The regional lake survey for north-west Manitoba (NTS 64G) was conducted during the summer of1984.
This report presents analytical and statistical data for 15 elements in lake sediments from 881 sample sites, collected at an average density of one sample per 13 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are included in this report.
