The river was first discovered by Spanish explorers in the 1600s, and it was named after the La Vaca ("the cow") Indian tribe who lived in the area. The Lavaca River is fed by several tributaries, including the Navidad River, and it eventually empties into the Gulf of Mexico.

There are several reservoirs and dams along the Lavaca River, including the Lake Texana Dam and the Lake Sweetwater Dam. These dams provide water for irrigation and drinking purposes, as well as recreational activities such as fishing and boating. The Lavaca River also supports a variety of wildlife, including bass, catfish, and alligator gar. The river and its surrounding areas are used for agriculture, including cattle ranching and crop production. Overall, the Lavaca River is an important natural resource for the state of Texas.
