The regional lake sediment and water survey for central Ontario (NTS 41I and part of 41H) was conducted during the summer of 1987.

This report presents analytical and statistical data for 18 variables in lake sediments from 1,451 sample sites, collected at an average density of one sample per 15.1 km². This report includes values for uranium, fluoride, pH, alkalinity, calcium and magnesium in waters.
