Figure 7-2: Long-term average salinity values for selected stations in the Nueces River and Rincon Bayou before 

 (a) and after (b) implementation of the demonstration project. Station numbers coincide with those in Figure 7-1 . 

 Salinity values for the upper-most reach of Rincon Bayou (near Station 67) during the before-project period (a) were 

 unavailable but were estimated by extrapolation to be approximately 45 ppt. RR indicates the point at which each channel 

 is crossed by a railroad.
