DOI Talk: Requiem for the Santa Cruz

Requiem for the Santa Cruz: An Environmental History of an Arizona River was just presented in the Rachel Carson Room of the Main Interior Building, 1849 C St., NW, Washington, DC.
Many lessons for the San Pedro River….

Excerpt from the talk on the Tucson and San Xavier reaches of the Santa Cruz River in the Tucson Basin:

THIS IS THE SAME PLACE IN JULY OF 1890. FOUR MAJOR FLOODS 10 DAYS APART. IT TOOK SAM HUGHES’ DITCH AND TURNED IT INTO THIS… HEAD CUT MIGRATING THROUGH THE VALLEY RAPIDLY. THIS IS NOT HAPPENING IN DAYS. THIS IS HAPPENING IN HOURS.

THE HEAD CUT ITSELF FROM SAM HUGHES’ DITCH… THERE WAS A GUY THAT REFERRED TO IT TAKING A WALK TO SILVERLAKE BECAUSE THAT IS WHAT IS HAPPENING. THIS MONSTROUS HEAD CUT IS ERODING AND FORKS WHERE YOU SEE THE ISLAND. THAT ISLAND IS GONE IN A MATTER OF DAYS. IN A FEW HOURS, IT HAS ALREADY ALMOST REACHED SILVERLAKE. THE NEWSPAPERS ARE REPORTING ON THIS. THIS IS AN ENVIRONMENTAL DISASTER. IMAGINE YOUR AGRICULTURAL LAND AND YOU NOW HAVE THIS CHANNEL MOVING UP THE VALLEY. YOU HAVE NO WAY OF PREDICTING WHAT IT IS GOING TO DO. IT MOVES REALLY FAST. I THINK IT WAS THREE KILOMETERS UPSTREAM WITHIN 72 HOURS.
