(From Blue Legacy's Expedition: Blue Planet)

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 in Canada. (The sedimentation in the river led to its nickname, "Chocolate River" due to the brown tint.) 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. Victory was realized 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.

In July 2010, Alexandra Cousteau and her international Expedition Blue Planet team departed on a 14,500-mile journey across North America to investigate global water issues "in the backyard" of one of the world’s leading economies. Living, working and exploring water stories together, Alexandra and her team will use everything from the underwater gear invented by her grandfather to the latest in satellite technology and live social media to bring the thrill of adventure and the wonders of nature to audiences across the globe.
