Dickson Dam is a sightseeing destination on the Red Deer River located west of the community of Innisfail, Alberta, Canada. The construction of the dam created Gleniffer Lake.
Gleniffer Lake is fed by the Red Deer River and measures 7 kilometres long and 2 kilometres wide. It was named after a post office that once serviced the area long ago. The post office stood on the same site as the present day dam.
