Henri Castro, who colonized this area in the 1840s, envisioned irrigated farms along the Medina River. The project was delayed, however, until after the turn of the century, when Dr. Fred Stark Pearson, an internationally known engineer, persuaded British investors to finance construction of a dam at this site. Completed in 1912, Medina Dam was hailed as the largest in Texas and the fourth largest in the United States. Limestone boulders from a nearby quarry added bulk to the massive concrete structure. Four miles downstream, a small diversion dam conducted water into a system of irrigation canals. Gravitational force delivered the water to fields. The outbreak of World War I (1914) disrupted ties with British investors. Seeking new capital, Dr. Pearson and his wife left for England in 1915 on the "Lusitania" and were killed when a German submarine torpedoed the ship. The irrigation network created by Medina Dam brought new prosperity to this region. Vegetables raised in irrigated fields became a valuable crop. Water and electricity were made available to rural residents. In 1925 voters established the Bexar-Medine-Atascosa Counties Water Improvement District No. 1 to manage the project.

Texas random facts
Medina County, Texas, located in the southern part of the state, has a rich history that dates back thousands of years. The area was originally inhabited by various Native American tribes, including the Coahuiltecan and Lipan Apache, who lived off the land and traded with neighboring tribes.

In the 17th century, Spanish explorers arrived in the region, claiming the land for Spain. The Spanish established missions in the area to convert the Native Americans to Christianity and to further their control over the territory. One of the most notable missions was Mission San Francisco de la Espada, which still stands today and is a popular tourist attraction.

During the 19th century, the area that is now Medina County became a part of the Republic of Texas after it gained independence from Mexico. As more settlers moved into the area, the town of Castroville was founded in 1844 by colonists led by Henri Castro. The town became a major hub for German immigrants, and their influence can still be seen today in the town's architecture and cultural heritage.

Over the years, Medina County has experienced significant economic growth and development. The discovery of oil in the early 20th century led to an oil boom in the area, and agriculture has also played a significant role in the county's economy, with cattle ranching and crop farming being major industries.

Today, Medina County is a thriving community that celebrates its rich history and diverse cultural heritage. Visitors can explore the area's historical sites, such as the missions and historic downtown areas, while also enjoying the natural beauty of the surrounding countryside.
