Sowell Mill Pk Boat Ramp (also known as Leftwich Bridge) is a gravel access area on the Duck River in Maury County offering access from both sides of the river.

The ramp is suitable for canoes and kayaks but difficult for launching powerboats due to gravel, mud, and a drop-off to the water, with limited parking available.

This location serves as a midpoint access for paddling trips through the scenic Yanahli Wildlife Management Area.
