Madison County

Madison County is located in central East Texas. Madisonville, the county seat and largest town, is near interstate Highway 45 about 100 miles northwest of Houston; the town is at 30°57' north latitude and 95°55' west longitude, close to the center of the county. Madison County includes 473 square miles primarily of post oak savannah, a mixture of post oak woods and grasslands. The northeast and south central parts of the county are in the Blackland Prairies region; the southeast corner of the county lies in the Piney Woods. Today, about one-fifth of the area is timbered, but early reports describe it as two-thirds timber and one-third prairie. It supported oak, cedar, elm, walnut, hickory, gum, pecan, ash, cypress, and pine. The terrain is undulating, with an elevation ranging from 213 to 364 feet above sea level. The rolling prairies drain to the waterways that form the county's boundaries: the Trinity River in the east, the Navasota River in the west, and Bedias Creek in the south. Numerous other creeks run through the county, notably the Caney, which bisects it. Several soil types are found in the county, which lies principally in the Claypan area. They range from black waxy to light sandy loam around creeks and lower lands, with dark chocolate mixed with sand on the prairie uplands. Almost the entire county is made up of soils with sandy surface layers and mottled yellow, red, and gray loamy subsoils. The northwest portion is surfaced by noncalcareous and calcareous cracking clayey soils and slightly acid soils with loamy surface layers and cracking clayey subsoils. Oil and gas are found in the county, as are lignite, sand, and gravel. Madison County has a mild climate, with an average growing season of 272 days. Its average annual rainfall is 41.50 inches, and temperatures range from a January minimum average of 40° F to a July maximum average of 94°.
