Lesser Slave Lake is located in northern Alberta, Canada, northwest of Edmonton.

Due to its location on a major fly-way for migrating birds, Lesser Slave Lake is popular with birders.

A number of Indian reserves are established at the shores of the lake: On February 14, 1968, a Cessna 182H CF-WUK plane crashed into the lake due to ice forming on the wings and causing the pilot to lose control.

The pilot was a Graham James Cox, a former 501 Squadron Commander during the Second World War.

On the one-year anniversary, a park at Canyon Creek was named in Deba's honor.
