Survey Description


In the summer of 2000, a high-density lake sediment and water quality survey was carried out in the Perrault Falls area, northwestern Ontario as part of Operation Treasure Hunt.

A total of 1262 lake sites were visited for an average density of 1 sample per 5 km 2.  Lake sediment samples were collected at 1124 sites.

The data are published in Ontario Geological Survey Open File Report OFR6092 and Miscellaneous Release-Data, MRD106.

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