When I turned one year old, my parr marks began to disappear, alerting me to the fact that my first great journey would soon begin. I knew it was time to go to the ocean. Under natural conditions, it would be an arduous journey: over 450 miles of river fraught with predators, rapids, strong currents, and changing salinity that culminates in a rapid biological adaptation to the ocean. Unfortunately, man-made obstacles such as agricultural runoff, heat pollution, stagnant water and dams further complicated my voyage.
