The river begins near the town of Poteet in Atascosa County and flows southeast into the Gulf of Mexico. Historically, the Atascosa River was a crucial water source for early Spanish explorers, and later for ranchers and farmers in the region. Today, it supports a variety of agricultural activities, including cattle ranching and irrigated farming. The river also has several reservoirs, including the Choke Canyon Reservoir and the Calaveras Lake, which provide drinking water and recreational opportunities for nearby communities. Despite ongoing conservation efforts, the Atascosa River faces challenges including pollution, overuse, and habitat loss.
