Steeped in history. Sour Lake began as a health resort in the 1840s complete with a grand hotel and bath houses. Sam Houston came several times to Sour Lake springs seeking relief from his war wounds. His last trip was in June, 1863. He later died at his home in Huntsville on July 26, 1863. The discovery of oil in 1902 would soon doom the grand hotels and mineral baths. The TTC Fee No. 3 on January8, 1903 would be the start of the world oil giant Texaco. The Sour Lake oilfield produced about 90,000,000 barrels of oil up to 1948, when it was producing about 3,500 barrels daily and new drilling was still underway. Today the springs are gone but oil remains.
