Probably the least-known tributary of the Alapaha River, the Little Alapaha River is so shy it disappears underground between Jennings and Jasper, Florida.
The Little Alapaha River arises in Echols County, Georgia, just before it flows into Hamilton County, Florida, where it falls into a sinkhole west of Jasper, briefly reappearing before vanishing again. Theoretically it is a tributary of the Alapaha River, but it is not clear the waters of the Little Alapaha River ever reach the Alapaha River aboveground. Like the Alapaha River, the Little Alapaha’s sinkhole disappearance happens at the Cody Scarp.

WWALS will mention it as a tributary in the Alapaha River Water Trail, but is not clear there are any boating opportunities on the Little Alapaha River.
