Tinker Creek begins in an unnamed lake near Lackawanna Mountain in Clifford Township. It flows south-southwest for a few tenths of a mile before turning west and entering a wetland. Here, the creek turns north for several tenths of a mile before receiving an unnamed tributary from the right and turning west-northwest. After a few tenths of a mile, it receives an unnamed tributary from the left and turns north-northwest for several tenths of a mile before heading in a westerly direction for more than a mile. The creek then turns northwest, and after a short distance, reaches its confluence with East Branch Tunkhannock Creek.
