Lake County forms the Clearlake, California micropolitan statistical area.[8] It is directly north of the San Francisco Bay Area.

Lake County is part of California's Wine Country, which also includes Napa, Sonoma, and Mendocino counties. It includes nine American Viticultural Areas[9] and around 20 bonded wineries.

History

Lake County has been inhabited by Pomo Native Americans for over ten thousand years. Pomos had been fishermen and hunters, known especially for their intricate basketry made from lakeshore tules and other native plants and feathers. Pomo people continue to live in Lake County.[10]

The area had European American settlers since at least the 1840s. Lake County was created in 1861 from parts of Napa and Mendocino counties.[11] The eastern boundary of Lake County, which was not clearly specified in the 1861 act, was clarified by legislative acts passed in 1864 and 1868.[12] A major effect of the 1868 act was to include in Lake County the entire watershed of North Fork Cache Creek, which had previously been claimed by Colusa County.[13]

The 1911 California Blue Book lists the major crops as Bartlett pears and beans. Other crops include grain, alfalfa, hay, prunes, peaches, apples, grapes and walnuts. Stockraising included goats, hogs, turkeys and dairying.[14]

Some vineyards were planted in the 1870s by European Americans, but the first in the state were established in the 18th century by Spanish missionaries. By the early 20th century, the area was earning a reputation for producing some of the world's greatest wines. However, in 1920, national prohibition essentially ended Lake County's wine production. With authorized cultivation limited to sacramental purposes, most of the vineyards were ripped out and replanted with walnut and pear orchards.

Geography

According to the U.S. Census Bureau, the county has a total area of 1,329 square miles (3,440 km2), of which 1,256 square miles (3,250 km2) is land and 73 square miles (190 km2), or 5.5%, is water.[15] Two main watercourses drain the county: Cache Creek, which is the outlet of Clear Lake; and Putah Creek. Both of these flow to the Sacramento River. The main streams which flow into Clear Lake are Forbes Creek, Scotts Creek, Middle Creek, and Kelsey Creek. At the extreme north of the county Lake Pillsbury and the Van Arsdale Reservoir dam the Eel River, providing water and power to Ukiah in Mendocino County.

Clear Lake is believed to be the oldest warmwater lake in North America, due to a geological fluke. The lake sits on a huge block of stone which slowly tilts in the northern direction at the same rate as the lake fills in with sediment, thus keeping the water at roughly the same depth. The geology of the county is chaotic, being based on Franciscan Assemblage hills. Numerous small faults are present in the south end of the lake as well as many old volcanoes, the largest being Cobb Mountain. The geologic history of the county shows events of great violence, such as the eruption of Mount Konocti and Mount St. Helena and the collapse of Cow Mountain, which created the hills around the county seat of Lakeport. Blue Lakes, Lake Pillsbury, and Indian Valley Reservoir are the county's other major bodies of water.

Lake County has habitats for a variety of species of concern including the uncommon herb, Legenere limosa, the rare Eryngium constancei, and the tule elk. Waterfowl, bear, and other wildlife abound in the Clear Lake basin.

Due to its surrounding hilly terrain, Lake County is the only one of California's 58 counties never to have been served by a railroad line.

Mineral springs

In the late 19th century, the worldwide popularity of mineral water for the relief of myriad physical ailments resulted in the development of mineral resorts around Clear Lake.[16]

  • Greene Bartlett discovered Bartlett hot springs in 1870. The springs were developed into a resort and by 1900 included a mineral water bottling plant. The resort burned down in 1934.[17]
  • Harbin Hot Springs was developed by settlers in the 1860s and burned to the ground in the Valley Fire of 2015. The resort partially reopened in January 2019, including the main pools and sauna, and a limited cafeteria service.[18]
  • Highland Springs opened in 1891 and was destroyed by fire in 1945. During its time, Highland had an elegant dining room and a spacious hotel.[16]
  • Saratoga Springs Resort was opened by J. J. Liebert in 1873 with several cabins, and within two decades had room for 350 guests.[19]
  • Witter Springs Resort opened in 1873 with a hotel and guest cottages.[19]

Climate

Lake County has a Mediterranean climate with hot summer daytime temperatures in its lower elevations. Nighttime temperatures remain cool year-round, somewhat moderating average temperatures and relieving the summer heat.

Politics

Overview

In its early history, Lake County leaned Democratic in Presidential and congressional elections. It supported every Democratic presidential candidate between 1864 and 1916 except Alton B. Parker in his 1904 landslide defeat.[43] Nonetheless, between 1920 and 1984 Lake County tended towards leaning Republican and was won by just four Democratic nominees – Franklin D. Roosevelt in 1932 and 1936, Lyndon B. Johnson in 1964 and Jimmy Carter in 1976. Ronald Reagan in 1984 won a majority in the county, which later reverted to leaning Democratic.[43] In 2016, Republicans broke 40% of the vote for the first time since 2004, and Democrats failed to win 50% of the vote for the first time since 1996. Democrats broke 50% again in 2020, increasing their margin of victory, although Republicans still increased their percentage of the vote.[44] In 2022, the county was won by Republicans in several statewide races.[45] In 2024, Donald Trump won Lake County by 367 votes, marking the first time since Reagan's 1984 run that a Republican candidate won the presidential race in Lake County.[46]

On November 4, 2008, Lake County voted 52.6% for Proposition 8, which amended the California Constitution to ban same-sex marriages.[47] In November 2024, Proposition 3, titled Constitutional Right to Marry, which effectively repealed Proposition 8, received 57.04% of "Yes" votes in the county.[46] In 2025, the county narrowly rejected Proposition 50 by a 50.1% to 49.9% margin.

Wine Country

Lake County vineyards

The first vineyards in Lake County were planted in the late 19th century, but Prohibition and the county's remoteness dealt a blow to the area's viticulture. A reemergence of the wine industry began in the 1970s, although most of the region's grapes are still trucked to neighboring Napa, Sonoma and Mendocino counties for vinification. The county saw its vineyard acreage increase from fewer than 100 acres (40 ha) in 1965 to more than 11,000 acres (4,500 ha) in 2023[62]

The region is host to nine American Viticultural Areas, notably Guenoc Valley, High Valley and the Red Hills, and about 20 winery operations.

Transportation

Major highways

There are also several numbered county routes in Lake County.

Public transportation

Lake Transit serves all areas around Clear Lake. Local routes serve Lakeport, Clearlake and Lower Lake. Connections are also provided to St. Helena (in Napa County) and Ukiah (in Mendocino County). Some routes operate on weekdays only; no service is provided on Sundays and observed public holidays.[63][64]

Airports

Lampson Field (IATA: CKE, ICAO: LID, FAA LID: 1O2) is the county's public airport. A 4,000 foot (1,200 m) airstrip is located in Gravelly Valley, north of Lake Pillsbury.[65] There are also several private airstrips located throughout the county. The county was once host to the Paul Hoberg Airport in the Cobb area, which by the early 1980s was considered abandoned.[66]

Historical railroads

In 1888 the Vaca Valley and Clear Lake Railroad reached Rumsey, but the planned line to Clear Lake was never built. The Clear Lake Railroad started work on a line from Hopland to Lakeport: "In November 1911 first ground was broken for the Hopland-Clear Lake railroad to Hopland. Mrs Harriet Lee Hammond, wife of the president of the road started construction. ... There were six miles of track out of Hopland ...", but this was also abandoned.[67][68][69]

Culture

The Lake County Arts Council is the official arts council for Lake County, California, founded in 1981.[70] It runs under the California Arts Council (CAC). The Lake County Arts Council runs the Main Street Gallery, a small gallery for visual arts with space for arts classes in Lakeport, Ca. This space is also used for the Lake County Arts Council's literary program, which hosts the county's Poetry Out Loud Program, recurring Writer's Circles, and more. In addition, the Lake County Arts Council has other events and programs including Art in Public Places, the Spring Dance Festival, and the Summer Youth Art Camp.[citation needed] The Lake County Arts Council also owns and operates the Soper Reese Theatre,[71] Lake County's only fixed seating theatre located in Lakeport, California. The Soper Reese Theatre is a live performance venue that shows live theatrical shows, dance, live music, and has a Classic Cinema showing twice a month.
