Secchi = Secchi disc transparency in meters (m); Chl a = chlorophyll a in micrograms per liter (µg/L); TP = total phosphorus in µg/L; TSI(Secchi), TSI(Chl a), TSI(TP) = Wisconsin trophic state index based on Secchi, Chl a, and TP, respectively; Diss. Si = dissolved silica in µg/L; Alkalinity = alkalinity as total CaCO3 in milligrams per liter (mg/L);
