The regional lake survey for central Labrador (NTS 13K) was conducted during the summer of 1983.

This report presents analytical and statistical data for 15 elements in lake sediments from XX 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.
