The Sabine-Neches Navigation District operates saltwater barriers

Saltwater Barriers

The saltwater barriers at SNND’s Taylor Bayou facility control saltwater intrusion in the Taylor and Hildebrandt Bayous of southeast Texas.

These barriers maintain the proper mix of saltwater and freshwater for the bayous, benefitting local rice fields and agriculture crops.

Flood Control

In cooperation with Drainage District #6, SNND also uses these barriers as flood control gates for Jefferson County.
Almost 90 percent of the water that falls in Jefferson County passes through the navigation district’s Taylor Bayou facility.
SNND’s new floodgates will provide a higher flow capacity, allowing SNND to let water into the bayou storm and prevent storm surges from flooding the area.

Navigational Locks

The facility includes a 15-foot-deep lock, which services traffic passing between the Intracoastal Waterway and Taylor Bayou.

The Sabine-Neches Navigation District, a political subdivision of Texas, works to responsibly manage, advocate for and improve the ship channel and navigable waters of Jefferson County to enhance the economy, environment and quality of life in Southeast Texas.


The lifeline that drives the economies of Southeast Texas

The Sabine-Neches Waterway, or the ship channel, is a “highway” through which more than 125 million tons of cargo is transported each year to energy, petrochemical and military users.
