Florida Lakes


Water quality for a sample of lakes in Florida


A dataset with 53 observations on the following 12 variables.

ID An identifying number for each lake
Lake Name of the lake
Alkalinity Concentration of calcium carbonate (in mg/L)
pH Acidity
Calcium Amount of calcium in water
Chlorophyll Amount of chlorophyll in water
AvgMercury Average mercury level for a sample of fish (large mouth bass) from each lake
NumSamples Number of fish sampled at each lake
MinMercury Minimum mercury level in a sampled fish
MaxMercury Maximum mercury level in a sampled fish
ThreeYrStdMercury Adjusted mercury level to account for the age of the fish
AgeData Mean age of fish in each sample


This dataset describes characteristics of water and fish samples from 53 Florida lakes. Some variables (e.g. Alkalinity, pH, and Calcium) reflect the chemistry of the water samples. Mercury levels were recorded for a sample of large mouth bass selected at each lake.
