Water

Water is, and always has been, critical here in South Texas. If there isn't enough water in some seasons, it comes in great floods in others. San Antonio has a history of many floods which created wide spread damage. Pictured here is the flood control intake for a 24' tunnel which diverts water about three miles south of the city. This means that much of the water in the River Walk is not river water, but pumped up from the Edwards Aquifer and then pumped back up to the beginning of the River Walk. The flow of water along the River Walk is the result of continuous pumping so the water level remains constant come drought or deluge.
