The regional lake survey for northeastern Alberta (Parts of NTS 74E, 74L and 74M) was conducted during the summer of 1993.

This report presents analytical and statistical data for 35 elements in lake sediments from 1160 sample sites, collected at an average density of one sample per 19 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are included in this report.
