The American Rio Grande Land and Irrigation System

Mercedes, Hidalgo County, Texas

Marker Inscription

Land developer B. F. Yoakum saw agricultural potential along the Rio Grande and found investors in 1905 for an irrigation project. They purchased 250,000 acres and the townsite of Mercedes for business headquarters. The pump station began operating in 1908. The system had grown by 1920 to three large canals, miles of branches, and five pumping plants. In 1930 the Hidalgo and Cameron County Water Control and Improvement District took over the system which continues to serve the farming area of the Lower Rio Grande Valley. (1979)

The Story

In 1905, at the dawn of the Lower Rio Grande Valley's transformation into an agricultural powerhouse, developer B. F. Yoakum gathered investors to turn arid brushland into irrigated farmland. Their company bought a quarter-million acres and built the townsite of Mercedes as its headquarters, and by 1908 pumps were lifting river water into a growing web of canals. Within a dozen years the system had swelled to three main canals and five pumping plants, and it passed to public water districts in 1930 that still serve Valley farmers today.

Why it matters

Large-scale irrigation companies like this one turned the semi-arid Rio Grande borderland into one of America's most productive farming regions, a defining chapter in the settlement and commercial development of South Texas.

Don Florencio Saenz Homestead

Progreso Lakes, TX

On land his family held by Spanish grant, Don Florencio Saenz built his homestead in 1902 as the headquarters of the sprawling Toluca Ranch, which once reached seventeen miles north from the Rio Grande. From here he ran a mercantile store and championed cattle ranching and irrigated river farming as the future of the lower Valley. In 1915, amid the cross-border turmoil of the Mexican Revolution era, raiders tried to burn the house and were driven off by U.S. soldiers in a fight that cost a private his life.

Rancho de Santa Maria

Santa Maria, TX

This ground was part of Spain's 1777 La Feria Grant, partitioned in 1843, and by the 1850s hosted a sub-post serving Forts Brown and Ringgold on the Rio Grande frontier. In 1870 L. J. Hynes built the compound that still stands, with buildings for a dairy, kitchen, and ammunition; as first postmaster in 1876 he ran a stage depot, general store, telegraph office, and river wharf. Frank Rabb bought the ranch in 1892, and in 1916 the U.S. Army made it a headquarters amid the era's border troubles.

Run

Donna, TX

Once part of the Cavazos family's mid-1800s Asadores Ranch, this stretch of the Rio Grande Valley was transformed at the turn of the 20th century when East Texas rice farmers and other newcomers organized irrigation companies and coaxed the railroad into the area. The tiny community of Run took its name from postmaster Ed Ruthven, whose store, a school, and his brother's irrigation pumps briefly anchored local life. A devastating flood in 1909 sent many residents drifting toward nearby Donna, and Run faded soon after.

Santa Ana Land Grant

Alamo, TX

The 15-square-mile Santa Ana grant was awarded by Mexico to Benigno Leal in 1834, who set up his Rancho de Adentro headquarters and cemetery on this ground. Over the following century the land passed through the hands of canal and land companies that converted much of the surrounding country to irrigated farmland in the early 1900s. A stretch along the river kept its native forest and became the Santa Ana National Wildlife Refuge in 1943.
