Tumtum Lake
Tumtum Lake is a small lake located in the Upper Adams River valley in the Interior of British Columbia, Canada. It is a popular fishing lake, containing rainbow trout, bull trout, and whitefish. "Tumtum" is a Chinook Jargon word for "heart", or the "pulsing of the heart", and may refer to the sound of the waterfalls on the Upper Adams River downstream from the lake. References
