 life, and the boundary between the Chumash tribes, who lived to the northwest, and the Gabrieliño, to the south and east, was there.

The origin of the creek's name likely derives from the Chumash term U-mali-wu, which means "it makes a loud noise there". The Spanish recorded this as 'Malibu', and this spelling appears in the Topanga Malibu Sequit land grant on July 12, 1805..

, and Malibu Creek. Genetic analysis of the steelhead in all four of these watersheds has shown them to be of native and not hatchery stocks. A sand berm across the mouth of the Malibu Creek Lagoon blocks the stream to ocean-based steelhead except during the rainy winter season when high flows breach the berm and opens access to the estuary. The fish quickly reach an impassable barrier presented by the 30 meter high Rindge Dam

, restricting them to the lowest 3.2 km of more than 112 km of historic steelhead habitat. The dam, originally built for water storage and flood control in 1926, no longer functions as the reservoir is completely filled with sediment. Over the past decade several government agencies and non-profit organizations have been trying to remove the dam to restore access to upstream spawning habitat. In 1997, the southern Evolutionarily Significant Unit (ESU) of steelhead trout was added to the federal list of endangered species, with Malibu Creek as the southernmost boundary. Since 1997, the protected range of this ESU has been extended to the U.S./Mexican border. The National Marine Fisheries Service (NMFS) estimates that only 500 anadromous adults remain within this ESU (NMFS 2007). In summer, 2006, there was a massive die off of native and exotic fish and invertebrates in Malibu Creek, thought to be due to a combination of pollution, high temperatures and low oxygen. The steelhead trout population fell to zero by November, 2006. Fortunately, surveys in summer 2008 documented five returning adult steelhead (over 50 cm) and over 2,200 smolt

Malibu Creek Watershed

Malibu Creek has several tributaries draining the Santa Monica Mountains. These include streams draining to Lake Sherwood, and thence via Potrero Valley Creek to Westlake Lake, then down Triunfo Creek to its confluence with Lobo Canyon Creek which is the origin of Malibu Creek. Amongst many other tributaries are Medea Creek, Las Virgenes Creek and Cold Creek. Medea Creek and Malibu Creek join to form Malibu Lake. Further downstream Las Virgenes Creek joins Malibu Creek at Malibu Creek State Park
