Invasive aquatics choke Rio Grande
aquatic weeds are creating an international incident, of sorts, along the
Mexican-U.S. border. Hydrilla and water hyacinth are clogging the Rio Grande to
the point where many Mexican communities that use the river have no water
whatsoever. Brownsville, Texas, which also utilizes the Rio Grande, has had no
supply interruptions due to pumping and reservoirs that are used to store water.
