Thutade Lake is located in the Omineca Mountains of the Northern Interior of British Columbia, Canada.

The area is very remote, being located about 260 km (160 mi) north of Smithers, although several mining operations for ores containing copper, lead, zinc and silver have occurred around the lake.

[3][4] The largest of these is the Kemess Mine, an iron and copper property originally owned by Royal Oak Mines and now by Northgate Minerals, located in the valley of Kemess Creek, which is off the northeast end of Thutade Lake.

Just downstream from the outlet of Thutade Lake, the Finlay plunges over the 180-foot (55 m) Cascadero Falls,[5] and then through a series of cataracts in a twisting course until it begins its main northeastward trend.

Cascadero Falls is slated for hydroelectric development in connection with the power needs of the area's mines.
