Visitor information and official guide to Pyramid Lake boat rentals and watercraft recreational activities offered by the premier provider of high end wakeboard and water ski boats. Pyramid Lake is a reservoir formed by Pyramid Dam on Piru Creek in the eastern San Emigdio Mountains, near Castaic, Southern California; however this lake is much smaller that Castaic causing it to get crowded on the weekends and holidays.
The earth and rock dam was built by the California Water Resources and was completed in 1973. Pyramid Lake is part of the California Aqueduct, which is part of the California State Water Project. Outflow goes downstream to Castaic Lake which is a much larger holding facility.
The name of the lake comes from the Pyramid Rock, created when a ridge was cut through in 1932 by the Ridge Route Alternate. Pyramid Rock still exists directly in front of the dam bringing many visitors to see the beauty.
Pyramid Lake allows boating, fishing, jet skiing, and picnic areas; including private areas around the lake which can be accessed by boat only. There and courtesy docks for use. Vista del Lago Visitors Center overlooks the lake. Access is from Interstate 5, please be aware of the park regulations before coming as there is restrictions on what you can bring in the park.
