Orange County’s Swamps & Marshes: A Historical Thumbnail Sketch

You’ll never hear it from the Chamber of Commerce, but much of Orange County – from Irvine to Seal Beach to Westminster – was once covered in swamps and marshes. In a few places, segments of these swamps can still be found. But more often, over a century of elaborate drainage efforts have obliterated most signs of the wetlands. Let’s look at a few lowland highlights:

The area southeast of Garden Grove was known as “the Willows” for the dense swampy thickets that trapped wandering cattle and hid fugitive criminals. Even after the dense tangle of willows was carved away, simply driving a pipe into the ground a short distance would send a geyser of water into the air. Fountain Valley took its name from this phenomenon.

The miles-wide, willow-clogged river delta between the Huntington Beach mesa and Costa Mesa was occasionally described as being part of “the Willows,” but was also known by other names, including Talbert Gap. This swampland providing bait for fishermen, and seclusion for moonshiners and hermits. It included numerous lagoons including the large “Bitter Water Lake.”

Westminster and north Huntington Beach were known as “the Peatlands” in the 1890s and early 1900s. Attempts were made to harvest peat from the bogs for fuel, and horses had to wear wide “peat shoes” to keep from sinking into the squishy ground. And the Cypress area was once called “Waterville” for its many artesian wells.

Peat shoes kept horses from sinking into the bog.

Gospel Swamp was the name given to the marshy land south of Santa Ana, below today’s McFadden Avenue and extending down into the northern edge of Costa Mesa. Many of the area’s settlers in the late 1800s were rural, religious folks from the South, who were jokingly called “Swamp Angels” by their city slicker neighbors in Santa Ana. The Greenville Country Church (1877) still stands at Greenville St. and MacArthur, near the heart of Gospel Swamp. A small remnant of the swamp itself can be seen behind the Heritage Museum of Orange County near Centennial Park. Some have surmised that the “Gospel Swamp” name stretched as far west as parts of Fountain Valley, although details about that particular boundary are hazy.

From the top of Upper Newport Bay to the foothills above Tustin and Irvine, the wetlands were almost impassable during the rainy season. When California was under Spanish and Mexican rule, the place was called la Cienega de las Ranas – the Swamp of the Frogs. Millions of tiny frogs could be heard “singing” for miles around each night, making it a landmark for travelers on El Camino Real. Today’s San Joaquin Marsh was part of the cienega.

The Bolsa Chica wetlands in Huntington Beach are named for the Mexican rancho they were once part of. It’s still an amazing repository of wildlife and is a critical spot for many species of birds during their migration up and down the coast. But it also has a rich human history. One can still find evidence of its Indian village sites, the exclusive Bolsa Chica Gun Club, the oil boom, the (now missing) Freeman River, World War II shore defenses and the modern battle between environmentalists and developers.

For much of our history, the soggy parts of Orange County were both an annoyance and a boon. While it made the land useless for some purposes, the soil was rich with nutrients and damp enough to create booming industries in sugar beets, celery, lima beans, and other crops that benefit from constant moisture. The wetlands also served as a home for dozens of gun clubs or duck clubs, making Orange County a hunter’s paradise from Bolsa Chica to San Joaquin Marsh.

Today, we recognize the value of wetlands and the many ways they provide a healthier environment for plants, animals and people. Instead of draining and paving them, there are efforts to preserve and even restore the marshlands that survive. 

Swamps: More proof that Orange County is more than Disneyland, and that all our local ducks don’t all wear sailor suits or hockey masks.
