The Rio Grande River's Controlling Infrastructure. This map illustrates the series of upstream dams, reservoirs, and channels deployed to manage the RioGrande River's water flow and represents astatic Mexico-United States border. The systemization of the Rio Grande River overburdens an already over-tapped water supply, whereas limited natural hydrological cycles endanger the resolution of the boundary. Parallel to the river path is a stagechart that indicates the river's surface level recorded at each dam. The data in this drawing was provided by the International Water and Boundary Commission Rio Grande Flow and Reservoir Conditions Chart, except for the Caballo Dam,which was provided by the Advanced Hydrological Prediction Serviceson the National Weather Service.
