Lake Gregory, Recreational lake in Crestline, California.
Lake Gregory is a reservoir in the San Bernardino National Forest, next to Crestline. It was formed by damming the east and west forks of Houston Creek, and Lake Drive crosses the dam at its edge. The lake covers about 0.33 square kilometres, with a shoreline of grey rocks, grass and trees rising into the hillside.
Arthur Gregory Sr. created the lake in 1937 through a Works Progress Administration grant, renaming the former Houston Flat area after himself. The project was part of a broader federal effort to develop local resources during that era.
The lake's name comes from Arthur Gregory Sr., the Redlands citrus grower who financed the dam's completion. The regional park hosts Crestline's Independence Day celebration, and the south shore is a popular fishing spot. On the southeast shore, the San Moritz Lodge's Tyrolean-style clubhouse, built in 1950, now serves as a restaurant for events such as weddings.
The area has separate entrance areas for different activities, and boat rentals and water equipment are available from May through September. It helps to visit during the warmer months when most facilities are operating.
Heavy rainfall in March 1938 filled the entire lake within three days, contrary to the three-year filling period that planners had expected. This rapid completion was an unexpected benefit for the newly created body of water.
