HATCH—After 13 years, Texas and New Mexico have finally reached a settlement in a Supreme Court case over Rio Grande water management. The settlement requires New Mexico to reduce the amount of water drawn from wells that deplete the flow of Rio Grande water to Texas. Norm Gaume, a former New Mexico Interstate Stream Commission director who now leads the nonprofit New Mexico Water Advocates, compared the Rio Grande to a company in bankruptcy. The settlement “is going to change the way we view water and use water in the Lower Rio Grande in New Mexico,” he said. Snowmelt runoff, the primary water source for the Rio Grande basin in New Mexico, has decreased 17 percent since 2000.
