The local persistent current in two-dimensional strongly interacting systems is investigated. As the interaction strength is enhanced, the current in the sample undergoes a transition from diffusive to ordered flow. The strong interacting flow has the characteristics of a plastic flow through dislocations in the pinned charge density wave that develops in the system at low densities.
