The San Antonio River is a major waterway that originates in central Texas in a cluster of springs in midtown San Antonio, about 4 miles north of downtown, and follows a roughly southeastern path through the state.[3] It eventually feeds into the Guadalupe River about 10 miles from San Antonio Bay on the Gulf of Mexico. The river is 240 miles long and crosses five counties: Bexar, Goliad, Karnes, Refugio, and Wilson.
