Sabine is a bit different from Calcasieu. The ship channel is not as deep for the same distance N (Port Arthur is much further south than Lake Charles). Consequently, there are lower volumes of salt water influx. Furthermore, due to the smaller and shallower openings between the ship channel and the southern end of Sabine Lake, the ship channel actually delivers more salinity to the northern end of Sabine Lake (NW corner). Sabine Lake's more common salinity gradient is from more saline at the N to less saline at the S.

Toledo Bend dam also provides more regulation and tends to even out the fresh water input so that even in dry periods, releases from the dam keep the fresh water flowing in so that big, upward salinity swings are much less common. Consequently (as shown in attachment), the marsh losses E of Sabine tend to be smaller than the marsh losses W of Big Lake.
