A submersible canal bypass is used to successively bypass the flow around distinct sections of an earthen canal for lining. The canal bypass is placed within the canal and uses a plurality of pipelines and a plurality of bulkheads assembled from portable modular sections. The headgates on the portable modular sections are so arranged along the bulkhead to divert the flow of water through bypass pipelines so as to isolate a section of the canal during lining activities and return the flow of water to the lined canal after lining.
