Williamsburg Road crosses a tributary of the South River about 150 yards south of the Route 116 intersection, and a smaller one another 200 feet further south.
Williamsburg Road tributaries
This smaller tributary is about 200 feet south of the first, along Williamsburg Road. It drains mostly forested land, with some farmland just upstream of this location.
Notice the meander patterns and small floodplain created by the stream. Even streams this small (probably a first order stream) can exhibit these classic fluvial land forms.
