Brazos Bend Volunteer Organization

Volunteers have been a vital part of Brazos Bend State Park since its opening in 1984. The volunteers organized in 1989 by electing officers and accepting by-laws. We operate as an independent, nonprofit 501(c)(3) organization. The Brazos Bend volunteers have been recognized for the highest number of volunteer hours, 15,821, for any park in Texas. The volunteers have demonstrated teamwork and quality in support of Brazos Bend State Park.

We are a diverse group of individuals with a common interest in nature and the environment.  Our purpose is to assist and educate the visitors of Brazos Bend State Park through information and interpretive programs and to assist in the care and conservation of this 5,000-acre park.
