The regional lake sediment and water survey in northwestern Ontario (NTS 052C) was conducted during the summer of 1979.
This report presents analytical and statistical data for 12 variables in lake sediments and three variables (U, F, pH) in lake waters from 510 sample sites, collected at an average density of one sample per 15.8 km².
