The regional lake sediment and water survey for central Ontario (north half of NTS 31E and parts of 31K and 31L) was conducted during the summer of 1988.

This report presents analytical and statistical data for 18 variables in lake sediments from 1,225 sample sites, collected at an average density of one sample per 16.7 km². This report includes values for uranium, fluoride, pH, alkalinity, calcium and magnesium in waters.
