Piru Creek is a large stream in northern Los Angeles County and eastern Ventura County, California. It is a tributary of the Santa Clara River, the largest stream system in Southern California that is still relatively natural. It drains an area of about 497 square miles (1,290 km2) and is about 71 miles (114 km) long.[3] The creek is the Santa Clara's largest tributary, providing about one-half of its flow. There are two major reservoirs on Piru Creek, which provide storage for irrigation and water from the California Aqueduct.

Course

Piru Creek originates as several small springs on the north side of Pine Mountain Ridge (California) of the Santa Ynez Mountains, in the Los Padres National Forest. It flows eastwards through a valley, then south to the confluence with Cedar Creek from the right. After the Cedar Creek confluence the stream turns northeast, receives Sheep Creek from the left, and Mutau Creek on the right. Piru Creek receives Lockwood Creek from the left at Sunset campground on Lockwood Flat, and flows east into a canyon where the valley walls pull in and rise steeper and higher above the river.[4][5]

The Smith Fork of Piru Creek comes in from the left where the main stem turns sharply southeast, then widens into the Topatopa Mountains, soon forming the boundary between Mount Pinos and Saugus Ranger Districts of the National Forest and dropping over Piru Creek Falls near the remains of California State Route 99.[4][5]

The creek flows south through Piru Gorge until Frenchman's Flat and the adjoining Osito Creek confluence, which sends the Piru sharply hurrying to the west, then south again where it receives Fish Creek from the right. It crosses the boundary between Los Angeles County and Ventura County five times before being impounded in Lake Piru, the second reservoir on the creek, formed by Santa Felicia Dam.

Downstream of the dam the creek's valley broadens and the creek is allowed to form meanders. It finally exits from its canyon between a pair of ridges just east of the town of Piru. Its confluence with the Santa Clara River, here a wide gravelly wash, occurs soon after.[4][5]

History

Thousands of years ago, Native Americans of the Chumash group lived in the area, but by 500 CE, their former territory along Piru Creek had been occupied by the Tataviam. It is believed that there were once up to 25 Native American villages on the river, of which eight have been thoroughly studied. Spanish explorer Don Gaspar first traveled up the creek in 1769.[6] In 1839, the government of Mexico which then held control over Alta California granted the 48,612-acre (19,673 ha) Rancho San Francisco to Antonio del Valle.[7] The Rancho Camulos was created out of Rancho San Francisco land by Ygnacio del Valle in 1853, and included much of the Santa Clara River and Piru Creek Valleys.[8]

In 1842, traces of gold were found on a tributary of the Santa Clara River, Placerita Creek, which joins the main stem about 10 miles (16 km) upstream of Piru.[7] Bn the late 19th century, prospectors discovered traces of calcite on Piru Creek in Lockwood Valley near Frazier Mountain, north of present-day Pyramid Lake. A town called Lexington was platted near the site in 1887 but never actually materialized. Ironically, the real mineral of value in the region turned out to be borax, which was mined in the 1880s by the Frazier Borate Company.[9]

The company town, Stauffer, was established on the Piru in time, and by 1905 had grown to such a size that a post office was set up in the town, which finally was abandoned in 1942 because of dwindling profits from borax mining.[9] The Russell Borate Mining Company also acquired land in the region in 1907 between a pair of earlier excavations. By 1912, the Russell mine was the only one left in operation. Ultimately, all the mines were abandoned because of competitions from borax operations in Death Valley.[10]

Below Pyramid Dam, a cement culvert adjoining the remains of Highway 99 creates a 15-foot (4.6 m) waterfall. This is the uppermost limit of natural fish spawning on the creek below Pyramid Dam.

Piru Creek was once a hot spot for both fly fishing and bait-casting anglers as it contained both wild and hatchery-raised rainbow trout along with largemouth bass. The creek is no longer stocked with trout by the California Department of Fish and Game [19] and, due to lack of enforcement from the California Department of Fish and Game,[20] frequent poaching of fish from the creek has reduced both the trout and bass population.[21]

At one time fishing on Piru Creek was a year-round activity. Certain spots, posted as “catch and release” areas and restricted to fishing with barbless, artificial lures, are still somewhat active along a three-mile stretch of the creek from Pyramid Dam to Frenchman’s Flat with the best conditions for fishing from January to April (limit of 5 fish per angler). The 900-foot (270 m) reach from Pyramid Dam to a small bridge downstream is closed to any fishing.

In the spring, the stretches of Piru Creek from Pyramid Lake to Lake Piru and from Santa Felicia Dam to the mouth are actually possible to raft and kayak. The 15-mile (24 km) first stretch has rapids up to Class IV and includes the challenging section known as Falls Gorge,[15] while the calmer 4-mile (6.4 km) second reach has Class I-II rapids only.[16] Controlled water releases from the two dams provide some regulation of the flow although an effort is made to simulate natural discharges. As a result, the section is usually only runnable after rainfall.[17] From 0.5 miles (0.80 km) downstream of Pyramid Dam to the Los Angeles-Ventura County line, Piru Creek in various sections is designated a National Wild and Scenic River.[18]

[14][13] The entire hike can require more than two days to complete, and flooding from Piru Creek is a potential danger.[12] and it is possible to continue all the way south from there to Lake Piru with much scrambling and wading.[11]
