1. Nueva Street Dam and Marina Marker

Inscription.
The river in the downtown area is kept at a constant level by floodgates located just below the Nueva Street Bridge. The gates open during heavy rains, allowing water to pass safely from the upper to the lower channel. When this occurs, other gates at both ends of the heavily developed river loop are operated to maintain a constant water level in that area. River barges are serviced and stored at a marina underneath Nueva Street. During floods, an inflatable dam protects the marina, providing a safe harbor for the barges. Floodgates that are located approximately one mile downstream from here maintain the constant water level between Nueva and South Alamo Streets.
