Welcome to BMA

Conservation Projects

Medina Reservoir was constructed from 1911-1912 as an irrigation reservoir. An extensive canal system delivers water by gravity flow to 33,000 acres of irrigated farmland below the Balcones escarpment around Castroville, La Coste, Natalia, and Devine.

Water Issues

BMA is well aware of problems facing the Reservoir system and will be posting educational information on our website. Water quality is a very important issue as it relates to the state water impounded by the Medina/Diversion Reservoir system.

Our History

Deeply Rooted in the Golden Valley of Medina

BMA’s history is fascinating. From the Medina Dam project, to the countless miles of irrigation canals, our story is embedded into our surrounding communities.

What’s New!

B.M.A. will frequently update our site with news and information regarding operations, meetings and any policy changes. If you have a story you would like to submit along with photos, please contact us. We would love to share your story!
