Owens Lake (Arkansas)

Owens Lake is a mostly dry lake in the Owens Valley on the eastern side of the Sierra Nevada in Inyo County, California. It is about south of Lone Pine. Unlike most dry lakes in the Basin and Range Province that have been dry for thousands of years, Owens held significant water until 1913, when much of the Owens River was diverted into the Los Angeles Aqueduct, causing Owens Lake to desiccate by 1926. In 2006, 5% of the water flow was restored. As of 2013, it is the largest single source of dust pollution in the United States.

History

Owens Lake was given its present name by the explorer John C. Frémont, in honor of one of his guides, Richard Owens. The lake is called ''Patsiata'' by the Mono people.

Before the diversion of the Owens River, Owens Lake was up to long and wide, covering an area of up to . In the last few hundred years the lake had an average depth of , and sometimes overflowed to the south, after which the water would flow into the Mojave Desert.
In 1905, the lake's water was thought to be "excessively saline."
It is thought that in the late Pleistocene about 11–12,000 years ago Owens Lake was even larger, covering nearly and reaching a depth of . The increased inflow from the Owens River, from melting glaciers of the post-Ice Age Sierra Nevada, caused Owens Lake to overflow south through Rose Valley into another now-dry lake bed China Lake, in the Indian Wells Valley near Ridgecrest. On November 5, 1913, William Mulholland finished the Los Angeles aqueduct. Water was piped and canalized from Owens River to the Van Norman Reservoir.

Starting in 1913, the river and streams that fed Owens Lake were diverted by Los Angeles Department of Water and Power (LADWP) into the Los Angeles Aqueduct, and the lake level started to drop quickly. As the lake dried, soda processing at nearby Keeler, California, switched from relatively cheap chemical methods to more expensive physical ones. The Natural Soda Products Company sued the city of Los Angeles and built a new plant with a $15,000 settlement. A fire destroyed this plant shortly after it was built, but the company rebuilt it on the dry lake bed in the 1920s.

During the unusually wet winter of 1937, LADWP diverted water from the aqueduct into the lake bed, flooding the soda plant. Because of this, the courts ordered the city to pay $154,000. After an unsuccessful appeal to the state supreme court in 1941, LADWP built the Long Valley Dam, which impounded Lake Crowley for flood control.

A 2004 court order required the LADWP to reestablish a small flow from the river into the lake. In winter 2006, the Los Angeles Department of Water and Power restored 5% of the pre-aqueduct flow to the river by court order, allowing the Owens River Gorge, the river bed in the valley, and Owens Lake to contain a small amount of water. The lake was the epicenter of a magnitude 5.8 earthquake that occurred on June 24, 2020.

In 2022, Great Basin Unified Air Pollution Control District successfully sued LADWP for failure to control pollution at Owens lake on sensitive Native American cultural resources land

In 2023, the lake flooded for the first time in over 100 years due to the numerous storms that struck California during the first three months of 2023.

Conditions

The lake is a large salt flat whose surface is made of a mixture of clay, sand, and a variety of minerals including halite, burkeite, mirabilite, thenardite, and trona. In wet years, these minerals form a chemical soup in the form of a small brine pond within the dry lake. When conditions are right, bright pink halophilic (salt-loving) archaea spread across the salty lake bed. Also, on especially hot summer days when ground temperatures exceed 150° F (66 °C), water is driven out of the hydrates on the lake bed creating a muddy brine. More commonly, periodic winds stir up noxious alkali dust storms that carry away as much as four million tons (3.6 million metric tons) of dust from the lake bed each year, causing respiratory problems in nearby residents. The dust includes carcinogens, such as cadmium, nickel and arsenic.

Management

The LADWP and the California State Lands Commission own most of the Owens Lake bed, though a few small parcels along the historic western shoreline are privately owned. In 2004, the California Department of Fish and Wildlife (CDFW) acquired a parcel at the foot of Owens Lake. Designated the Cartago Wildlife Area in 2007, it is one of the few remaining spring and wetland areas on the shore of Owens Lake. CDFW is using mitigation funds from CalTrans to enhance habitat.

As part of an air quality mitigation settlement, LADWP is shallow flooding of the salt pan to try to help minimize alkali dust storms and further adverse health effects. There are also about of managed vegetation being used as a dust control measure. The vegetation consists of saltgrass, which is a native perennial grass highly tolerant of the salt and boron levels in the lake sediments. Gravel covers are also used.

Ecology

This once-blue saline lake was an important feeding and resting stop for millions of waterfowl each year. During a visit to Owens Lake in 1917 Joseph Grinnell from the Museum of Vertebrate Zoology in Berkeley reported "Great numbers of water birds are in sight along the lake shore--avocets, phalaropes, ducks. Large flocks of shorebirds in flight over the water in the distance, wheeling about show in mass, now silvery now dark, against the gray-blue of the water. There must be literally thousands of birds within sight of this one spot".

Owens Lake is recognized as an Important Bird Area in California by the National Audubon Society. At the shore, a chain of wetlands, fed by springs and artesian wells, keep part of the former Owens Lake ecosystem alive. Snowy plovers nest at Owens along with several thousand snow geese and ducks. As a result of dust mitigation efforts, shallow flooding of the lake bed has created both shallow and deeper (about deep) habitats on the lake bed.Sahagun, Louis (November 14, 2014
"New dust-busting method ends L.A.'s longtime feud with Owens Valley"
''Los Angeles Times'' This water, although seasonally applied, is helping to buoy the lake's ecosystem causing hope in conservationists that an expanded shallow flooding program could do even more. There are no plans to restore Owens to anything resembling a conventional lake.

On April 19, 2008, the Eastern Sierra Audubon Society, Audubon California, and the Owens Valley Committee held the first lake-wide survey of the bird populations of Owens Lake. Volunteers recorded a total of 112 avian species and 45,650 individual birds — the highest total number of birds ever officially recorded at Owens Lake. Volunteers identified 15 species of waterfowl (ducks and geese) and 22 species of shorebirds. The highest totals for individuals of a species included 13,873 California gulls (an inland nester at Mono Lake and elsewhere); 9,218 American avocets; 1,767 eared grebes; 13,826 ''peeps'' or small sandpipers such as dunlin, western and least sandpipers; and 2,882 individual ducks.

Local industry

Cerro Gordo Mines

The town of Cartago, below the Sierra Nevada near present-day Olancha, California, was the western shipping port for the Cerro Gordo Mines production and transported goods across Owens Lake with the northern ports of Swansea and Keeler directly below the mines. From Cartago a barge-like vessel, the ''Bessie Brady,'' was launched in 1872, which cut the three-day freight journey around the lake down to three hours.

Much of the freight it carried was silver and lead bullion from the Cerro Gordo mines, which at their height were so productive that the bars of the refined metals waited in large stacks before twenty-mule team teamsters could haul it to Los Angeles. The trying three-week (one way) journey improved after the formation of the Cerro Gordo Freighting Company, run by ancestors of regional historian Remi Nadeau who has written of this period.

The town of Keeler, below the Inyo Mountains on the former north shore, replaced Swansea as the shipping port for the mines after the 1872 Lone Pine earthquake. In the 1870s it had a population of 5,000 people as the center of trade for the Cerro Gordo mines.

The Cottonwood Charcoal Kilns, traditional stone masonry 'beehive' charcoal kilns, were built to transform wood from trees in Cottonwood Canyon above the lake into charcoal, to feed the Cerro Gordo mines' silver and lead smelters across the lake at Swansea. The ruins are located on the southern side of the lake bed near Cartago. They were similar to the nearby Panamint Charcoal Kilns near Death Valley. The kilns are identified as California Historical Landmark #537.

Other enterprises

In 1879 silver mining ended, but Keeler was saved when the Carson and Colorado Railroad built narrow-gauge rail tracks to the town. It then became a soda, salt, and marble shipping center until 1960. The rail line had been sold to Southern Pacific Railroad in 1900. Keeler's current population is around 50 people and continues in decline.

In the 20th century the Clark Chemical Company operated on the northwestern shore at Bartlett, with evaporation ponds for lake brine and a plant to extract its chemicals.

Mineral extraction plants around the lake:

* Inyo Development Company, 1887–1920
* Natural Soda Products Company/Michigan Alkali Company/Wyandotte Chemical Corporation, 1912–1953
* California Alkali Company/Inyo Chemical Company, 1917–1932
* Pacific Alkali/Columbia-Southern Chemical Corp./ Pittsburgh Plate Glass, 1928–1968
* Permanente Metals Corporation, 1947–1950
* Morrison and Weatherly Chemical Corporation (M&W)/Lake Minerals Corporation (LMC)/Cominco American Inc./Owens Lake Soda Ash Company (OLSAC)/U.S. Borax/Rio Tinto Minerals, 1962–present. Rio Tinto Minerals has mineral lease renewals through 2048.

In popular culture

Numerous Western films have been shot by Owens Lake, including '' Westward Ho'' (1935), ''Maverick'' (1994), '' Riders of the Dawn'' (1937), '' Across the Plains'' (1939), '' Stage to Tucson'' (1951), '' From Hell to Texas'' (1958) and '' Nevada Smith'' (1966).

Other films that had scenes shot at Owens Lake or the nearby Alabama Hills where Owens Lake is visible includes ''Top Gun'' (1986), and '' Tremors'' (1990).Lone Pine Film History Museum, http://www.lonepinefilmhistorymuseum.org/film-history

Public access

The Cartago Wildlife Area continues to develop as a wildlife-viewing area for the public. The site is open year-round for viewing numerous bird species attracted to the ponds and wetlands as well as the ruins of a historic soda ash plant from the World War I era and the 1920s.
