It originates at the confluence of the East Sepulga and West Sepulga rivers and discharges into the Conecuh River near the northwestern border of Conecuh National Forest.

If Creek, it is possibly from asi meaning "yaupon" and algi meaning "grove".

If Choctaw in origin, the name is possibly derived from shoboli, which means "smoky".
