Streamflow Situation from the network of USGS streamflow gauges in Louisiana
Streamflows run a mix of normal to much below seasonal normal Monday, the lower flows again appearing through northeast Region 3 watershed, central Region 5 watershed and east Region 7 watershed. Low flow volume continues in Bayou Macon coming out of Arkansas, this limiting the downstream flow to the Tensas River. Region 3 is now rated below normal with the Tensas River channel remaining in extreme hydrologic drought. Region 7 watershed is filling in on the drought map, below normal in all but the east half of St Helena and Livingston Parishes. Region 5 watershed has escalated to moderate drought over the weekend impacting Evangeline and Acadia Parishes. These Parishes were often the only part of Louisiana unrated while every other part of the state was in severe drought much of 2023. No flooding or high flows, no extreme low flows recorded as of this report.
WT HAB Tracker from the satellite monitoring program of National Centers for Coastal Ocean Science (NCCOS)
The latest image of Lake Pontchartrain and the southeast water bodies is dated Sep 29, a clear view of the water taken at wind speed 3.8 mph. HAB activity has declined substantially, Lakes Pontchartrain and Maurepas remain unburdened, Lac des Allemands and Bayou Fortier appear clear of HABs, as do Cataouache and Lake Salvador. Lake Verret widespread HAB remains locked into the south water at high concentration 800 thousand to 1 million cells per ml. Lake Palourde widespread HABs has settled into the north half of the water body matching concentration color scale for 800 thousand cells per ml. Black Bay widespread HAB is high concentration 900 thousand to 1 million cells per ml. See the latest satellite image of southeast LA water bodies, here.
