The park has removed three other high mountain dams. In 1988, the park removed rock and dirt dams at Sandbeach and Pear Lakes, and then regraded the land to the original slope. In 1989 and 1990, five million pounds of concrete and rebar were removed from the Bluebird Lake dam and flown out of the backcountry. The materials were recycled near Lily Lake. About 27 hectares of shoreline around all three lakes were re-exposed, and the park is currently allowing the shores to restore naturally, with minimal supplemental planting. Park staff planted willows along the outlet stream of Sandbeach Lake to create spawning habitat for greenback cutthroat trout. The fish were reintroduced in the lake after the dam was removed.
