The regional lake sediment and water survey for northern Ontario (NTS 42D and south half of 42E) was conducted during the summer of 1977.

This report presents analytical and statistical data for 13 variables in lake sediments and three variables (U, F, pH) in lake waters from 915 sample sites, collected at an average density of one sample per 13.7 km².
