Medina Dam

Duane's take

Here's how the official marker at Medina Dam tells it, and I'll do my best to do it justice. Now, some stories start with a dream and end with a dam. This one starts with a dream, ends with a dam, and somewhere in the middle takes a turn so dark you'd almost rather it stayed a dream.

Go back to the eighteen forties. A man named Henri Castro was colonizing this corner of Texas, and he looked at the Medina River and saw something most folks see in a river — water. But Castro saw irrigated farms.

Fields drinking deep, crops stretching to the horizon. It was a vision. It was also, for a good long while, nothing but a vision, because the project got delayed.

Decades rolled by. The century turned. Then along came Dr.

Fred Stark Pearson — internationally known engineer, the kind of man who could walk into a room full of British investors and walk back out with their money. Which is exactly what he did. He persuaded those investors to finance construction of a dam right here on the Medina River, and in nineteen twelve, Medina Dam was completed.

Completed and immediately hailed. Hailed as the largest dam in Texas. The fourth largest in the entire United States.

That's not a small thing to put your name on. Limestone boulders hauled from a nearby quarry added bulk to an already massive concrete structure. Four miles downstream, a small diversion dam sent water into a whole system of irrigation canals, and from there, gravitational force — just plain old gravity — carried that water out to the fields.

No pumps. No fuss. Just physics doing the heavy lifting.

Vegetables became a valuable crop. Water and electricity reached rural residents who'd done without. The dream Henri Castro had carried in the eighteen forties was, decades later, finally walking around in the world.

But then nineteen fourteen arrived, and with it, World War I. And the ties to those British investors? Disrupted.

The money side of things got complicated in a hurry. Dr. Pearson needed new capital, so in nineteen fifteen, he and his wife boarded a ship bound for England.

The ship was the Lusitania. You know where this is going, and it is every bit as grim as you think. A German submarine torpedoed the Lusitania, and Dr.

Fred Stark Pearson and his wife were killed. The man who built the fourth largest dam in the United States, who turned a colonizer's forty-year-old dream into working canals and irrigated fields — gone, just like that, in the middle of the Atlantic. The project survived him.

In nineteen twenty-five, voters established the Bexar-Medina-Atascosa Counties Water Improvement District Number One to manage things going forward. The irrigation network held. The prosperity it had brought to the region held too.

Henri Castro imagined it in the eighteen forties. Fred Stark Pearson built it in nineteen twelve. And the Medina River just kept on running, the way rivers do, indifferent to the ambitions and the losses of the people who tried to put it to work.

What the marker says

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-Medina-Atascosa Counties Water Improvement District No. 1 to manage the project. (1978)
