Reflection Lake Lying at an elevation of 5890 feet, Reflection Lake is located north of Lassen Peak near Manzanita Lake. It is named for its smooth waters which provide excellent reflections of Lassen Peak and the surrounding area. It has been known through history as Little Manzanita Lake, Mud Lake, and Stockton Lake. As with other land in the area it was once owned by Benjamin Loomis. At one time visitors used to ice skate on the lake when conditions allowed.
