Water news for Wednesday, January 31, 2024 - last updated 923 pm CST
Flood Update from USGS real-time streamflow monitoring stations around the eight watersheds of Louisiana
7 stations remain in active flood stage Wednesday night.
In Region 1, Bayou Bodcau gained another half a foot through the day, the rising trend continues Wedneday night. The current water level near Shreveport is more than seven feet over flood stage.
.
Bayou Dorcheat finishes Day 9 flooding near Springhill on a slow and steady declining flow trend. Downstream at Minden station, Bayou Dorcheat flooding continues with a slower decline curve, currently running 16.86 ft deep, flood stage is 14 ft. At the slow rate of decline, flooding can be expected to continue into the weekend.
Watershed Region 4 Sabine River is still flooding near Ruliff TX, still running three quarters of a foot over and not slowing down at all. The flow trend is level if not slightly increasing. Calcasieu River is still more than a foot and a half over flood stage at Glenmora and rising.
Region 5 Bayou Nezpique flooding subsided around 915 tonight, the flow level is just a hair under flood stage and receding at a steady pace.
In watershed Region 7 northeast LA, Pearl River continues to overflow its channel at Bogalusa, getting higher through the day and still rising, more than two and a half feet over by Wednesday night. Bogue Chitto tucked in under flood stage around noon as anticipated, presently half a foot below flood stage and still receding. Pearl River flow appears to have leveled off and may have peaked just short of moderate flood stage at Pearl River. There is no indication of decline in the water volume yet.
Check black tags for flood, blue tags for 99th percentile flows with levels updated through the day.
Drought Map from USGS 7-day average streamflows compared to historic averages
Louisiana drought map remains completely blank since Sunday. With 7 stations still recording active flooding, the 7-day streamflow averages in all parts of LA are higher than the seasonal average values for each location, meaning that no part of the state shows on the USGS drought map.
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.
