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 lakebed in the 1920s. During the unusually wet winter of 1937, LADWP diverted water from the aqueduct into the lakebed, 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. 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 Conditions The lake is currently 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 lakebed. Also, on especially hot summer days when ground temperatures exceed 150° F (66 °C), water is driven out of the hydrates on the lakebed 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 lakebed 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 currently shallow flooding of the salt pan to try to help minimize alkali dust storms and further adverse health effects.
