Clayton, NY, Jun 29, 2009 — July will be a month of celebration and reflection as the St. Lawrence Seaway, and its locks, channels, and hydropower dam near Massena, turns 50. The waterway brought global trade to the St. Lawrence River, but also pollution, invasive species, and one catastrophic oil spill. More than 50 environmental groups across the region are releasing a seven-point agenda for a cleaner future for the Seaway. Jennifer Caddick directs one of those groups, Save the River, based in Clayton. She told David Sommerstein the 50th anniversary is bittersweet for residents of the Thousand Islands.
