Santiago Creek

Santiago Creek is a major watercourse in Orange County in the U.S. state of California. About 34 miles (55 km) long, it drains most of the northern Santa Ana Mountains and is a tributary to the Santa Ana River. It is one of the longest watercourses entirely within the county.

Historically the Santiago Creek provided water for the Tongva Native American group, whose territory extended over much of northern present-day Orange County and into the Los Angeles Basin. Native Americans have inhabited the Santiago Creek and Santa Ana River watershed for at least 12,000 years. The creek was named by the Spanish Gaspar de Portolá expedition of 1769, which crossed the Santa Ana River near the Santiago Creek confluence. A tributary of the creek was the subject of a short-lived silver boom in the 1870s. Present-day Santiago Peak shares its name with the creek. Irvine Lake dam was constructed in 1929, marking the end of the creek's free-flowing state. The creek now contributes a small amount to the municipal water supply of Orange County via pipelines from Irvine Lake.

The Santiago Creek watershed covers about 100.6 square miles (261 km2) in northern Orange County. Much of the upper course of the creek remains in its natural state, while the lower section is now urbanized and includes parts of the cities of Tustin, Orange, and Santa Ana. The creek above Lake Irvine is perennial, but below the lake, the ephemeral creek runs in a channelized course. Along the course of Santiago Creek, there are many recreational areas, including the Cleveland National Forest and Irvine Regional Park.

    The only law was that enforced by the Creek Lighthorsemen and the U.S. deputy marshals who paid rare and brief visits; or the “two volumes of common law” that every man carried strapped to his thighs.
