In July 2005, a high-density lake sediment and water survey was carried out in the Red Lake area, northwestern Ontario.

Lake sediment and/or water samples were collected at 1157 sites, for an average density of 1 sample per 3.3 km².

The data are published in Ontario Geological Survey Open File Report OFR6198 and Miscellaneous Release-Data, MRD218.

The data are also part of a compilation database, Lake Geochemistry of Ontario – 2019.
