The second in the TRCA's Lake Ontario Evenings series included a discussion on invasive species, and the MNR speaker touched briefly on this system, which allows endangered American eels to migrate from the Sargasso Sea into the upper St. Lawrence River and Lake Ontario. The passageway, including this shallow metal trough, facilitates the eels' passage over structures such as power dams.
