DRAFT Figure 3-16 illustrates salinity in the river with no flow at the dam and average flow from Sulphur Springs uncorrected for withdrawals (31 cfs). Salinity near Rowlett Park Bridge (km 16) is between 6 and 7 ppt, which is similar to the long-term median value for that site in the EPCHC data set (Figure 3-14). This figure also shows a shallow lens of low salinity water at the surface near Sulphur Springs. Similar to the empirical box and whisker plot (Figure 3-13), modeled surface salinity values there (4-5 ppt) are lower than at Rowlett Park. The river near Sulphur Springs is highly stratified, as bottom salinity values at 10 to 11 ppt. The reverse salinity gradient in surface waters and pronounced salinity stratification in the vicinity of Sulphur Springs is a distinct characteristic of the river during no-flow conditions. The next three figures show the effects of different flows of fresh water from the reservoir spillway on salinity in the river. A flow of 10 cfs of river water creates a zone of water less than 1 ppt and pushes the 7 ppt isohaline (line of equal salinity) on the river bottom to kilometer 13.4 near the dam (Figure 3-17). A flow of 60 cfs creates a freshwater zone of
