In "Urban Watersheds: Runoff to Renewal" Alexandra Cousteau's Expedition Blue Planet explores the hidden world of water under Toronto, Canada's largest city. In this short film, Alexandra Cousteau examines the role of rivers in our urban ecosystems and interviews Lake Ontario Waterkeeper Mark Mattson and Lost Rivers Founder Helen Mills - among others - to learn of their vision of a healthy urban hydrosphere.

This short film tells the story of the Petitcodiac River which was almost dead, strangled by a causeway built across its width in 1968 on the outskirts of Moncton, New Brunswick. The causeway practically dammed the river, and as a result fish numbers in the river plummeted. Thus began a protracted battle to restore the river to its former glory, which saw victory this April when, for the first time in 42 years, the gates on the causeway were opened for good restoring free flow between this unique tidal river and the sea.                  Alexandra Cousteau
