For 14 consecutive years, Texas has claimed Site Selection magazine’s Governor’s Cup, a benchmark of investment and job creation, much of it underpinned by trade and investment with Mexico that flows through San Antonio from the border region. The streak helped define the “Texas Miracle,” where pro-growth policy, a strong workforce and steady expansion come together. But that success now faces a critical constraint: water.
Competition from other states is familiar. What is new, and more consequential, is the growing risk that Texas may not have enough water to sustain its trajectory. Across the state, from the Coastal Bend to the Hill Country, reservoirs are declining and communities are scrambling to secure supply. Nowhere is the challenge more acute than along the Texas-Mexico border.
The Rio Grande is not merely a line on a map. It is the lifeblood of the border region, sustaining millions of residents, irrigating farmland that feeds the country and anchoring cross-border commerce. Yet that lifeline is under unprecedented strain.
Decades of drought, population growth and aging infrastructure have pushed the river system to a breaking point. Less than one-fifth of historic flows now reach the Gulf of Mexico. The Rio Grande ranks among America’s most threatened rivers, but in South Texas this is the reality.
Counties across the Rio Grande Valley have declared repeated water emergencies. Farmers cannot be certain they will have enough water to plant or harvest. Cities such as McAllen and Brownsville, alongside Reynosa and Matamoros, face mounting pressure on municipal supplies, creating risks for households and industry alike. If South Texans are serious about their economic future, addressing water infrastructure along the Rio Grande must be central to its strategy.
Meeting this challenge will require more than incremental fixes. Water policy must match the scale of the problem at the local, state, federal and binational levels. The river ignores political borders, and solutions must transcend them.
For more than three decades, the North American Development Bank, based in San Antonio, has shown what cross-border cooperation can achieve. Created by the United States and Mexico, it finances environmental infrastructure that improves quality of life and strengthens economic resilience.
Its $400 million Water Resiliency Fund, launched last year, focuses on practical steps such as conservation, system modernization and supply diversification. In its first round in the Rio Grande Valley, irrigation districts submitted 21 proposals totaling roughly $225 million. These projects include lining canals, replacing open ditches with pipelines and upgrading delivery systems to reduce water loss.
The payoff could be substantial. Early estimates suggest these projects could save more than 55,000 acre-feet each year, about 49 million gallons a day, enough to serve roughly 600,000 residents. That is water that would otherwise be lost.
Texas has also responded. Voter approval of Proposition 4 and funding commitments from the Texas Water Development Board, including $100 million for Valley irrigation districts, reflect growing recognition that water security is economic policy. Combined with NADBank financing, these investments can move projects forward faster than either effort alone.
Still, infrastructure is only part of the story. Water underpins economic stability, agricultural productivity and community well-being. Without it, growth slows, investment hesitates and opportunity narrows.
The Texas Miracle was built on practical leadership and long-term thinking. Preserving it will require the same approach, now applied to water with urgency. If Texas intends to remain a magnet for growth, it must ensure that prosperity is not constrained by scarcity.
Along the border, the path forward is clear. Invest in conservation, modernize delivery systems and expand alternative supplies to reduce dependence on an overburdened river while strengthening collaboration across borders.
