Dimmit County, in southern Texas, is bordered by Zavala, La Salle, Webb, and Maverick counties. Carrizo Springs, the county's largest town and the county seat, is located in the northwestern part of the county at the intersection of U.S. Highways 83 and 277. The center point of the county is 28°25' north latitude and 99°46' west longitude. Dimmit County was named for Philip Dimmitt, one of the framers of the Goliad Declaration of Independence; his name was misspelled when the county was formed. The county comprises 1,307 square miles of generally flat to rolling terrain vegetated with mesquite and small trees, scrub brush, cacti, and grasses. The elevation of the county ranges from approximately 500 to 800 feet. Soils in the nearly level areas are loamy and sometimes poorly drained, while soils in the rolling south central part of the county are loamy to clayey. Most of Dimmit County is drained by the Nueces River, which flows across the northeastern quarter. In 1982 almost 90 percent of the county's land was devoted to ranching and farming. Two percent of the land was cultivated, largely with irrigation. Dimmit County is known as part of the Winter Garden Region for the vegetables grown there. Mineral resources include caliche, industrial sand, sand and gravel, oil, gas, and lignite coal. Oil and gas production is significant. Temperatures in Dimmit County range from an average high of 99° F in July to an average low of 40° in January, with average annual temperature of 72°. Rainfall averages twenty-two inches a year, and the growing season lasts for 290 days.
