Armand Bayou

Type: General Entry

Published: November 1, 1994

Armand Bayou, also known as Middle Bayou, rises in central Pasadena twenty miles south of Houston in southeastern Harris County (at 29°40' N, 95°09' W) and runs ten miles southeast along the eastern edge of the Clear Lake oilfield to its mouth on Mud Lake, just west of Taylor Lake Village on the eastern edge of the Lyndon B. Johnson Space Center (at 29°34' N, 95°04' W). The creek flows through urban Pasadena into a flat grassy prairie surfaced by clay and sandy loams that support wild hickory, holly, oak, elm, and ash. The area was the site of an early Cajun settlement. The 1,600-acre Armand Bayou nature preserve surrounding the bayou protects the interlocking ecologies of prairie, marsh, and forest, the indigenous habitat of the area, and was one of the state's first urban wilderness preserves. The preserve was established after a 1970 campaign to rename the bayou for Armand Yramatagui, a leader of the 1960s environmental crusade who was murdered in January 1970, and is operated by the Committee to Preserve Armand Bayou, a nonprofit corporation formed in 1974. The reserve remains outside the state park system.
