Lake County is a county located in the north central portion of the U.S. state of California, north of the San Francisco Bay Area. It takes its name from Clear Lake, the dominant geographic feature in the county. As of 2000 the population was 58,309. The county seat is Lakeport. The central geographical feature of Lake County being Clear Lake, the largest natural lake wholly within California (unlike Lake Tahoe which is partially in Nevada). Lake County is colloquially referred to as "The LC" or "The County" by some local residents.


Lake County was formed in 1861 from parts of Napa and Mendocino counties. Lake County has long been known as a farming community. Vineyards were planted in the 1870s; by the early 1900’s the area was earning a reputation for producing some of the world's greatest wines. However, in 1920 Prohibition forced an end to Lake County wine production. Most of the vineyards were ripped out and replanted with walnut and pear farms. Re-emergence of the wine industry began in the 1960s when a few growers rediscovered the area's grape growing potential and began planting vineyards. The area went from less than 100 acres (0.4 km2) of grapevines in 1965 to over 8,800 acres (36 km2) of vineyards today, and has seen the recent establishment of several American Viticultural Areas such as High Valley and Red Hills. Many of the vineyards in Lake County today support sustainable farming practices.

Geography and environment[]

According to the U.S. Census Bureau, the county has a total area of 3,443 km² (1,329 sq mi). 3,258 km² (1,258 sq mi) of it is land and 185 km² (72 sq mi) of it (5.38%) is water. A number of watercourses drain the county including Cache Creek, Forbes Creek and Scotts Creek.

Clear Lake is believed to be the oldest 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 Mount Konocti. 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 and the tule elk. Waterfowl, fish and other wildlife abound in the Clear Lake basin.

The recent sharp increase in per capita income can be directly linked to those people who have recently relocated to Lake County and telecommute to their jobs in the Bay Area. In addition, real estate values have risen due to a boom from 2003 to 2006, caused by Bay Area residents' discovery that Lake County residential real estate was lower in cost than that in adjacent Napa, Sonoma and Mendocino counties.

Within Lake County are two incorporated cities, the county seat of Lakeport and Clearlake, the largest city, and the communities of Kelseyville, Blue Lakes, Clearlake Oaks, Clearlake Park, Cobb, Finley, Glenhaven, Hidden Valley Lake, Clearlake Riviera, Loch Lomond, Lower Lake, Lucerne, Middletown, Nice, Spring Valley, Upper Lake, Whispering Pines, and Witter Springs.

The income of residents of the county varies widely. The county is the largest employer thus far, followed by large retailers such as Wal-Mart, Safeway, and Kmart. Several franchised retailers have recently entered the county (up 28% since 2003) and have created a diverse employment environment. Many wealthy people and retirees maintain residences near the lake, with the Clearlake Riviera's, Buckingham and Paradise Cove having the largest concentration. Employment statistics continue to improve, again supported by the influx of Bay Area relocations and the benefit of telecommuting. Lake County is mostly agricultural, with tourist facilities and some light industry. Major crops include pears, walnuts and, increasingly, wine grapes.
