The regional lake survey for Lynn Lake, Manitoba (NTS 64C) was conducted during the summer of 1983.

This report presents analytical and statistical data for 15 elements plus loss-on-ignition in lake sediments from X sample sites, collected at an average density of one sample per 13 km². Uranium, fluoride, pH, calcium, magnesium, iron and alkalinity values in concomitant waters are also included in this report.
