WT HAB Tracker from the satellite monitoring program of National Centers for Coastal Ocean Science (NCCOS)
The latest image of Louisiana southeast water bodies is clear, captured Oct 25 at 7.6 mph. Lake Boeuf is the hot spot again, the lakewide HAB runs north of 2 million cells per ml, likely accompanied by a serious cyanotoxin load. Lakes Verret and Palourde lakewide bluegreen blooms 800 to 900 thousand cells per ml, Lac des Allemands and Bayou Fortier lakewide HABs 800 thousand cells per ml. Black Bay remains full of bluegreen at 700 to 800 thousand cells per ml. Lakes Pontchartrain and Maurepas appear clear of HAB. See the latest satellite image of southeast LA water bodies, here.
