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. These data are in spreadsheet form.
