Salinity levels in Sabine tend to be lower, thus saltwater intrusion is less of an issue. Various factors contribute to lower salinity in Sabine:
1. More freshwater flow due to draining much larger watersheds. Also dammed reservoirs releasing fresh water for power generation during low rainfall periods.
2. Weaker coupling between Sabine Lake and the Gulf of Mexico. The southern end of Sabine lake is less connected to the ship channel.
In addition, the marsh between Sabine and West Cove may simply be less susceptible to saltwater intrusion. Possible explanations:
1. The soil is slightly higher in elevation. As much as 6" would make a big difference in saltwater intrusion.
2. The soil types on that part of Cameron may be less susceptible to saltwater intrusion.
