The regional lake survey for southeastern Yukon (NTS 105A) was conducted during the summer of 1993 .

This report presents analytical and statistical data for 36 elements in lake sediments from 205 sample sites, collected at an average density of one sample per 27.25 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are included in this report.
