Because of water use upstream little flow from the 1450-mile Colorado river 2330 kilometers has reached the sea in 50 years.
Zamora watched the high tides make the final link between river and sea last week via a pilot channel dug by the Sonoran Institute to increase freshwater flow into the Gulf of california.
Colorado river Connects With Sea The reunion is the end of a 53-day journey for the long-planned Colorado river pulse flow an artificial flood meant to restore the river's parched delta.
