Historically the estuary was a huge area. It was a vast plain of tidal influence and
freshwater floods that changed every year. Recreating an estuary, even a small estuary,
at the mouth of the river would bring back birds, would bring back marine life. It would bring back fish. And, it would help the people. The flow to the ocean has been disrupted ever since the dams were constructed on the river. This place at the estuary is critical to maintaining
millions of birds passing through from South America to Alaska every year—and back. It is a world-class treasure, and the cost
of restoring it is small compared to its value. What you can learn here in trying to engineer
an estuary at the mouth of the river can be used in other parts of the world.
