The regional stream and lake sediment and water survey of the Whitesail Lake, British Columbia map sheet (NTS 93E) was conducted during the summer of 1986.

This report presents analytical and statistical data for 16 elements plus loss-on-ignition in stream and lake sediments from 898 stream sites and 214 lake sites, collected at an average density of one sample per 16 km² and 56 km² respectively. Uranium, fluoride, and pH values in waters from these sites are included in this report.
