The regional lake survey for central Manitoba (NTS 63I and parts of 63H and 63P) was conducted during the summer of 1987.
This report presents analytical and statistical data for 17 elements plus loss-on-ignition in lake sediments from 1 699 sample sites, collected at an average density of one sample per 13 km². Uranium, fluoride, calcium, magnesium, alkalinity and pH values in concomitant waters are included in this report.

The reconnaissance surveys were undertaken by the Geological Survey of Canada in conjunction with the Manitoba Department of Energy and Mines under the Canada - Manitoba Mineral Development Agreement (1984 - 1989).
E.H.W. Hornbrook directed the survey.
P.W.B. Friske coordinated the operational activities of contract and Geological Survey of Canada staff.
H.R. Schmitt coordinated and edited open file production.
A.C. Galletta and D. Wright managed the digital geochemical data, provided computer processing support and developed software to plot the open file symbol and regional trend maps.
Computing services provided by the Computer Science Centre, EMR.
The plotting was done by Canada Lands Data Systems staff at Environment Canada, Hull, Quebec.
H. Gross developed microcomputer software to produce data listings and summary statistics.
