Kahshe is the fourth largest lake in the region and has approximately 600 cottages.

The lake name Ka-shesheb-agam-ag is a First Nations term that may mean 'where there are-ducks-lake-place', thus 'Lake of Many Ducks'; compare Ojibwe jishib 'duck'; the following are spurious (Carl Masthay, St. Louis, 2009): Kah-Lake, She-Many, Bog-Ducks,a-and, Mog or Maug-Loons, therefore Lake of Many Many Ducks and Loons (researched by Ken Little).

Kahshe Lake has been featured on fishing shows and in a Tim Hortons television commercial.

Residents have been staging the Kahshe Lake regatta, for over fifty years.

[2] Lake Kahshe also has barn dances, a Labour Day concert, and the Rockhaven Inn craft sale.
