Flooding ended near Mooringsport
June 12, 2024 updated 102 pm CDT
Current Streamflow Situation
Streamflows continue to run much above seasonal normal to high in the west, with the number of flooding water bodies in the reference network down from ten to seven events recorded by Wednesday afternoon. An area of Region 3 watershed is rated severe hydrologic drought Wednesday following Tensas River channel catching the west edge of East Carroll, Madison and Tensas Parishes. Tangipahoa Parish in Region 7 remains on the drought map at below normal rating another day. No extreme low flows are recorded as of this report, see below for the flood update.
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Forty-two flood events are recorded on the national USGS network Wednesday afternoon, down from forty-five this morning. Two reference flood events have ended in Louisiana since the morning report, WT USA now tracking seven reference floods through the coverage area New York, Ohio, Georgia and Louisiana. At the writing of this report, all seven occurring in Louisiana.
Louisiana: Two more flooding incidents monitored by the Louisiana network of the USGS have ceased today. Region 1 Bayou Dorcheat is no longer flooding near Springhill, Bayou Bodcau Lake is still four feet over the basin near Shreveport and beginning to come down. In Region 2 watershed, Little River is back in the channel near Rochelle. Region 4 border Sabine River continues to flood near Logansport, Burkeville, Bon Wier and Ruliff. East Region 4 Calcasieu River is still a foot above the channel near Glenmora. Pearl River is still a couple of inches up over flood stage at the Town of Pearl River. Twelvemile Bayou is still running above 99th percentile near Dixie with no flood stage to reference. For more information on the flood trend in Louisiana, see black tags indicating flood flow volume and gauge height, blue tags for 99th percentile flows, updated daily on the map to the right.
Drinking Water Advisories
Calcasieu Waterworks District No. 2 (Mossville) issued a system-wide boil water advisory Monday following a water main break on Old Spanish Trail.
Jeff Davis Water District #4 reported a BWA issued Monday for the 19000 and 20000 blocks of Elton Drive near Hathaway and Jennings.
As many drinking water facilities are supplied from surface water reservoirs, the streamflow situation is pertinent to both drinking water supply and quality. High flows can stir up sediment and cause turbidity in the reservoirs, requiring additional treatments to render the water potable. Low flow volume is linked to warmer temperatures in the reservoir and can be an issue for water quality where HABs are present. WT tracks streamflow trends with an eye to the impacts on drinking water supply and quality in each of the state's watersheds. Check the watershed layer on the map to see the direction of flow and streamflows that may be impacting drinking water today.
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.
