The Hollywood Sign overlooks the reservoir and the adjacent neighborhood. The reservoir was constructed by the Mulholland Dam, which was erected in 1924 and intended as part of the city's water storage and supply system by the Los Angeles Department of Water and Power, formerly known as the Bureau of Water Works and Supply. The sign is made of steel and was painted gold in 1990 to celebrate its 20th anniversary.
The Mulholland Dam creates a lake that covers about 2.5 square miles and has a maximum depth of 40 feet. The lake provides drinking water for nearly two million people in Southern California. It also supports a diverse population of fish, including koi and bass, and offers excellent fishing for all ages.
Visitors can tour the Mulholland Dam Reservation any time during the day but must go through a gate at the entrance to the parking lot. Guided tours are offered daily at 9:30 a.m., 11:30 a.m., 1:30 p.m., and 3:30 p.m.; an additional tour goes on at 4:30 p.m. if there are enough participants. The last tour leaves the reservation at 5:15 p.m.. Participants should bring their own photosensitive equipment. The tour takes about an hour and fifteen minutes per person.
The lake is open to swimming from mid-June to early September. Lifeguards are present in the summer months.

The Mulholland Dam is a dam built by the Los Angeles Department of Water and Power in the Hollywood Hills in Los Angeles, California. It creates a reservoir called Mulholland Lake that provides water for irrigation throughout the West Valley, as well as for industrial and municipal use.
The lake has two narrow entrances through which all its water enters and leaves. This helps maintain a constant temperature in the summer and winter because heat rises and water moves toward the lower elevation of the lake, so less energy is needed to warm or cool the water.
The lake itself is an important wildlife habitat with room for fish reproduction and escape from predators. In addition to being a popular place for hiking and biking, it is also known for its view of the San Fernando Valley and Hollywood Hills.
There are three main access points to the lake: one at the bottom of Mulholland Drive, another at the top and a third near the middle. The dam itself is about half a mile from the top entrance and carries out its function quite well; however, the other two entries are fairly small and do not provide much room for large vehicles. The lake itself is very wide at the bottom but gets narrower toward the middle.
