VINCE'S BAYOU. Vince's Bayou rises near the Geneo Airport in southeast Harris County (at 29°40' N, 95°12' W) and runs northwest, through Pasadena, for nine miles to its mouth on Buffalo Bayou (at 29°43' N, 95°13' W). The stream flows through soil composed of calcareous clays with some shallow to deep sandy loams. Development along its course has been extensive, but in undeveloped areas the terrain varies from flat to rolling prairie with local dissections. Native vegetation consists primarily of mesquite, grasses, and cacti.
