Course
From the confluence, the Buffalo trends basically northwest for several miles, crossing into Lewis County, where it is crossed by the Natchez Trace Parkway. The confluence with the Little Buffalo River is in Lewis County as well, along with that of several other more minor tributaries. The stream is paralleled for a distance and then crossed by State Route 99 while flowing through the broad Texas Bottoms. In Lewis County, although meandering, the course of the stream is basically westward. Entering into northern Wayne County, the stream receives several more tributaries, most notably the Green River.
A few miles below the mouth of the Green River near the community of Flatwoods, the Buffalo is bridged by State Route 13 and then turns to run a northerly course for the balance of its flow. It also crosses into Perry County near here. For most of its flow through Perry County, the Buffalo is roughly paralleled by State Route 13. Shortly after crossing into Humphreys County, it is bridged by Interstate 40. A few miles north of this is its confluence with the Duck.
