The regional lake survey for west central labrador (NTS X23G, H, I and J) was conducted during the summer of 1978.

This report presents analytical and statistical data for 12 elements in lake sediments from XX 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.

The reconnaissance surveys were undertaken by the Geological Survey of Canada in conjunction with the Newfoundland Department of Mines and Energy under the terms of the Canada - Newfoundland Agreement on a Uranium Reconnaissance Program (1976 - 1982). Provincial Funding was financed through the Canada - Newfoundland Development Subsidiary Agreement (1976 - 1982).

E.H.W. Hornbrook directed the Geological Survey of Canada activities.

N.G. Lund was responsible for data management and open file production.

F. Williams of the Cartographic Section supervised map preparation.

Direct Photo-Head plotting facilities were made available through the Geological Survey of Canada and the Computer Science Centre, EMR.

Provincial Liason was with P.H. Davenport and B.A. Greene, Department of Mines and Energy, Newfoundland.
