Mean, standard error (SE), minimum (Min), and maximum (Max) values for physical and chemical properties of water at 197 sites. Chlorophyll a, electrical conductivity, total dissolved phosphorus, nitrate nitrogen, and suspended solids are presented as mean values of monthly estimates from 2012 to 2015, water temperature is presented as the mean from May to October, and water depth and velocity data were obtained at the sampling date.
