Sour Lake is a city in Hardin County, Texas, United States. The population was 1,773 at the 2020 census.[4] It was originally named "Sour Lake Springs", after the sulphurous spring water that flowed into the nearby lake.[5] The city is part of the Beaumont - Port Arthur Metropolitan Statistical Area. Sour Lake is the oldest surviving town in Hardin County.[5] It is called by some the "Gateway to the Big Thicket".
Sour Lake was first settled around 1835 when the Mexican state of Coahuila y Tejas granted Stephen Jackson one league of land covering 4428acres by land grant.[5] Sam Houston visited Sour Lake in his later years.[5] The town is home to one of the biggest sinkholes in Texas.
Sour Lake became a short-lived boomtown with the discovery of oil in 1901, shortly after oil was found at the nearby Spindletop salt dome.[5] It is known as the birthplace of Texaco.[5] Formed in 1903, the Texas Company (Texaco's former corporate name) is one of the three major oil companies that can trace its origins to the oil fields around Southeast Texas. The Sour Lake oilfield produced about of oil up to 1948, when it was producing about daily and new drilling was still underway.[5] Today the Sour Lake oilfield is the oldest continuously producing oil field in the world.
The town of Atcheson in Bruce McCandless's 2012 novel Sour Lake appears to be based at least loosely on the real Sour Lake. Atcheson, like the real-life Sour Lake, is situated in the Big Thicket and experienced a short-lived oil boom in early years of the 20th century. Yvette Benavides, in a San Antonio Express-News review of the book, noted, "There is a lot that is historically factual in this novel. That's part of the fun of reading Sour Lake."[6]
The Ecuadorian jungle town commonly referred to as Lago Agrio was named after Sour Lake by Texaco when the company established the oil-producing settlement. Lago Agrio is Spanish for "Sour Lake". The official name of the Ecuadorian town is Nueva Loja.
