Kings County sits near the heart of California’s southern San Joaquin Valley, but its history reaches far beyond the county lines drawn in the late nineteenth century. Long before Hanford became the county seat or railroads crossed the valley floor, the region was shaped by rivers, wetlands, Indigenous communities, seasonal flooding, and the immense body of water now commonly known as Tulare Lake.
Understanding Kings County California history means looking at how land, water, transportation, agriculture, industry, and generations of people transformed the region. It is a story that begins with Pa’ashi and continues through railroad expansion, county formation, agricultural development, oil discoveries, military aviation, and modern debates about groundwater and the future of the Tulare Lake Basin.
Pa’ashi and the Landscape Before Kings County
Before Kings County existed, much of the surrounding landscape looked dramatically different from the agricultural valley seen today. Tulare Lake occupied the lowest portion of the basin and expanded or contracted depending on rainfall and snowmelt flowing from the Sierra Nevada.
The lake was fed by several rivers, including the Kings, Kaweah, Tule, and Kern. Wetlands, tule marshes, sloughs, and riparian areas surrounded the water and created an environment rich in fish, birds, plants, and other wildlife.
The Tachi Yokuts and other Yokuts communities lived in the Tulare Lake Basin for generations. The Tachi name Pa’ashi, often translated as “big water,” reflects the importance of the lake within the Indigenous landscape. Archaeological and historical research continues to demonstrate that the basin was not an empty wilderness waiting for settlement, but a populated cultural landscape with long-established communities and traditions.
Modern research is bringing renewed attention to this history. The Pa’ashi Archaeological Collaboration, involving UCLA researchers and representatives of the Tachi Yokuts Tribe, is examining archaeological, environmental, and community knowledge to build a more complete understanding of Tulare Lake and its history.
Water Defined the Early Landscape
The Kings River was another defining feature. Water moving west from the Sierra Nevada helped support wetlands, wildlife, settlements, and later agriculture. The river eventually gave Kings County its name and remains inseparable from the county’s environmental and economic history.
A Landscape That Changed With the Seasons
Tulare Lake did not maintain one permanent shoreline. Its size changed greatly between dry and wet periods. In extremely wet years, water spread across vast sections of the valley floor. During drier periods, the shoreline retreated and exposed fertile land.
This natural cycle became increasingly controlled by human engineering during the nineteenth and twentieth centuries.
Settlement, Water Diversion, and Agricultural Expansion
California’s population changed rapidly after the mid-nineteenth century. Settlers moved into the San Joaquin Valley, established farms and ranches, and began diverting water from rivers and sloughs.
Canals, irrigation systems, levees, and later large dams dramatically changed how water moved through the Tulare Basin. According to the U.S. Geological Survey, rivers that historically flowed toward Tulare Lake were increasingly diverted for agricultural use.
As water was redirected, former wetlands and lakebed areas became valuable farmland. Agriculture eventually became one of the defining features of Kings County.
The Arrival of the Railroad
Transportation accelerated settlement. The Southern Pacific Railroad reached the area in 1877, helping connect local agricultural communities with larger California markets.
Rail transportation encouraged the growth of towns, warehouses, businesses, and shipping facilities. Hanford and Lemoore were among the communities whose development became closely connected to railroad access and agricultural commerce.
How Kings County Was Created in 1893
Kings County was formally established in 1893 when voters approved the creation of a new county from a portion of Tulare County. Hanford became the county seat.
The new county brought together agricultural communities, developing towns, transportation routes, and landscapes associated with the Kings River and Tulare Lake Basin. Additional territory from Fresno County was added to Kings County in 1909.
The County of Kings identifies early settlers, agriculture, the railroad, and the county’s 1893 formation as major elements of its historical development.
Hanford Becomes a Regional Center
Hanford grew into the county’s principal civic and commercial center. Businesses, government offices, transportation connections, cultural institutions, and residential neighborhoods expanded as the surrounding agricultural economy developed.
Lemoore, Corcoran, Armona, Stratford, Kettleman City, and other communities developed their own identities, often closely connected to farming, transportation, water, or later industrial activity.
Conflict and Change in an Agricultural Region
The transformation of the valley was not always peaceful. One of the region’s best-known historical episodes was the 1880 Mussel Slough conflict, which grew from disputes involving settlers, railroad land ownership, and land prices.
The confrontation became part of the broader history of railroad expansion in California and reflected tensions that often accompanied the transfer of land and the rapid economic development of the American West.
Farming Reshapes Kings County
Over the following decades, irrigation helped make large-scale agriculture possible across much of Kings County. Farms produced field crops, fruit, livestock, dairy products, and other commodities.
The same water systems that supported agriculture also reshaped the historic Tulare Lake Basin. By the end of the nineteenth century, extensive diversion had caused the lake to largely disappear during ordinary years, although major floods periodically returned water to the old lakebed.
Oil, Aviation, and a Changing Economy
Agriculture was not Kings County’s only major industry. Oil development in the Kettleman Hills became significant after major discoveries during the late 1920s. The resulting activity contributed to the growth of Avenal and brought another economic chapter to western Kings County.
Military aviation also became increasingly important during the twentieth century. Aviation facilities developed during World War II, and Naval Air Station Lemoore later became a major presence in the western part of the county.
These developments added new layers to a region already shaped by agriculture, rail transportation, water systems, and small-town growth.
Tulare Lake Returns to Public Attention
The old lakebed has never entirely lost its connection to water. During exceptionally wet periods, floodwater has repeatedly returned to portions of the basin. The dramatic reappearance of Tulare Lake in 2023 renewed widespread interest in the region’s environmental history.
The event reminded Californians that modern farms and water-control systems exist on top of a landscape formed by rivers, wetlands, and recurring floods.
Why Water History Still Matters in 2026
Water remains one of the most important issues facing Kings County. The Tulare Lake Subbasin continues to receive attention under California’s Sustainable Groundwater Management Act. The California State Water Resources Control Board provides current information concerning groundwater management in the Tulare Lake Subbasin.
These modern issues show why local history is more than a record of the past. Historical decisions about canals, dams, irrigation, farming, groundwater, and land use continue to influence communities today.
Preserving the History of Kings County
Kings County’s history can be found in far more than official documents. It survives in historic buildings, family photographs, agricultural equipment, railroad routes, maps, oral histories, waterways, old neighborhoods, and the stories preserved by local communities.
It is also important to recognize that different groups experienced the county’s development in different ways. Indigenous communities, farmers, migrant workers, railroad employees, business owners, military families, and generations of residents all contributed to the region’s history.
A Story That Continues to Develop
Research into Kings County is still evolving. Archaeology, tribal knowledge, archival discoveries, environmental science, historical photographs, and public records continue to add detail to our understanding of the region.
By looking closely at Pa’ashi, the Kings River, agriculture, transportation, industry, and community life, we can better understand how Kings County became what it is today.
