    • Map Layer: Lake Pontchartrain Beach Algal Bloom Monitoring during September 2019

    Metadata Updated: October 19, 2024

    Water quality data was collected by the United States Army Corp of Engineers at numerous locations along the shore of Lake Ponchartrain, Louisiana during the month of September 2019. The samples were collected repeatedly at 8 locations around the lake. The parameters collected include chlorophyll a (uncorrected), chlorophyll b, chlorophyll c1 + c2, phycocyanin, microcystin, water temperature, dissolved oxygen, dissolved oxygen percent saturation, pH, salinity, and specific conductance. These data were used to monitor the water quality of commonly used beaches and swimming areas. The full description of the dataset can be found within NCEI archive data with Accession 0225522.
