feet above flood stage at Bogalusa. At Pearl River, the water level is dropping, still above two feet over. More to follow.
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
NCCOS has a new photo out of the southeast Louisiana water bodies including Lake Pontchartrain, Lake Verret, Lake Palourde and many more. The image captured Feb 5 at wind speed 24.3 mph. With high wind, the HABs can become submerged and escape detection by the satellite full color imaging. Our last clear image was captured on Feb 4 showing a blazing HAB filling the east half of Lake Lery HAB at a high concentration 700 thousand cells per 100 ml.
Drinking Water Matters
Livingston, Morehouse, Slidell have BWAs issued Feb 1. See yellow tags on the map to the right for details.
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.
