description Lavaca River Delta Overview
The Lavaca River Delta is the low-lying river-mouth area where the Lavaca River enters Lavaca Bay on the Texas Gulf Coast. It is an estuarine landscape shaped by the interaction of river water, tides, and shallow coastal wetlands, including marsh habitat. These waters and wetlands provide habitat for estuarine wildlife, including shrimp and oysters that are important to regional commercial fisheries. The delta is part of the wider Lavaca Bay coastal system.
